" 'On the next two days, I passed by the spot where I had heard the 

 warbler singing, on the way to and from my botanical collecting 

 ground. Morning and afternoon, I heard the same voice in the same 

 part of the coffee plantation, where the bird seemed to have fixed his 

 residence.' 



"Yellow warblers may sing in Central America in the spring as well 

 as the fall. Last year, the male yellow warbler that wintered about 

 my house in Costa Kica sang briefly in the early morning from April 

 12 to 24. After April 28, I saw no more of his kind in the vicinity. 



"From November 1936 until February of the following year, a 

 yellow warbler slept every night in a bush of Hibiscus mutabilis 

 beside my cabin in Rivas, Costa Rica. He rested upon one of the long 

 leaf-stalks, where the broad blades of the higher leaves formed a 

 roof above him, but he was exposed on the sides and easily visible 

 from the ground. He always slept alone. 



"Early dates of fall arrival in Central America are: Guatemala — 

 passim (Griscom) , August 9 ; Sierra de Tecpan, 8,500 feet, September 

 4, 1933 ; Huehuetenango, 6,500 feet, September 11, 1934. Honduras —

 11, 1942. Panama — Canal Zone (Arbib and Loetscher), August 22, 

 1934.

Todd and Carriker (1922), reporting for the Santa Marta region 

 of Colombia, say that the eastern yellow warbler is "a common winter 

 resident throughout the whole of the lowlands and lower foothills, 

 but rare above the coastal plain. It frequents shrubbery, open ground 

 with scattering bushes, the low growth along the banks of streams 

 and the sea-beach, etc. — the same kind of covert in general to which 

 it is so partial in the breeding season."
