(Redirected from Eared Grebe)
Alternative name: Eared Grebe
Medium-sized grebe, length 28-34cm, wingspan 57cm.
Juvenile: Resemble non-breeding adult, but browner with cheeks tinged buff
Flight: Upperwing shows broad white trailing edge to secondaries but lacks white of forewing base seen in Slavonian.
At all seasons slightly upturned bill distinguishes from Slavonian and in non-breeding plumage the more diffuse border between dark and light on head is useful.
Dark of crown extends to well below level of eye and merges with grey ear-coverts thus less clearly demarcated compared to Slavonian.
 Similar Species
Widespread in the both the Old and New Worlds but with a more southerly range than that of Slavonian Grebe P. auritus. Migratory in northern parts of range.
Europe: Highly discontinuous breeding range but small populations persist in many Central and Eastern European countries. Largely absent from the north and west but there are small populations in Britain, central and eastern France, Belgium and central and southern Spain. Main range extends from Denmark and eastern Germany eastwards to the southern Urals and Caspian. Patchy range in the south-east with scattered populations in the Balkans and Turkey.
Main wintering range in Europe lies from southern Britain and the Netherlands south to Biscay and around much of the Mediterranean and Turkey. In recent decades has begun to winter regularly in the Canary Islands.
There are 4 subspecies:
Breeds on small and shallow, densely vegetated freshwaters, in Eurasia often in association with Black-headed Gulls. Breeding sites are frequently abandoned in favour of new sites for no apparent reason.
In winter on larger, more open freshwaters, estuaries and sheltered seas.
Breeding begins mid-April in south of range to June in north, probably year-round in Africa. Breeds colonially, nest is a low mound of vegetation anchored to emergent vegetation in shallow water. Eggs: 3-5 (rarely 2-8), whitish initially soon becoming stained (44 x 30mm). Incubated by both sexes but mainly female for 20-21 days. Young tended by both sexes but divide brood in later stages, young able to feed themselves at 14 days, independent at 21 days. Single-brooded, possibly double-brooded at times.
Aquatic insects and their larvae, small fish, amphibians and crustaceans.
A wide range of calls when breeding including a display trill, a whistling bidder-widder-widder and a low poo-eep. Alarm call is whit repeated 2-3 times.
