Abstract

Agonistic behaviour of Gila Woodpeckers (Centurus uropygialis), including vocalizations, visual displays and other related behaviours, is described. Aggressive interactions with both con- and hetero-specifics were analyzed by stochastic processes. Results indicate that Gila Woodpeckers are far less aggressive than qualitative descriptions suggest and reasons for this discrepancy are presented.

The ecological correlates of Gila Woodpecker aggression were investigated and it appears that most aggression is related to defense of areas both intraspecifically and interspecifically. The effects of the two types of territoriality on the distribution of the species involved were compared and found to be significantly different. A model is presented to explain how an individual can defend more than one territory which overlap in time and space.
