BUTTON'S Vireo is one of the three species which Mr. 

 Cassin added to the genus in 1851, and a very near 

 relative of V. noveboracensis and V. modestus. It was originally 

 described from Monterey, and has since been found to extend 

 on the one hand into certain portions of California, and on the 

 other to Guatemala. It is also cited from various localities in 

 Mexico, where it is stated to reside, according to Sumichrast, 

 in the Alpine region of Orizaba. I have never seen it alive, 

 and have no information to offer respecting its habits. A 

 memorandum of Mr. Xantus's is quoted by Dr. Brewer, to the 

 effect that a nest containing incubated eggs was found early in 

 May at Fort Tejon suspended from three high weed-stems, a 

 foot from the ground. Dr. J. G. Cooper has found this bird 

 wintering in California up to 38, and supposed it to go further 

 north in summer, as he observed but few on the Coast Range 

 in May. One that was shot by him at San Diego on the 9th 

 of May contained an egg ready to be laid. His observations, 

 as for as they go, indicate a bird whose habits, as might be 

 expected, are much the same as those of the White-eyed Vireo.
