not less tlmii five in a sin<.;le day, and very rarely weie any of them less 

 tluiu sixty feet from the ground. Dr. (icrhardt, wlio v as an accurate and 

 careful ()l).scrvor, speaks of these as the best huilt nests he had met witli in 

 tliis country, botli in ri'jj;ard to strength and its ingeniously contrived a])er- 

 ture, so narrowed at the top that it is impossible for the eggs to roll out even 

 in the sc orest wind. Tliey have two broods in the season in the Southern 

 States, one in April and again in July. 



This Flycatcher lays usually fiv(i eggs. These are of a, short oval form, 

 somewhat pointed at one end and rounded at the otiier, and measure .5() 

 of fin inch in lengtli by .44 in breadth. Their gro.nid-color is a greeni.sh- 

 wliite, marked and dotted with small blotclies and spots of varying and 

 blending shades of reddish-brown, lilac, and slate.

This species difl'ers from /*. rarulfii, in having the ash above less bluisli, 

 especiiilly on tiie forehead ; the black su])erciliary streak is only a horizontal 

 bar, not reiicliing tlie 1)111, wliereas in cn'rii/ix it not only reaches tlie l)ill, 

 but idso extends across tlie forehead ; the light superciliary stripe is more 

 distinct. The tail is entirely diiferent, the latenil feathers being almost 

 entiftly black, instetid of the reveI^s(^ 



From immature s])ecimeiis of /'. nirlinnirti it may be distinguished by 

 larger size and purer white lower jtarts, ami greater amount of white on 

 outer wi'bs of lateiiil tail-featliers. 



llAItlTs. Ihit little is known in regard to the distrilaition or history of 

 this sjK'cies. It appears to be peculiar to Arizbna and Mexico. There is no 

 good reason to suppose thsit it ditVers nmteriidly in any of its habits from 

 the other s])ecies of this genus. Dr. Coojier, who observed tliis species at 

 Fort Mojave, states that it is a winter residdit of tliat region in small 

 numbers ; and, so far as lie observed, is undistinguisliable either in haliit or 

 general appearance from cither of the otlier s])ecies wliicli at that season 

 are also found there. Its cry of alarm resembles that of tlie common wren.
