Activity patterns of collared pratincoles Glareola pratincola in a breeding colony

Abstract

The collared pratincole Glareola pratincola is a declining wader species, but most aspects of its biology are poorly known. In this study, an attempt is made to characterize the basic behavioural repertoire of the species, searching for differences between sexes. Focal observations of the most common activities were obtained in a breeding colony in southwestern Spain. Pratincoles did not equally distribute their time among types of activity, but spent more time in alert behaviour than feeding and moving, and more time preening than moving in the colony site. Males devoted more time to vigilance for predators than females, and both sexes increased the time spent resting and decreased the time for vigilance as the breeding season progressed. These sex–related and seasonal effects on the vigilance behaviour suggest that competition for females and ambient temperature influence the daily activity pattern of collared pratincoles during breeding.
