Ethogram of Eira barbara in captivity. An ethogram was described and the qualitative and quantitative effects of gender differentiation was analyzed for a male and female Eira barbara (Carnivora: Mustelidae) in captivity. The study was carried out at the Dois Irmãos Zoological Park in Recife, PE Brazil, from April to October, 2005. Observations were made from 07:00h to 17:00h. An ad libitum method was followed for ethogram building, and instantaneous scan sampling for systematic observations (total of 100h observation time). Behavioral categories were grouped into two divisions, individual (40 categories), separated into seven subdivisions; and social (18 categories) separated into two subcategories. Behavior patterns that were exclusively or preferentially exhibited by the male included: attempting to copulate, carrying, grasping, vocalizing, and urinating on; the female’s main behavior categories included: to be carried, attempting to grasp, genital scent marking, getting wet, playing, hunting, carrying the feeding bowl and growling.
