warbler " is strongly migratory and the majority of the population winters in sub-SaharanAfrica . It is one of the first leaf warblers to return in the spring but is later than theChiffchaff , "Phylloscopus collybita".This is a
bird of open woodlands with trees and ground cover for nesting, includingbirch andwillow uplands. The nest is built in close contact with the ground, often in low vegetation. Like most Old World warblers, this smallpasserine isinsectivorous .This is a typical leaf warbler in appearance, greenish brown above and off-white below. It is very similar to the Chiffchaff, but non-singing birds can be distinguished from that species by their paler legs, longer paler bill, more elegant shape and longer
primary projection . Its song is a simple repetitive descending whistle.References
