PERCHING BIRDS 



454b. Lower California 

 Flycatcher. Myiarchus 

 cinerascens pertinax. 



Range. — Lower California. 



This sub-species is similar 

 to Nutting Flycatcher but pal- 

 er below and grayish above. 



455a. Olivaceous Fly 

 CATCHER. Myiarchus 

 lawrencei olivascens. 



Range. — Western Mexico, 

 north to southern Arizona. 



This is the smallest of the 

 genus found in the United 

 States, being but 7 inches in 

 length. Except for size it is 



Buffy 



similar to criiiitus but with 



very little, if any, rusty brown 



on tail, except for a slight 



edging on the outer web. 



Their nesting sites are the 



same as those chosen by the other Crested Flycatcher, but their eggs appear 



to have but little of the scratchy appearance of the other members. They are 



pale buffy, speckled and spotted with brown and lilac; size .80 x .60. Data. — 



Toluca, Mexico, May 20, 1895. Nest of brown hair and feathers, in hole in tree 



in woods. Collector, Fred T. Francis. 



Phoebe 



■i-.iC). Pn(p:BE. S(ii/u7-nis jjhahe. 



Range. — North America, east of the Rockies and north to Nova Scotia. 



These very common, grayish colored birds are very often known as "Bridge 

 Birds" because of the frequency with which they construct their nests under 

 bridges and arches; they also build in crevices in ledges or 

 among the hanging roots near the tops of embankments, and on ^-~-^, 



the rafters or beams of old buildings. The nests are made of 

 mud, moss and grass, lined with feathers. The four or five eggt; 

 measure .75 x .55. Occasionally, eggs will be found that have 

 a few minute spots of reddish brown. Freak situations in which 

 to locate their nests are often chosen by these birds, such as white 

 the brake beam of a freight car, in the crevices of old wells, hen 

 houses, etc. The birds are one of the most useful that we have;, being very 

 active and continually on the alert for insects and beetles that constitute their 

 whole bill of fare.
