Seasonal decline in breeding performance of the Kelp Gull Larus dominicanus
(Pacific Seabird Group, 2008-12)
The effects of timing of breeding on reproductive parameters of Kelp Gulls Larus dominicanus were studied in Patagonia, Argentina, during 1998 and 1999. Yearly and spatial variation in the study were assessed by sampling ...

Differing nest-defence behaviour in urban and rural populations of breeding Burrowing Owls
(Csiro Publishing, 2016-04)
The behaviour of birds in urban habitats often differs from that of birds in surrounding natural and rural habitats, with the attenuation of fear responses to humans a primary behavioural adaptation to urban life. In ...
Nest reuse by Pale-breasted Thrushes reduces the chance of cowbird parasitism and allows earlier initiation of breeding
(Wiley-Blackwell, 2021-05-04)
Selection of safe nest sites is a first step toward improving the chances of breeding successfully. Reusing old nests can save time and energy for breeding birds, but nest reuse is rare among open-cup nesting songbirds and ...
Reproductive Success of the Creamy-Bellied Thrush in a Southern Temperate Zone
(Wilson Ornithological Society, 2012-03)
We describe the breeding biology and reproductive success of a Creamy-bellied Thrush (Turdus amaurochalinus) population from a southern temperate zone in western Argentina. We found 236 Creamy-bellied Thrush nests of which ...
Weather and agricultural intensification determine the breeding performance of a small generalist predator
(Nature, 2020-12-12)
Land-use changes due to agricultural intensification and climatic factors can affect avian reproduction. We use a top predator of agroecosystems, the American kestrel (Falco sparverius) breeding in nest boxes in Central ...
