LLWolf 1963 Amphitula rufocens August 2 20 mi.SE Morelia, Michoacan, Mexico Very little continuous singing by ♂♂. Usually at most 2-3 minutes. ♂♂ are spaced in oak woodland (open) + shrubby 2nd growth. Birds are corn. Saw no family groups or young birds, so apparently breeding is just beginning. August 3 20 mi.SE Morelia, Michoacan, Mexico ♂ on hill above camp sang long bout of songs at ~0630. By time I got up there recorder had quit. During wait saw bird fly in to oak about 20 feet up. Then cross to another oak + dive down into gully from whence immediately issued a chattering series similar to but less loud & less intense than pair reunion duet of Brown Towhees. Another time heard chattering call just over bank. As I approached pair of rufocens flew up from ground. Was able to follow bird + collect ♂ which has very edemorous brood patch. While recording a singing ♂ - probably same as bird in preceding paragraph - he flew to gully + I recorded immediately thereafter a chattering series. I would guess that it is a duet, but have yet to actually see the birds engaged in the chattering. This same male was singing on the hillside when a series of chattering issued from gully. Immediately he stopped singing & flew over to brink of gully just above site of chattering.
