Lenst Flycatcher 



White 



466a. Alper Flycatcher. 



Empidonax trailli alnorvm. 



Range. — United States, east of thp Mississippi 

 and north to New Brunswick. 



The only difference between this and the pre- 

 ceding variety is in the more greenish upper 

 parts. They are quite abundant in the breed- 

 ing season from New England and northern 

 New York northward, frequenting, to a great 

 extent, alder thickets bordering streams. Their 

 nests and eggs do not differ appreciably from 

 those of the western variety of Traill Fly- 

 catcher. 



467- Least Flycatcher. 

 "Empidonax minimus. 



Range.- — North America, east of the Rockies 



and north to the interior of Canada, wintering 



south of the United States. 



These little birds (5.5 inches 

 long) are common about houses 

 and orchards on the outskirts of cities, and on the edges of for- 

 ests or open woods. They are very frequently known by the 

 name of Chebec from their continually uttered note. In nearly 

 all instances, the nests are placed in upright forks at elevations 

 varying from four to twenty-four feet from the ground. The 



nests are made chiefly of plant fibres, fine grasses, string, cobwebs, etc., and 



the three to five eggs are pale creamy white; size .65 x .50. 



168. Hammond's Flycatcher. Empidonax hammondi. 



Range. — North America, west of the Rockies and from British Columbia south- 

 ward, wintering south of the United States. 



This western representative of the Least 

 Flycatcher is loss abundant and more shy, 

 but has the same nesting habits as the east- 

 ern birds, placing its nests either in upright 

 crotches or. more rarely, upon horizontal 

 branches at a low elevation. The eggs can- 

 not be distinguished from those of t lie last 



species. 



Mif). Wright's Flycatcher. Empidonax wrighti. 

 Range. Western United States, breeding from the Mex 



ican border to Oregon and wintering south of the United 



States. 



A very similar bird to the last hut whiter 

 below. It is a much more abundant species 

 than the last and is found breeding In open 

 woods and thickets on all (lie ranges. TIip 

 nests are built like those of the Least Fly- 

 catcher and nearly always are found in 

 the crotch of trees or bushes at a low pIp 

 ation; their nests, like those of thP two 



preceding species, hear a Btrong resemblance to those of 



thp Yellow Warblers which are found in the same local! 



ties and locations. The eggs are pale creamy whltp. four 



in number and measure ,RS x .52.
