Willow Warbler

Phylloscopus trochilus

Locally very common Summer visitors from April-October with 2 million breeding pairs in Britain plus 1-6 million birds in Ireland.

Also breeds in mainland  Europe.

Winters in tropical & South Africa.

They are greenish brown above and off-white to yellowish below; the wings are plain greenish-brown with no wingbars.

Juveniles are yellower below than Adults.

It is very similar to the Chiffchaff, but non-singing birds can be distinguished from that species by their paler pinkish-yellow legs (dark brown to blackish in Chiffchaff).

Its song is a simple repetitive descending whistle, while the contact call is a disyllabic 'hoo-eet', distinct from the more monosyllabic 'hweet' of Chiffchaffs.
