Phoebe 



4-56. PHCEBE. Sayornis phoebe. 



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 eggs 

 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.
