Capsule The presence of Ferruginous Pygmy Owls Glaucidium brasilianum breeding in the xerophytic forest of Caldén Prosopis caldenia in central Argentina was slightly affected by forest maturity but neither by the structure ...

We studied how human induced structural changes in forests affect stand use of the Rufous-legged Owl (forest-specialist) and the Austral Pygmy Owl (forest-facultative), in a gradient from lowland disrupted forests to ...

The Ferruginous Pygmy-Owl (Glaucidium brasilianum) has a broad geographic distribution, occurring from the southwestern United States to Central America and South America (Holt et al. 1999, Proudfoot and Johnson 2000).

Forested landscapes vary greatly in habitat structure and complexity due to natural and anthropogenic disturbances that may alter forest attributes. Habitat structure along with temporal factors may directly affect ...

Concentrations of organochlorine pesticides were quantified in samples of feathers (n = 17) and blood (n = 15) of the ferruginous pygmy owl (Glaucidium brasilianum). The individuals were captured near the Protected Natural ...

Habitat-specialists have narrower niches, but achieve higher or similar peak performance (e.g. occurrence probability, psi) than habitat-generalists along resource gradients that may be selected from the stand- to ...
