SCLAVONIAN OR HORNED GREBE 



Podiceps cornutus {Gmeliii) 



The Sclavonian Grebe is a northern species, and is a strag- 

 gling autumn and winter migrant to the British Islands. It 

 inhabits the Northern Nearctic and Palsearctic regions, and 

 visits our shores, especially in the east, annually. In the 

 north of Scotland it is quite common. Ireland is also regularly 

 visited on migration by it every year. 



In summer the upper parts of the adult male are dark 

 brown ; the crown, forehead, chin, and neck-ruff black, and 

 a tuft of elongated feathers on each side of the head chestnut ; 

 upper plumage, deep brown. Secondaries white, except the 

 three outer ones, which are dusky like the primaries ; neck, 

 breast, and flanks yellowish chestnut ; remainder of under 

 parts white. In winter the crest is absent ; the under parts 

 are white. The young resemble their parents in winter 

 dress. Length from 12 to 13 in. ; wing 5-5 in. 



BLACK-NECKED OR EARED GREBE 

 Podiceps nigricollis (C L. Brehm)

The adult in spring has the head and neck black with 

 a triangular patch of yellowish chestnut feathers on the ear- 

 coverts ; upper parts dark brown ; under parts white ; flanks 

 chestnut. All the secondaries white, and the four innermost 

 primaries also show much white. Bill black and slightly re-
