DIVERS, GREBES, AND CORMORANTS. 169 
Examples occasionally occur on our eastern and 
southern coasts especially, but the bird is too rare 
to form any feature in the ornithology of the 
British seaboard. It may be readily distinguished 
from the other European Grebes by its decidedly 
up-curved bill, and by the large amount of white 
on the primaries and secondaries. In the nuptial 
plumage the head and neck are black. In its 
habits generally it differs little from the other 
species. 
SCLAVONIAN GREBE. 
Along the eastern coasts of England, and round 
most of the Scottish littoral, as well as off Ireland, 
this species, the Podicifes cornutus of most 
naturalists, is of tolerably frequent occurrence 
during winter. It requires all the skill of an 
expert ornithologist to distinguish this Grebe in 
winter plumage, so closely does it resemble the 
Red-necked species. It is a shorter winged bird, 
and has the three outermost secondaries dusky 
brown, instead of white, as in that bird, whilst the 
previous species is always distinguishable by its 
up-curved bill. There is nothing in the habits 
of this Grebe to call for special remark: it keeps 
exclusively to the water, dives to escape danger 
and to capture prey, and swims beneath the surface 
as adroitly as a frog. The Sclavonian Grebe is 
a wide ranging species, inhabiting during summer 
the Arctic and sub-Arctic regions of Europe, Asia, 
and America, retiring southwards in winter. This
