The northern giant hummingbird (Patagona peruviana) is the largest species of hummingbird and one of two species of the genus Patagona.[2]
It and the sympatric southern giant hummingbird (P. gigas) were once considered the same species, i.e., the giant hummingbird, though some researchers have already classified them as different species or subspecies in the past.[1][2] Genomic analysis supports the separation of the two species which shows that they diverged between 2.1 and 3.4 million years ago, in the late Pliocene.[4] Williamson and colleagues attributed the binomial name Patagona chaski to the northern giant hummingbird in 2024,[4] but this taxon was already described as Patagona peruviana by Boucard in 1893, so P. chaski is a junior synonym of P. peruviana.[1][2]
A single F1 male hybrid between the two species has been recorded in a study that collected a sample of 101 individuals, suggesting that hybridization occurs regularly between the species. However, high genome-wide FST between the two species shows that introgression and backcrossing of first generation hybrids occurs very rarely in nature, such that there is no gene flow occurring between the two species.[4]
