Lewis’ Woodpecker 235 
Woodpecker. The flight is undulating and charac- 
teristic and the cry a loud “ Tchur, tchur.” 
The nest-site is sometimes a natural hole, sometimes 
excavated by the birds in a semi-rotten tree, either a 
pine, willow or cotton-wood; the entrance is narrow, 
only about an inch and three-quarters in diameter, 
and the eggs are laid upon the wood chips. These are 
five to seven in number, short, ovate and glossy-white, 
and average ‘99 x ‘76. Gale considered it one of the 
latest breeders, and found fresh eggs from June 10th 
to July Ist ; and there is a set of seven eggs, taken June 
16th near Greeley by I. C. Hall, and presented to the 
Colorado College Museum. 
McGregor obtained a curious clutch of ten eggs, varying 
from normal size to the size of a song-sparrow’s, in Weld 
co., on Crow Creek. The smallest egg was quite fresh 
but the normal ones heavily incubated. 
Genus ASYNDESMUS. 
Resembling Melanerpes in general structure, but the wing somewhat 
longer, and folding almost to the tip of the tail, and the feathers of the 
under-parts of peculiar structure ; the barbs stiff, bristle-like and loose ; 
plumage glossy metallic-green above with a grey nuchal collar. 
Only one species; confined to western North America,
