148 PASSERES : Perching Birds 



BLACK PHOEBE 



(458. Sayornis nigricans) 7 in. 



Slaty black, with white belly and under tail-coverts. Crown 

 feathers lengthened, forming a decided crest. 



Immature: Black parts washed with brown, except head; a 

 rusty wing-bar. 



No other of our Flycatchers is so well known or so familiar in 

 its habits as this species. Generally fearless of mankind, its 

 sprightly "hip" as it darts after an insect, or returns to its perch, 

 makes it a favorite everywhere. 



OLIVE-SIDED FLYCATCHER 



(459. Nuttallornis borealis) 1\ in. 



Slaty brown above; tail and wings blackish, wing-coverts and 

 tertials light-edged; below, middle line of body white or yellowish, 

 from chin to tail; otherwise grayish olive. 



A notably "chunky" bird for one of the Flycatcher tribe. Its 

 look-out perch is a dead tree-top. Fond of honey bees, though 

 too few in numbers to menace the industry. 



Calls, loud and varied, but not unmusical. 



COUES FLYCATCHER 



(460. Myiochanes pertinax pallidiventris) 1\ in. 



Grayish brown above; light olive-gray below, with whitish 

 chin and dull yellowish belly. A dull-colored, unattractive bird, 

 distinguished by its very lack of distinctive marks. 



Nature has given it, however, a very distinctive call a 

 clearly and plaintively whistled "Ho-say' Ma-ree'-a." This, 

 coming from a constantly shifting and unseen source, is a most 

 pleasing note.
