Thrush calls

The female Robin gives a high begging call, "see", when off the nest, requesting food from the male (Apr, Norfolk).












Robin alarm call (Dec, Herts).













Robin whistle, the so-called hawk alarm. The call is ventriloquial, and often heard by agitated birds wanting to return to a nest (Apr, Herts).






The call may rise or fall (Dec, Herts).




Identical calls are given by Blackbird, this one hidden in a bush, shortly before dawn (Apr, Norfolk).





Blackbird calls at dawn, consisting of a quieter pok and louder pli pli pli (Dec, Suffolk).



Another example of these agitated calls, again at dawn (Dec, Herts).

pli











The calls often accelerate into a crescendo, especially by birds on short flights (Dec, Suffolk).


reduced time scale










Migrant Blackbirds have a trilled or sibilant call that is similar to the calls of Tree Creeper or waxwings,(Dec, Herts).


















The Redwing flight call, also given regularly by feeding flocks as a contact call, is similar to the Blackbird call, but is a finer buzz (Dec, Herts).












In this recording, the first flight call is a Blackbird, the second and third Redwing (Dec, Herts).





Redwings also have a Blackbird-like puk (Dec, Herts).














Harsh calls (alarm calls?) are also heard from Redwing flocks (Apr, Herts)






The flight call of Fieldfares is similar (flock of 50 in flight, Apr, Suffolk).






Song Thrush alarm call (Mar, Herts).


(May, Herts).


reduced time scale










Mistle Thrush alarm (Dec, Suffolk).












Redstart calls (June, Suffolk). The huit call is remarkably similar to the Willow Warbler alarm call.
