This weU-known bird is very common in Mexico and Central America during the 

 winter months, all or nearly all the specimens migrating to North America in the 

 spring, and remainmg there to breed. In September and October de Oca says^^ 

 T. colulris is very common at Jalapa and Coatepec as well as in the Valley of Mexico 

 where it may also be seen in November. M. Boucard also speaks of its abundance in 

 Mexico, but he says that a few individuals remain to breed. This statement is 

 confirmed to some extent by specimens obtained by Mr. Eichardson in the State of 

 Tamaulipas in the successive months of March, April, and May, at which time it also 

 occurs on the north side of the mouth of the Eio Grande in Texas. Villada ^'^ also says 

 a few individuals remain to breed in the Valley of Mexico, and he describes the nest 

 in some detail. 



In its southern migration it spreads to Nicaragua, Costa Eica, and Chiriqui, but in 

 much diminished numbers, and it does not seem to pass beyond the last-mentioned 

 district. 



During its stay in the south, T. colubris is found at all altitudes from the sea-level at 

 Tampico and in Yucatan to as high as 8000 feet in the Valley of Mexico.
