GREBES 
sight on the open waters of the lake. They nest in colonies often con- 
taining hundreds of pairs, and I have known them voluntarily to spend 
much time away from their nests, leaving the eggs uncovered. I have 
also seen the bird while standing nearly erect in the nest place some 
covering over the eggs before sliding into the water at my approach. 
Thousands of these birds have been killed for their breasts by millinery 
collectors.

Although this large Grebe breeds in reed-grown lake borders, at 
other seasons it frequents large bodies of open water, and in winter 
resorts to the sea, where I have seen it fifty miles from land. So far as 
my experience goes it thoroughly covers its eggs, even when frightened 
from the nest, and although making every effort to avoid being seen, 
remains near its home, uttering a sharp explosive cluck of protest. 
Brewster describes its call as deliberately uttered and exceedingly 
loud and harsh, not unlike the voice of an angry Crow, but with much 
greater volume.
