Association of Sex, Fledging Date, and Sibling Relationships with Post-Fledging Movements of Burrowing Owls in a Nonmigratory Population in the Imperial Valley, California

Creator:

Catlin, Daniel H. and Rosenberg, Daniel K.

Abstract:

Natal dispersal is an important driver of population and colonization dynamics, yet factors that affect timing and distance of post-fledging movements are poorly understood. We studied post-fledging movements of 34 (12 male and 22 female) juvenile Burrowing Owls (Athene cunicularia) between June 2002 and April 2003, in a nonmigratory population...

Influence of Food Limitation on Reproductive Performance of Burrowing Owls

Creator:

Haley, Katherin L. and Rosenberg, Daniel K.

Abstract:

Reproductive strategies of birds are shaped by patterns of food supply, yet empirical evidence of the consequences and mechanisms of food limitation on reproductive performance is inconsistent, probably due to variable responses from species of differing life-history strategies. We tested the hypothesis that food supplementation would increase reproductive rates of...
