The role of food limitation and predation on reproductive success of burrowing owls in southern California

Creator:

Haley, Katherin L

Abstract:

The temporal and spatial variation in reproductive success exhibited by burrowing owls (Athene cunicularia hypugaea) facilitates the testing of mechanisms influencing this parameter. I predicted that food supplementation would increase reproductive success through one of two means: (1) directly, through increasing food availability and decreasing the effects of brood reduction,...

Habitat selection, reproductive success, and site fidelity of burrowing owls in a grassland ecosystem

Creator:

Ronan, Noelle A.

Abstract:

I used a comparative and experimental approach to examine nest habitat selection, reproductive success, and nest site fidelity of burrowing owls (Athene cunicularia) in a large, non-fragmented grassland in southwest California. In 1999, I compared habitat characteristics between nest sites (n = 31) and randomly selected, unoccupied burrows (n =...
