Breeding productivity, nest-site selection and conservation needs of the endemic Turkestan Ground-jay Podoces panderi

Nest-site selection and productivity of Vesper Sparrows breeding in grazed habitats

Livestock grazing in the shortgrass steppe of the Intermountain region of British Columbia may have a negative impact on ground-nesting birds, but evidence of such an impact is lacking. We examined nestsite selection and productivity of ground-nesting Vesper Sparrows (Pooecetes gramineus) across sites with different grazing histories. From 2006 to 2008, we monitored Vesper Sparrow nests and mea...

Breeding Ecology and Nest-site Selection of Song Wrens in Central Panama

•We describe nest-site selection and report measures of breeding productivity from a population of Song Wrens {Cyphorhinus phaeocephalus) in central Panama. We studied 31 pairs from 1995 to 1998 and collected data on nest prédation from 1996 to 1998. Song Wrens are year-round residents that build breeding nests for reproduction and dormitory nests for roosting. Twenty-five of 50 Song Wren breed...

Eggs in the Freezer: Energetic Consequences of Nest Site and Nest Design in Arctic Breeding Shorebirds

Birds construct nests for several reasons. For species that breed in the Arctic, the insulative properties of nests are very important. Incubation is costly there and due to an increasing surface to volume ratio, more so in smaller species. Small species are therefore more likely to place their nests in thermally favourable microhabitats and/or to invest more in nest insulation than large speci...

Nest and nest-site reuse within and between breeding seasons by three neotropical flycatchers (Tyrannidae).

Nest and or nest site reuse within and between breeding seasons was reported by the Euler's Flycatcher (Lathrotriccus euleri), the Sepia-capped Flycatcher (Leptopogon amaurocephalus) and the Gray-hooded Flycatcher (Mionectes -rufiventris) in forest fragments from southeastern Brazil. Nest and or nest site reuse between some years was frequent within a single breeding season by the Sepia-capped ...
