GA Review

Article (edit | visual edit | history) · Article talk (edit | history) · Watch
Hi, I'll be reviewing this article. The rules for GA reviews are stated at Good Article criteria. I usually do reviews in the order: coverage; structure; detailed walk-through of sections (refs, prose, other details); images (after the text content is stable); lead (ditto). Feel free to respond to my comments under each one, and please sign each response, so that it's clear who said what.

When an issue is resolved, I'll mark it with Done. If I think an issue remains unresolved after responses / changes by the editor(s), I'll mark it Not done. Occasionally I decide one of my comments is off-target, and ~~strike it out~~ --

BTW I've occasionally had edit conflicts in review pages, and to reduce this risk I'd be grateful if you'd let me know when you're most active, so I can avoid these times. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

Coverage

YHas all the usual sections for a bird article. I may have comments within sections. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]
Done Nothing about cultural representations? --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

None I can find - an Arctic breeding wetland bird isn't a prime candidate, and the connection with the Tudor collar is a reverse link jimfbleak (talk) 08:20, 10 June 2009 (UTC)[reply]

Fair enough. --Philcha (talk) 08:48, 10 June 2009 (UTC)[reply]

Structure

Y Fine at the top level. I may have comments within sections. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

Referencing of books

Y I'll have to AGF w the books, except where online editions are available. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]
Y I see you've centralised the biblio details for frequently-cited books, which is fine. But it's more helpful if the individual cites link to the biblio details of the book. Wikipedia:Citing_sources/Further_considerations#Wikilinks_to_full_references shows a method that works, but has limitations: assumes lastname+date is good enough info for the user and a unique identifier for the work; assumes hardback and paperback editions have the same pagination; doesn't allow for electronic editions. In my wanderings I've found a method that is more flexible, see for example refs to the game manual at Master of Orion II: Battle at Antares. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

That looks like a good method, which I'll bear in mind, but I'll leave refs as they are if there is no MoS issue

Taxonomy and nomenclature

Done I don't see how A supertree approach to shorebird phylogeny supports any of "The Ruff is a wader in the large family Scolopacidae, ... Sharp-tailed Sandpiper Calidris acuminata." --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

Figure 7, which is for the family Scolopacidae, shows the three species grouped together

Thanks. Not being an ornithologist the scientific names meant nothing to me. I've assed "Especially fig. 7" to the ref. --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

~~Genetic polymorphism for alternative mating behaviour ... and The resident's dilemma describe the Ruff as a species of sandpiper; this would be helpful. --Philcha~~ (talk) 14:17, 9 June 2009 (UTC)[reply]

added sandpiper link, although not as helpful as it seems since it's a redirect to Scolopacidae jimfbleak (talk) 11:23, 10 June 2009 (UTC)[reply]

I don't see where you linked (reviewer's blindness?), but I take your point. --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

Done Can you please translate the relevant passage from Linnaeus re Tringa. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

My Latin is too rusty to do a full translation, removed quote jimfbleak (talk) 08:45, 10 June 2009 (UTC)[reply]

The better part ... :-) --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

~~Can you please translate the relevant passage from Merrem re transfer to Philomachus.~~

I don't think I've quoted a passage jimfbleak (talk) 08:45, 10 June 2009 (UTC)[reply]

--Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

In the light of what we agreed about Linnaeus, .... --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

Done Please explain "leks", as this section precedes "Mating". If I were writing this (silence in the cheap seats!), I'd fancy a colloquial explanation like "mating fairs". Whatever the explanation is, a ref would be needed, possibly to an online dictionary. --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

Lek was linked in lead, but I like the change of phrase, fixed as "mating arena" jimfbleak (talk) 08:45, 10 June 2009 (UTC)[reply]

Apt. --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

Done Re "a later name reeve, which is still used for the female, is of unknown origin, but it may be derived from the shire-reeve, a feudal officer, likening the male's flamboyant plumage to the official's robes":
- Done Does Coker support that as well as the modern "ruff"? --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

Yes jimfbleak (talk) 08:45, 10 June 2009 (UTC)[reply]

- Y Seems odd that the female should retain a name that designates a male human. Any explanation? --Philcha (talk) 08:07, 9 June 2009 (UTC)[reply]

Ree or reeve was the original name for both sexes. When the male was likened to the collar, this would hardly apply to the female, which retained the old name. Although that too referred to the male's flamboyant plumage, I imagine the connection was long forgotten jimfbleak (talk) 08:45, 10 June 2009 (UTC)[reply]

Description

Done Should w-link gravy boat - some English-reading users may be non-European. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

Done jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done Does "deeper, slower wing action" mean "longer, slower stroke"? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

deeper, slower wing stroke now, kept deeper because longer could have a temporal meaning jimfbleak (talk)

Fair point. --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

Done Does "on the tail sides" mean "on the sides of the tail"? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

fixed jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Y "the male is much larger than the female and has a distinctive set of breeding plumages" appears to be contradicted by the "Mating" sections description of male forms:

This species shows sexual dimorphism; although a small percentage of males resemble females, the typical male... and has a elaborate breeding plumage. I think this rejig addresses the points below too jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Nearly, but omits the satellite stealth shaggers. How about e.g. "although there are three male forms, by far the commonest ..."? I think that would give readers enough warning without duplicating the "Mating" section. --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

The description of typical males includes the satellite shaggers. They are essentially the same as the territorial males in appearance except for the white ruff (included as one of the colour options they may be black, chestnut or white) The main differences between the territorial and satellite males, other than the ruff colour, are behavioural, not appearance. jimfbleak (talk) 14:47, 11 June 2009 (UTC)[reply]

OK, as the revised "Mating" section now handles it up-front. --Philcha (talk) 16:28, 11 June 2009 (UTC)[reply]

- Y(see above) In fact it appears to contradict the para's final sentence, " The extreme variability of the breeding plumage ..." --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]
- How about e.g. "Three adult male forms are known, but most are much larger ..."? With refs, of course.
- Then the following sentences should make it clear that they describe the largest and commonest male form. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]
- You might need to restructure to present features common to all male forms first - if any, as this may not apply if the female impersonator is indistinguishable from females at binocular range. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]
Done Img caption "Male in breeding plumage" needs to be changed accordingly. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

done

Done Please check whether para "Outside the breeding season, the male's head and neck decorations ..." needs to be changed a result of the multiple male forms. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

added normal male jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done "female weighs about110 g (3.9 oz)"? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

done

Y "In winter, her plumage is similar to that of the male" - presumably similar to that of the commonest male form? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

normal male, impersonator and female all have similar appearance in winter, so OK as is jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done I think "The juvenile Ruff resembles the non-breeding adult, but has neat, scaly upperparts with dark feather centres, and a strong buff tinge to the underparts" has a few problems:
- Y "resembles the non-breeding adult" - male or female? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

As above, they are similarly plumaged in winter

- Done"neat, scaly upperparts with dark feather centres" - OK, I think I can decipher this, but "neat, scaly upperparts" makes it sound like a lizard. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

The plumage of the juvenile Ruff resembles the non-breeding adult, but has neat, scaly-looking upperparts with dark feather centres, and a strong buff tinge to the underparts. jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

I've just realised there are earlier occurrences of "scaly" - my fault, I'm sorry. I suggest changing the first instance to "with a scale-like pattern" and the rest to "scale-like". --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

I don't like scale-like, it suggests texture rather than appearance. All occurrences now scle-like pattern or similar, or removed jimfbleak (talk) 14:53, 11 June 2009 (UTC)[reply]

That's really nice, thanks! --Philcha (talk) 16:19, 11 June 2009 (UTC)[reply]

Y The description of appearance is getting more complicated by the sentence - it's a chicken and egg problem, as you don't want to incorporate too much of "Mating" into "Description". I think the description needs a restructure, but I can't make concrete suggestions as I know very little of the facts (only what the article's told me so far). I think it's best to point out up-front that appearance varies in several ways: "normal" vs mating; 3 moults, incl intermediate stage; 3 male forms plus female form;. In a situation like this I'd probably create a sandbox page to try things out - my own sandox is more like a quarry! --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

(no longer needed, resolved by other means --Philcha (talk) 16:19, 11 June 2009 (UTC))[reply]

Y "The juvenile Sharp-tailed Sandpiper ... has a similar rich orange-buff breast" - article doesn't mention that feature of the female Ruff. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

the comparison is with the juvenile Ruff, which is described as such - female is only relevant because it is a similar size, juvenile male Ruff is much bigger than Sharp-tailed jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done I suggest the comparisons w Sandpipers should be at the end of the section, after the complexities of forms and moults have been (?)clarified. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

Done jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done "The Buff-breasted Sandpiper also resembles a small juvenile Ruff, but even the female Ruff is noticeably larger than the sandpiper, with a longer bill, more rotund body and scaly upperparts" - leapin' lizards, Batman! I think you have to explain what "scaly" means in this context. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

scaly-looking jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Y "Second-year birds" - "two year olds"? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

description by year is more normal for birds (except raptors) because it often links with plumage stages rather than exact calendar ages jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done Re "since they have a lower body mass and a slower weight increase than adults, it may be that energy constraints during migration are the main reason of the delayed moult":
- Y Need to explain "slower weight increase than adults" as non-ornithologists, incl me, generally think birds grow like cray in first year then slow down. --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

Juveniles certainly grow very fast, but second year birds are near adult. I'm just stating a fact here, I can't explain why they are less bulky jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

- Done"energy constraints during migration" needs explanation. E.g. "because they need to rebuild mass / energy reserves after migration"? Or "migration has reduced their mass and energy resevers, and their main need is still to grow to adult size"? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

and it may be that the demands made on their energy reserves during the migration flight are the main reason of the delayed moult. jimfbleak (talk) 09:36, 10 June 2009 (UTC)[reply]

Done Re "Juveniles moulted into their first winter body plumage during late September to November," the timespan looks earlier than for adults. Does that mean it's their first moult out of chick plumage? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

The juvenile plumage is the first stage after the downy non-flying chick plumage jimfbleak (talk) 10:01, 10 June 2009 (UTC)[reply]

Why not say so? E.g. " ... from their chick plumage to their first winter body plumage ..."? Some readers will know even less ornithology than I do. --Philcha (talk) 08:42, 11 June 2009 (UTC)[reply]

Juveniles moulted from their first summer body plumage into their first winter plumage... (not chick plumage, they have to lose that before they can fly jimfbleak (talk) 15:46, 11 June 2009 (UTC)[reply]

Thanks, much clearer. --Philcha (talk) 16:19, 11 June 2009 (UTC)[reply]

Y I did a little copyedit, is that OK? --Philcha (talk) 10:00, 9 June 2009 (UTC)[reply]

Thanks jimfbleak (talk) 10:01, 10 June 2009 (UTC)[reply]

Distribution and habitat

Done I think this section should explain up-front that most populations are migratory, and distinguish between breeding, non-breeding and permanent sites. How you structure it after that involves deciding whether to group by population (pop A winters at X, breeds at Y and migrates via Z) or to describe each type of site then the migrations. Again, you know the material so it's your call. --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

I'm not happy about about splitting migration around habitat. I've added In Great Britain and parts of coastal western Europe, birds may be present all year. "Permanent" may not be accurate - the winter and summer birds might not be the same (Black-tailed Godwit is present all year in the UK, but the breeding birds depart in autumn to be replaced by winterers from Iceland, which can be distinguished on size and plumage, unlike ruff)

I take your point about "permanent". However I'm less happy with the structure than first time round, possibly because I was focussing on phrasing and refs the first time. My inclination would be to take a top-down approach, e.g.: it's migratory, with winter quarters in warm regions and summer breeding grounds in sub-Arctic regions, and less-defined areas in W Europe; in both "seasons" it inhabits wetlands (describe); identify breeding grounds; identify winter quarters; describe migrations an dmention that non-breeders stay in winter quarters; fit gregariousness in where appropriate. --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

The Ruff is a migratory species, breeding in wetlands in colder regions of northern Eurasia, and wintering in the tropics, mainly in Africa. There is a limited overlap of the summer and winter ranges in western Europe. intro sentence - is this enough?

Oh, yes (waggling jowls) --Philcha (talk) 16:44, 11 June 2009 (UTC)[reply]

Done Pl explain / w-link leks, sedge, scrubland, wetland, irrigation, subsidence - we're not all naturalists. --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

done except lek, already linked twice jimfbleak (talk) 10:01, 10 June 2009 (UTC)[reply]

Are we still arguing about Ctenophore? :-) --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

Done "with shallow water margins" - "beside shallow water"? --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

removed margins jimfbleak (talk) 10:01, 10 June 2009 (UTC)[reply]

Y Is there any upper limit on cows per hectare? Is breeding of farmland wading birds depressed by a combination of predator abundance and grazing? suggests there is.--Philcha (talk) 16:53, 9 June 2009 (UTC)[reply]

Presumable there is an optimum, and overgrazing is mentioned later, but no specific figures - "moderately" is probably the key word jimfbleak (talk) 10:19, 10 June 2009 (UTC)[reply]

Y Would the distribution map (currently in info box), not be more useful here? BTW the permanent sites (coded green) are pretty near invisible at the any reasonable img size, how about making them red? Or even a darker green? --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

These are standard colours and placement for bird maps. The areas in which they are year round are tiny, but readily visible when the thumb is clicked - which is the point of thumbs jimfbleak (talk) 10:01, 10 June 2009 (UTC)[reply]

I'm not thrilled about the poor visibility, but take your point about standard colours.

What about placement?? -Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

Almost in the taxobox, unless there are multiple maps (I only know of one article with that) jimfbleak (talk) 15:29, 11 June 2009 (UTC)[reply]

Not sure what you meant by that, but I'll let FAC worry about it. --Philcha (talk) 16:44, 11 June 2009 (UTC)[reply]

Done "When not breeding, a wider range of shallow wetlands is used, ..." - "When not breeding, the birds use a wider range of shallow wetlands, ..."? --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

the birds use a wider range of shallow wetlands, such as irrigated fields, lake margins, and mining subsidence and other floodlands jimfbleak (talk) 10:19, 10 June 2009 (UTC)[reply]

Y "mining subsidence" is not a type of habitat, it's the cause of a type of habitat.

Done Re "increases the chances of a successful early return to its breeding area by the male":
- Done Does "successful early return" mean getting a territory, or some other reproductive advantage? The social implications of traditional use of lek sites in the ruff Philomachus pugnax (end of p 215) suggests the early bird gets his oats. --Philcha (talk) 14:17, 9 June 2009 (UTC)[reply]

I've added territorial to make it clearer that this is the main aim jimfbleak (talk) 10:19, 10 June 2009 (UTC)[reply]

Unless I've misread The social implications of traditional use of lek sites in the ruff Philomachus pugnax (end of p 215), getting there early correlates w reproductive success. I think e.g "and enables territorial males to reach the breeding grounds as early as possible, which appears to improve their chances of mating[ref]" would be clearer, and forges an implicit connection to the theory of evolution. --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

enables territorial males to reach the breeding grounds as early as possible, improving their chances of successful mating. jimfbleak (talk) 15:23, 11 June 2009 (UTC)[reply]

Thanks. --Philcha (talk) 16:44, 11 June 2009 (UTC)[reply]

- Done The current sentence structure looks bass ackwards to me, I'd prefer (subject to previous comment) "increases the male's chances of a successful early return to its breeding area." --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

and increases the territorial male's chances jimfbleak (talk) 11:23, 10 June 2009 (UTC)[reply]

Done "In the case of the Ruff, the larger size of the male may assist its wintering in colder regions than its mate" looks like academic-speak.

Y Re "The staging posts are closer together than the theoretical maximum travel distance calculated from the mean body mass" is there an article you can w-link to on the relevant theory? --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

Done "site-dependent refuelling strategy" - WTF does this mean? --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

at particular transit sites to feed, jimfbleak (talk) 12:57, 10 June 2009 (UTC)[reply]

"... intermediate sites ..." or "... stopover sites ..."? --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

changed to stopover -I knew there was a better word

I don't think referring to other species' "refuelling strategies" explains anything. After reading Stop-over strategy of Ruff Philomachus pugnax during the spring migration, as far as I can see: it says nothing about the Godwit or Redshank; the conclusions are hedged about with qualifications; the authors seem confident about optimal vs sub-optimal stopover sites (which might be the "site-dependent refuelling strategy" of the abstract; they tentatively conclude that flight stages are shorter than maxima predicted from body mass; but they note that the leanest birds found were leaner than theoretical minima, which suggest the theory is not robust; and there's no mention of "strategy" any where except the title. I'm not sure if any usable conclusions can be extracted, except perhaps the tentative but obvious one that the birds allow some safety margin between stopovers. My impression is that study of Ruff migration strategy is still at the early data-gathering stage, see e.g. Migrating Ruffs Philomachus pugnax through Europe, spring 1998, whihc cites Baccetti et al. --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

...calculated from the mean body mass, and provide evidence of a migration strategy using favoured intermediate sites. removed ref to other species, but I think it is clear that the birds are using "traditional" stopovers, not just landing at random within their safety margin, and i think that amounts to a strategy. It's common for several wader species to turn up at the same sites year after year on migration. jimfbleak (talk) 06:32, 12 June 2009 (UTC)[reply]

Thanks - "strategy" w/o explanation bugs me because the word is so vague - compare e.g. "foragig strategy" and "reproductive strategy". --Philcha (talk) 07:33, 12 June 2009 (UTC)[reply]

Doneish - I don't see how "Ruff store fat as a fuel for the long migration flights, but unlike mammals, they also use lipids as the main short-term energy supply for exercise and keeping warm" is supported by Energetics of a long-distance migrant shorebird (Philomachus pugnax) during cold exposure and running, which seems simply to say they ain't fussy eaters, especially before migrating. --Philcha (talk) 12:38, 9 June 2009 (UTC)[reply]

oops, wrong url, fixed now jimfbleak (talk) 12:57, 10 June 2009 (UTC)[reply]

Strictly speaking this is more about metabolic chemistry, and apparently shows a general contrast between birds and mammals - not surprising as their lineages diverged very early in amniote history, about 313 million years ago, (see cladogram at Evolutionary_history_of_life#Dinosaurs.2C_birds_and_mammals) and hence different routes to endothermy (see cladogram at Paleontology#Classifying_ancient_organisms). Leave it in for now, but ... --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

Done Energetics of a long-distance migrant shorebird (Philomachus pugnax) during cold exposure and running mentions 30,000km "air miles" (15,000 km each way?) during migrations. I think that's a goodie. --Philcha (talk) 10:43, 11 June 2009 (UTC)[reply]

Agreed, ...mainly in Africa, some Siberian breeders undertaking an annual round trip of up to 30,000 km (18,500 mi) to the West African wintering grounds. plus ref jimfbleak (talk) 06:13, 12 June 2009 (UTC)[reply]

Thanks, a bit of wow factor is nice for spicing up big articles. --Philcha (talk) 07:33, 12 June 2009 (UTC)[reply]

Behaviour

Y I'd have thought it was more logical to place "Feeding" and any other non-reproductive behaviour first, in case mating and nesting cause changes or in case "normal" feeding & territorial behaviour explains aspects of reproductive behaviour. --Philcha (talk) 11:37, 11 June 2009 (UTC)[reply]

this is the normal order, and I think it's swings and roundabout as to whether the alternative is better

Y Nothing about interactions w other birds or animals? --Philcha (talk) 12:50, 9 June 2009 (UTC)[reply]

and it is the only bird in which males have genetically determined differences in plumage and mating behaviour.[28] There are three male plumage types, one of which mimics the female. jimfbleak (talk) 12:57, 10 June 2009 (UTC)[reply]

Excellent. --Philcha (talk) 11:28, 11 June 2009 (UTC)[reply]

Done "The male-plumaged birds show two types of appearance and behaviour ..." is slightly misleading. I think it would be more accurate & informative to say, "Males show three types of appearance and behaviour ..." to include the female impersonators. --Philcha (talk) 14:17, 9 June 2009 (UTC)[reply]

see above jimfbleak (talk) 12:57, 10 June 2009 (UTC)[reply]

The way it's worded now has a really odd sentence structure - "There are three male plumage types, one of which mimics the female. The typical males show two types of appearance and behaviour; the territorial males have strongly coloured black or chestnut ruffs and stake out and occupy small mating territories in the lek. They actively court females ..." I think the problem is that the intro sentence is half-hearted - this seems to be a difference in style between you & me, I'm keener on signpost phrases and short passages. In this case we don't want the readers as confused as the birds, so I think good sign-posting is needed. How about e.g. "There are three male forms: the typical territorial males, satellite males and the very rare female impersonators. The ~~typical males show two types of appearance and behaviour; the~~ territorial males ..."? --Philcha (talk) 11:28, 11 June 2009 (UTC)[reply]

There are three male forms: the territorial males, satellite males which have a white neck ruff, and a very rare, recently discovered variant with female-like plumage. The territorial males... jimfbleak (talk) 15:18, 11 June 2009 (UTC)[reply]

Works a lot more smoothly, thanks.

I'm sorry, I missed something last time round - Genetic polymorphism ... gives approx breakdown 84% territorial, 16% satellite; and Permanent female mimics ... very strongly implies the % of female impersonators is minute. I think that's worth adding - it suggests territorials tolerate satellites because there are not enough satellites for it to be worthwhile for territorials to chase them away, see Genetic equilibrium. --Philcha (talk) 16:53, 11 June 2009 (UTC)[reply]

I'd already given the 16% satellite and 1% cross-dressers, now added the 84% for completeness. Total not 100 because of rounding and likelihood that 84/16 is for the obvious males. The reason the satellites are tolerated is in the text - females are attracted more to leks with both types jimfbleak (talk) 06:01, 12 June 2009 (UTC)[reply]

Thanks. --Philcha (talk) 07:37, 12 June 2009 (UTC)[reply]

I think it would be better to put the smallest group as "less than 1%" which fits in with the information in the references, and does not give an obvious 101% error. Snowman (talk) 08:29, 12 June 2009 (UTC)[reply]

Done "the resident or independent males" is not the term you use in the rest, and is rather nondescript. I prefer "territorial males", which is more descriptive and which you use lower down. --Philcha (talk) 14:17, 9 June 2009 (UTC)[reply]

done jimfbleak (talk) 12:57, 10 June 2009 (UTC)[reply]

Thanks, this is fairly complex for non-specialist readers, and I think consistency is important. --Philcha (talk) 11:28, 11 June 2009 (UTC)[reply]

Done At FAC you might get asked whether the satellite form is a recessive condition. The first source appears to say that's not known. But High frequency of polyandry in a lek mating system (begining of p 210) says territorials are "homozygous recessive" --Philcha (talk) 15:54, 9 June 2009 (UTC)[reply]

The gene for the territorial plumage and behaviour is recessive, and is only shown by males carrying two copies of the gene. jimfbleak (talk) 12:57, 10 June 2009 (UTC)[reply]

Done Why is a female impersonator known as "faeder"? Anything to do with Old English for "father"? (see "Fæder ūre" at Anglo-Saxon WP!) The source says it is. --Philcha (talk) 15:54, 9 June 2009 (UTC)[reply]

Added name origin jimfbleak (talk) 06:34, 11 June 2009 (UTC)[reply]

Thanks, I think that kind of lateral "hook" helps readers to remember. --Philcha (talk) 11:28, 11 June 2009 (UTC)[reply]

DoneGenetic basis of faeders not yet known. --Philcha (talk) 15:54, 9 June 2009 (UTC)[reply]

Found and added a ref to a dominant gene

Great find! However it's a preliminary result from on-going research, so I think it needs qualification. --Philcha (talk) 11:28, 11 June 2009 (UTC)[reply]

Nesting and survival

done jimfbleak (talk) 06:51, 11 June 2009 (UTC)[reply]

Done "The breeding density can reach 129 individuals per square kilometre" looks a bit of a stretch to me. The source up to 129/km² but nothing about breeding - although the density was measured in N. Russia, where they go in the breeding season. I'd strike "breeding" and put the sentence in "Habitat". --16:53, 9 June 2009 (UTC)

Thanks. --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

Done Please recheck the predators. The DEFRA paper says foxes only prey occasionally on waders, and http://www.abdn.ac.uk/staffpages/uploads/soi668/2008%20Van%20der%20Wal_Palmer%20Biol%20Lett.pdf Is breeding of farmland wading birds depressed by a combination of predator abundance and grazing? says feral cats and stoats are known in the area studied but their impact is not known. --Philcha (talk) 16:53, 9 June 2009 (UTC)[reply]

Predators of waders breeding in wet grasslands include birds. ..; foxes occasionally take waders, and the impact of feral cats and stoats is unknown. having said that, stoats are a nightmare for most breeding birds jimfbleak (talk) 06:51, 11 June 2009 (UTC)[reply]

Yeah, sources are like buses, ... --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

Done "ectoparasites" - "external parasites"? --Philcha (talk) 16:53, 9 June 2009 (UTC)[reply]

done jimfbleak (talk) 06:51, 11 June 2009 (UTC)[reply]

Done Ectoparasites from birds in Newfoundland says the Ruffs they saw looked free of ectoparasites, but said nothing about diseases. In fact Variation in the innate and acquired arms of the immune system among five shorebird species says ruffs are heavily affected by diseases in tropics. --Philcha (talk) 16:53, 9 June 2009 (UTC)[reply]

Adults seem to show little evidence of external parasites,[46] but may have significant disease levels in their tropical wintering grounds. Ruff occur in inland freshwater habitats where the likelihood of avian malaria infection is high,[47] and they might be expected to invest strongly in their immune systems;[48] however, an analysis showed that that this bird actually has surprisingly low levels of immune responses on at least one measure of resistance jimfbleak (talk)

"on at least one measure of resistance" is a nice finesse.

Unfortunately you seem to have messed up the refs for a couple of sentences. --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

Duh... I seem to have pasted back something i was copying to here - I think it's fixed jimfbleak (talk) 15:05, 11 June 2009 (UTC)[reply]

Done "Ruff occur in inland freshwater habitats where the likelihood of avian malaria infection is high,[46] and they might be expected to invest strongly in their immune systems;[47] however, an analysis showed that that this bird actually has surprisingly low levels of immune responses" is very dubious. Variation in the innate and acquired arms of the immune system among five shorebird species says, "It is perhaps surprising that ruffs exhibited low levels of immune response, as they occur in inland freshwater habitats where the likelihood of avian malaria infection is high (Mendes et al., 2005). This environment presumably would select ruffs to invest strongly in their immune systems (Piersma, 1997), but this hypothesis was not supported here. Note, however, that we did not measure cell-mediated immunity, a type of response known to be involved in the control of malaria parasites", i.e. it may heve better malaria resistance then the study's results suggested. --Philcha (talk) 16:53, 9 June 2009 (UTC)[reply]

With your little bow and arrow? --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

Y"On saline lakes in East Africa ... " appears to contradict other statements in the article and other sources that it's a freshwater bird. --Philcha (talk) 20:01, 9 June 2009 (UTC)[reply]

It breeds in freshwater habitat, but uses a wider range of wet areas for feeding. I think this is opportunist behaviour at a rich food resource. They don't probe in salt water in the way they do in marshes, but just pick the zillions of flies off the surface. It the same as gulls catching flying ants in the air when they swarm, or kestrels hunting insects on foot - it's not typical, but why pass up an easy feast jimfbleak (talk) 07:14, 11 June 2009 (UTC)[reply]

And we call them "bird brains"! --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

That's fine. --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

Done I don't see how the source supports "Fossils from the Pleistocene suggest that this species bred further south in Europe than it does now in the cool periods between glaciations." The most relevant pasaage I can see in the source is "Pleistocene find spots of particular species now living in northern Europe (Scandinavia) are situated to the south of the border line of the maximum transgression of the ice sheet in the Upper Pleniglacial of the last glaciation" (p 251) which is just a verbose way of saying "During the last Pleistocene glaciation they lived south of the ice sheets" (wow!) I'm also not sure what the value of this sentence is. --Philcha (talk) 22:28, 9 June 2009 (UTC)[reply]

Fossils from the Pleistocene suggest that this species bred further south in Europe in the cool periods between glaciations than it does now. does this order make more sense? The point of this, other than mentioning the fossil record, was to link to the following bit suggesting that it is an indicator of climate change, retreating north as global temperatures rise. In the cool of the Pleistocene, it could breed further south jimfbleak (talk) 07:30, 11 June 2009 (UTC)[reply]

This climate change business is complex, see Younger Dryas, Medieval Warm Period, Little Ice Age. IMO the cited source fails to consider this, but your "has led to suggestions" is an appropriate qualification. --Philcha (talk) 12:07, 11 June 2009 (UTC)[reply]

Relationship with humans

Y Harvesting status of migratory waterfowl in northern Iran: a case study from Gilan Province doesn't mention the Ruff - and you're not short of refs at this point. --Philcha (talk) 20:01, 9 June 2009 (UTC)[reply]
Y Nor does Sustainable harvest of waterbirds: a global review. --Philcha (talk) 20:01, 9 June 2009 (UTC)[reply]

I included these to demonstrate large scale hunting of waterbirds in the Ruff's wintering range. Waterbird hunting doesn't target particular species, just whatever is there, be it Ruff, godwits, Greenshanks or any other wader. I think there is a point to these refs, but I'll chop it if you think it is inappropriate or unnecessary jimfbleak (talk) 07:37, 11 June 2009 (UTC)[reply]

Links validity check

The link checker report shows:

Y A 301 redirect, but in this case it does go to the required content, not to a home or sales page. --Philcha (talk) 07:46, 12 June 2009 (UTC)[reply]
Several links w/o accessdate and other citation template params (incl author in Linnaeus work!). However Ruffs-Image documentation and later links are in "External links", and I think it's OK to leave those as-is. Please enter the missing citation params for those preceding it. --Philcha (talk) 07:46, 12 June 2009 (UTC)[reply]

I don't understand this - as far as I can see, all cite webs have an access date, and cite journal doesn't need them, since any link is to an on-line version of a "real document" and unlikely to change. Linnaeus is linked in the taxobox, the taxonomy section and in the cite book reference for Systema Naturae (in references). Surely that's enough? Could you give specific missed access dates/ author links?jimfbleak (talk) 12:32, 12 June 2009 (UTC)[reply]

Check for disambiguation and other dubious wikilinks

Y The wikilinks report shows 1 link to a DAB page, but it's the "For other uses" item at the top, so that's OK. --Philcha (talk) 07:49, 12 June 2009 (UTC)[reply]

I'm reluctant to do this unless it's essential. No images sandwich text, except the first, which must go in taxonomy, and none overlap sections, at least on my thumb sizes. If I have to take out images, some of the remainder will face out of the text or not conform with layout guidelines, either way it would be picked up at FAC as a breach of MoS. Unless you view this as a deal breaker, I'd rather leave as it is and take my chances at FAC jimfbleak (talk) 12:46, 12 June 2009 (UTC)[reply]

Done "Predators of chicks and eggs include mammals such as foxes, feral cats and stoats, ..." is inconsistent with section "Nesting and survival", where "Predators of waders breeding in wet grasslands include birds such as large gulls, Common Raven, Carrion and Hooded Crows, and Great and Arctic Skuas; foxes occasionally take waders, and the impact of feral cats and stoats is unknown". --Philcha (talk) 08:10, 12 June 2009 (UTC)[reply]

I moved it out to the "Relationships with humans" section, and then decided to completely delete it, as there are a lot of birds on stamps and it may not be significant in itself. But it could be restored if needed, if it is thought to reflect anything important about the birds. Snowman (talk) 10:47, 12 June 2009 (UTC)[reply]
