Pallas’s leaf warbler is one of the smallest Palearctic warblers, with a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars, supercilia and central crown stripe. The female builds a cup nest in a tree or bush, and incubates the four to six eggs, which hatch after 12–13 days. The chicks are fed mainly by the female and fledge when they are 12–14 days old.
About Pallas’s leaf warbler in brief
Pallas’s leaf warbler is one of the smallest Palearctic warblers, with a relatively large head and short tail. It has greenish upperparts and white underparts, a lemon-yellow rump, and yellow double wingbars, supercilia and central crown stripe. The female builds a cup nest in a tree or bush, and incubates the four to six eggs, which hatch after 12–13 days. The chicks are fed mainly by the female and fledge when they are 12–14 days old. Pallas’s Leaf Warbler is insectivorous, feeding on the adults, larvae and pupa of small insects and spiders. It is strongly migratory, wintering mainly in south China and adjacent areas of southeast Asia, although in recent decades increasing numbers have been found in Europe in autumn. Its numbers are believed to be stable and it is evaluated as of ‘least concern’ by the International Union for Conservation of Nature (IUCN) The English name commemorates the German zoologist Peter Simon Pallas, who found it on the Ingoda River in Siberia in May 1772. The nominate form P. p. proregulus breeding in northern Asia, and other subspecies breeding much further south at high altitudes in the mountains from the western Himalayas east to western China.
DNA analysis from 2006 has confirmed these forms to be sufficiently distinct that they are now treated as separate species. The breeding ranges of the Gansu leafbler and the Chinese leafbleransu, but the species are separated ecologically: the southern warbler uses taller forest habitats, the Chinese warbler rumped up scrubby habitats and the Lemon-rumped warbler uses lower forest habitats. The species’ former subspecies appears to have diverged from the Chinese leafbler 4–5 million years ago, and from its former subspecies about 1.5million years ago. The current genus name Phylloscopus is from Ancient Greek phullon, ‘leaf’ and skopos,’seeker’ The species was sometimes used as a synonym for Pallas’s leafbler, but this is no longer used by the IUCN as it is now a monotypic taxon. It was formerly part of the Old World warbler family Sylvidae, but has now been split off as a separate family, the Phylloscopidae.
