465. Empidonax acadicus. (Gmel.) 

 ACADIAN FLYCATCHER. 



Probably more abundant than 

 is geierally known. ' 'This species 

 is not at all common near Council 

 BlulTs. In the spring- of '91 I 

 found in company with a fellow 

 collector, two sets, one of 

 two, and one of three eg-gs. 

 Altog-ether we took four nests 

 with eg-gs that season. All were 

 situated within a radius of one- 

 half mile, in a tract of upland 

 woods, sloping- down to deep val- 

 leys. Nests were suspended in 

 same manner as vireos, and g-en- 

 erally overhung- the side of a hill. 

 There was however one except- 

 ion. This nest contained 3 eg^g-s. 

 Nest in a tract of level hazel 

 brush in a shady valley. Com- 

 posed entirely of oak catkins with 

 a few horse hairs in linings . Every 

 season since I have spent days, 

 searching every piece of woodland 

 but failed to discover this fly- 

 catcher." (E. Irons.) "Common 

 summer resident from May 10, to 

 Sept. 15. Nests saddled into 

 horizontal fork with bottom pro- 

 truding- below. Very few or no 

 lichens used. Nests usually in 

 low bushes in heavy thicket, or 

 else heavy woods. "(.Lynds Jones.)

 in Je cl-^cn Cc. May breed, but 

 have never four d nests. Retiring-

 (H. J. Giddir.g-s.) "Summer

 ercbly common but a shy bird,

 All nests were in pussywillows

 Eggs creamy white, speckled or 

 v/reathed with light reddish 

 brown." (R. M. Anderson). 

 "First met this bird in '89 when 

 I took three nests from the same 

 hedge and undoubtedly from the 

 same birds. A fourth was found 

 later with young. The hedge 

 formed a hollow square. The 

 birds are very shy. Following 

 nests have been taken by me.
