Crippled Owl Nesting

The Nesting of the Great Horned Owl

ON March 19, 1926, the nest of a Great Horned Owl (Bubo virginianus pallescens?) was found in one of the thickly wooded canyons on the military reservation, Fort Riley, Kansas, which presented an unusual opportunity for intimate study of the nest life and growth of the young from very early in their life history until the leaving of the nest. The terrain consists of rolling grass-covered hills ...

Comparing food limitation among three stages of nesting: supplementation experiments with the burrowing owl

Food availability is an important limiting factor for avian reproduction. In altricial birds, food limitation is assumed to be more severe during the nestling stage than during laying or incubation, but this has yet to be adequately tested. Using food-supplementation experiments over a 5-year period, we determined the degree and timing of food limitation for burrowing owls (Athene cunicularia) ...

Herring Gulls Nesting in Artificial Goose-nesting Structures

Herring gull (Larus argentatus) nesting in artificial goose-nesting structures was documented at the Winous Point Shooting Club, Port Clinton, Ohio, 1974—78. Gulls and Canada geese (Branta canadensis) nested in 14—28% and 12—23% of the structures, respectively. Gulls nesting in the structures did not influence goose nesting. Clutch sizes and egg-laying dates were synchronous with other local po...
