Song Thrush
Turdus philomelos
Smólach
The Song Thrush is perhaps Ireland's tiniest song bird. Its plumage is warm brown above, pale below, heavily speckled with black. The spots run into one another in dark blotches and streaks. The underwings are noticeably honey-coloured, sometimes visible in flight, and the call is a distinct 'tsip'. Song Thrushes are familiar garden birds, feeding on worms and grubs and using favoured stones as anvils' for breaking open snails.

Blackbird
Turdus merula
Lon dubh
The male Blackbird's matt black plumage and striking orange-yellow bill are so distinctive that it requires no further description. The brownish female is sometimes mistaken for a thrush because of its pale and speckled throat but the differences are obvious from close range. The male Blackbird is one of Ireland's best song birds. Its song is deeper, with Iess repetition, than that of the Song Thrush, but is nonetheless similar. The alarm call is all excited squawk.
