BLACK-HEADED GROSBEAK. 
596. Zamelodia melanocepliala. 7% inches. 
This species similar in size to the Rose-breasted Grosbeak 
of the eastern sections (which is sometimes found west to 
Colorado), does not have the bright colors of his eastern 
brother. In habits they appear to be much the same, their 
song is wonderfully sweet and clear. They are very quiet 
birds, and when nesting will almost allow one to touch them 
before leaving. Their nests are simply a few straws and sticks, 
loosely laid on the forks of some horizontal branch of a bush 
or low tree, so frail that frequently their eggs can be seen 
from beneath. They lay four eggs of a bluish green, spotted 
and blotched with different shades of brown (1.00 x.70). 
WESTERN BLUE GROSBEAK. 
597a. Guiraca ccerulea lazula. 7 inches. 
Found more in the open woods, in small groves and along 
the roadside in the small brush. It seems out of place to have 
three members of the same family with such a diffeience 
of plumage. One with rose, white and black; the next with 
black, brown and yellow; and this bird, a blue and blac c. 
Their nesting habits and also their eggs are much the same 
as above, the eggs being a little smaller (.85 x.62).
