Nesting success of Dusky Canada Geese (Branta canadensis occidentalis) has declined greatly since a major earthquake affected southern Alaska in 1964. To identify nest predators, we collected predation data at goose nests and photographs of pred[...]

Roost counts may be a useful method for assessing and monitoring parrot populations as long as counting regimes can detect real differences in abundance above the noise of daily variability in roost size. We studied a roost of up to 85 Red-taile[...]

Thick-billed Parrot (Rhynchopsitta pachyrhyncha) nest sites were studied during a six-year period (1995-2000) at six nesting areas in the Sierra Madre Occidental in Mexico. Nests were found in 187 snags or live trees of seven species, which aver[...]

We describe the nest-site characteristics of Northern Waterthrushes (Seiurus noveboracensis) in western Newfoundland. Based on data for 36 nests (20 in streambanks, 16 in overturned trees) and 108 comparative sites, we examined habitat features [...]

Locating and monitoring nests are among the most widely used approaches in studies of avian ecology, evolution, and conservation. While several papers outline "best practices" for nest studies, nest-searching techniques are seldom standardized i[...]

We studied the gonadal and molt cycle of three species of Columbina ground-doves in seasonal savannas of Venezuela to explore whether gonadal development is related to seasonal patterns of rainfall. The study site is a strongly seasonal, open wo[...]
