Abstract: | The role of prior experience in nest-site selection by a long-lived corvid, the pinyon jay, Gymnorhinus cyanocephalus, was investigated. The major sources of nest failure were loss to avian predators (Corvus corax and Corvus brachyrhynchos) and abandonment after cold and snowy spring weather. Cold weather favours exposed nesting because solar radiation reduces the energetic costs to nesting females and quickly melts snow in and around the nest. Predation favours cryptic nests. The relative height at which individual jays nested (an index of nest exposure) was compared to their previous nest height and to the fate of that nesting attempt. For the following reasons jays appear to associate nest exposure with the fate of a particular nesting attempt: (1) after nesting in exposed sites, subsequent nests were 27 |
