DERBY FLYCATCHER 



This is a non-migratory species ranging throughout most of Central America 

 and extending north to the valley of the lower Rio Grande, in Texas. 



BEARDLESS FLYCATCHER 



A species principally of Central America, from Nicaragua northward, that 

 spends the winter at least as far north as central Mexico. A few have been noted 

 in southern Texas, where the species arrives in March. The bird breeds 

 near Tucson, Arizona; here the first one was noted April 28, 1881, fledged 

 young were seen Mav 29, 188 1 and young in the wing, but still fed by the parents, 

 June II, 1903. 



OLIVE-SIDED FLYCATCHER 



The Olive-sided Flycatcher occurs throughout the United States except in 

 the southeastern part, where it is almost unknown outside of the mountains. 

 Though it breeds in the mountains as far south as North CaroHna, records of 

 its movements are rare south of New England.
