The first specimens of this bird that reached Europe were those obtained by Col. 
Velasquez in Guatemala, and described by Prince Bonaparte in 18371. The bird is 
now known as an inhabitant of the hot forest region of the whole of Central America, 
beyond which area it reaches the middle of the Mexican State of Vera Cruz in one 
direction and the northern part of Colombia in the other, being nearly everywhere 
tolerably abundant. It is absent from Western Mexico, but occurs on both sides of 
the mountain-range of Guatemala. It is only in Costa Rica that this bird seems to be 
rare, for though we have a specimen from Bebedero in that country !4, it appears from 
Mr. Zeledon’s most recent list of the birds of Costa Rica that only a Guatemala 
example of &. rufiventris exists in the National Museum of Costa Rica. 
Mr. Nutting 1° 1” obtained his specimens in dense forest, and he tells us that these 
birds climb about trees like Nuthatches (Siéta). Salmon says ® that the iris in life is 
red, and that this bird feeds on insects and builds its nest in low bushes. He does 
not, however, tell us how the latter is constructed, nor give us any information about 
the eggs. 
Stolzmann, writing of the closely allied &. albiventris, says that the only specimen 
he shot at Yurimaguas was in the top of a low tree in the forest, its movements 
recalling those of a Polioptila.
