Pouillot à grands sourcils

Phylloscopus inornatus

Petite fauvette active avec des parties supérieures verdâtres, des parties inférieures blanches, un sourcil jaunâtre pâle distinct et des barres alaires pâles distinctes (la barre alaire supérieure est courte et moins distincte). Chevauche l'aire de répartition de nombreuses autres espèces de fauvettes ; à comparer notamment avec la Fauvette de Hume (Hume’s Warbler), le Pouillot de Pallas (Pallas’s Leaf Warbler) et le Pouillot à deux barres (Two-barred Warbler). Se reproduit dans les forêts de moyenne à haute altitude et hiverne dans une large gamme d'habitats boisés et broussailleux, où elle est généralement assez active ; plane parfois pour cueillir des insectes au bout des feuilles. Son cri est un « tsu-weet » distinctif, de deux syllabes, ascendant. Son chant est une série très aiguë et fine de notes alternant longues et courtes : « tseee-ts’a’wi-tseeeee ».

Identification

This is one of the smaller Old World warblers, at 9.5–11 cm long and weighing 4–9 g distinctly smaller than a chiffchaff but slightly larger than Pallas's leaf warbler. Like many other leaf warblers, it has overall greenish upperparts and white underparts. It also has prominent double wing bars formed by yellowish-white tips to the wing covert feathers (a long bar on the greater coverts and a short bar on the median coverts), yellow-margined tertial feathers, and long yellow supercilium. Some individuals also have a faint paler green central crown stripe though many do not show this.<p>It is not shy, but its arboreal life style makes it difficult to observe. It is almost constantly in motion. Its song is a high-pitched medley of whistles; the call is piercing, often disyllabic "tseeweest", strikingly loud for the bird's small size. The only real possibility of confusion is with the similar-looking Hume's leaf warbler (P. humei), which in the limited area of overlap has duller colours, a faint second wing bar and dark legs and lower mandible. Their songs and calls are clearly distinct, with Hume's having a more chirping "chwee" call. It can easily be distinguished from Pallas's warbler as it does not have the conspicuous yellow central crown stripe and rump patch shown by that species.

Taxonomie

The yellow-browed warbler was first described by the English zoologist Edward Blyth in 1842 and given the binomial name Regulus inornatus. The current genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific inornatus is Latin for "plain".
