Phylloscopus soror
Rare visitor: recorded only occasionally in this country
Alström's warbler (Phylloscopus soror), or the plain-tailed warbler, is a species of Old World warbler in the family Phylloscopidae. It was first described in 1999. It breeds only in China and winters as far as Thailand, Laos, Cambodia and Vietnam. Its natural habitat is temperate forests. Habitat and migration Alström's warbler often forages in a low, dense growth of forests. (Wikipedia, general species account).
This bird is known to eat insects and catch prey during short flights. The bird is not currently globally threatened. This bird has a very large range and does not approach the potential of being a vulnerable species. The warbler typically breeds in warmer, temperate areas. These areas are found within evergreen broadleaf forest zones and lush undergrowth in mature forests.
