VlREONIDAE 



VIREOS 



The Vireos are small insect-eating birds, yet 

 larger than the warblers, with slender beaks and 

 greenish gray plumage. They frequent the outer 

 branches of deciduous trees, yet keep well hid- 

 den among the leaves, singing as they work. 

 Some of the species are good singers, all have 

 a petulant call note like the word min-u-eet' . 

 They build a neat cup-shaped nest, hung from 

 a crotch in a twig.
