Sombre Tit (Poecile lugubris)
Lesser Black-backed Gull (Larus fuscus)
Like a Great Tit-sized Willow Tit. Dark bib very large much bigger. The hood is also extended, and covers more of the head than in Willow Tit, making the white cheeks very narrow and wedge-shaped. Bulky build, with broad head and strong bill. Told from Siberian Tit by complete lack of buff tones to underparts and flanks. Less acrobatic than other tits, and bill powerful enough to tear seeds apart like a finch.
Sound:Structurally resembling other tits call and song. Usually recognised by its distinct timbre. Its peculiar, rapidly modulated voice sometimes resembles a tit with added electronic effects. Call: a characteristic "tz tz chrrt", resembling the alarm call of House-sparrow.
