Factors affecting within-season and between-season breeding dispersal of burrowing owls in California

Creator:

Catlin, Daniel H.

Abstract:

Dispersal is integral to our understanding of the life history and population biology of many vertebrates, but difficulties in detecting long distance movements have complicated its study. Moreover, studies of factors affecting dispersal are often unable to determine the relative contributions of variables such as nesting success, mate fidelity, and...

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 =...
