Fieldfare
Turdus pilaris
Sacán

The Fieldfare is about the size of the Mistle Thrush and is similarly proportioned. It is, however, a darker bird on the back, wings and tail. The head and rump are noticeably grey. The underparts are tinged yellowish, heavily speckled and blotched with black. In flight the underwings are shining white like those of the Mistle Thrush. The flight call is a distinctive “chack, chack”. Large flocks are found in stubbles and other fields during the winter. Fieldfares are abundant and widespread winter visitors from Scandinavia.
