270 Birds of Colorado 
Bendire describes a nest sent him by Denis Gale from 
Gold Hill, taken on July 7th, at about 9,500 feet. 
Genus MYIOCHANES. 
Flycatchers of medium or small size—wing 2-5 to 4-5, with a broad, 
flattened bill, the width of which across the nostrils is often % the 
length of the culmen; wing long and pointed, the outer primary 
always exceeding the fifth, often the sixth; tail slightly emarginate, 
plain coloured, from $ to | the length of the wing; feet very slender 
and small; tarsus about the same length as the culmen and generally 
exceeding the middle toe and claw; no conspicuous silky tufts on 
either side of the rump. 
A considerable genus of some seventeen species, spread over the whole 
of temperate and tropical America (except the West Indies); one 
species commonly occurs in Colorado.

Description.—Closely resembling the Western Wood-Pewee, but 
distinguished by the darker and more olive and less ashy shade of the 
back ; by the less extent of the dusky grey band on the chest, which is 
more or less interrupted in the middle so as to form two lateral patches ; 
and by the pale whitish colour of the lower mandible, which is pinkish 
in life, but usually has the extreme tip brownish. Length 5-50; wing 
3-30; tail 2-50; tarsus -40; culmen -50. 
The sexes are alike, and the young essentially similar to the 
adults. 
Distribution. Breeding throughout eastern North America, from 
Manitoba and Prince Edward Island southwards to Texas and Florida ; 
migrating southwards in winter through Mexico and Central America 
as far as Ecuador and Peru, and also to Cuba. 
The Wood-Pewee is common as far as the eastern border of the great 
plains, westwards of which (i.e. in western Kansas) it is rare. It has 
only once been met with in Colorado; Warren obtained a single 
specimen near Springfield, in the extreme south-east corner of the State, 
on May 12th, 1905.
