From October 1994 to November 1995 the behaviour, postures and diurnal activity of tive captive squirrels Sciurus ingrami were observed and registered. Four basics postures, five grooming behaviours, displacements and face wiping behaviour were identified. Based on behavioural observations, the diurnal activity was divided into four categories: resting, displacement, teeding and maintenance. The time spent in each category varied seasonally and the squirrels spent more time resting during winter and spring. However, more time was spent feeding during autum and summer and was reduced the displacement in autum. Two types of breeding behaviour were identified: sexual trailing and mating chase of females by males. However copulatori behaviour was not recorded during the studied period. We also verified that S. ingrami presents thermorregulation behaviour during winter, remaining resting in the nest to conserve energy in heath maintenance. During the hottest seasons, the squirrels remain resting out of the nest, placed on the branchs to decrease their body heat to normal temperature, The behaviours observed in this study were similar to those described in the literature, as well as the mating behaviour, which was very similar to S. carolinensis.
