Microhabitat nest cover effect on nest survival of the Red-Crested Cardinal [PDF]
The Wilson Journal of Ornithology, 2012 Predation is the primary cause of nest failure of birds and factors affecting predation risk have shaped the evolution of avian life histories. We evaluated the influence of microhabitat vegetation cover on Red-crested Cardinal (Paroaria coronata) nest ...

Black Skimmer Nest Survival in Mississippi [PDF]
Waterbirds, 2008 The nest survival of the Black Skimmer (Rynchops niger) in coastal Mississippi was modeled to better understand their breeding biology and suggest management strategies for protecting nesting colonies. During the 2004 and 2005 breeding seasons a total of

Patch Size and Nest Density Influence Nest Survival [PDF]
National Quail Symposium Proceedings, 2017 Nest predation is the primary cause of avian nest failure and therefore an important driver of avian population growth. Studies indicate that landscape context plays an important role in nest success, and although this is widely attributed to changes in ...

Habitat selection and nest survival in two Great Plains shorebirds
Avian Conservation and Ecology, 2020 As breeding populations of many grassland bird species decline, assessments of breeding habitat selection and reproductive success can provide useful insight into breeding ecology to support conservation delivery.

Early nest initiation and vegetation density enhance nest survival in Wild Turkeys
Ornithology, 2023 The theory of adaptive habitat selection suggests resource selection by animals should reflect underlying quality, such that individual selection confers an adaptive advantage via increased fitness.

Eggs in the freezer: energetic consequences of nest site and nest design in Arctic breeding shorebirds [PDF]
, 2012 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

Optimizing Nest Survival and Female Survival: Consequences of Nest Site Selection for Canada Geese [PDF]
The Condor, 2007 AbstractWe examined the relationship between attributes of nest sites used by Canada Geese (Branta canadensis) in the Copper River Delta, Alaska, and patterns in nest and female survival. We aimed to determine whether nest site attributes related to nest and female survival differed and whether nest site attributes related to nest survival changed ...

Nest survival of the Snowy Plover Charadrius nivosus at Marismas Nacionales, Nayarit
Huitzil, 2022 Breeding habitat loss and nest predation are considered the main causes of Snowy Plover (Charadrius nivosus) populations decline worldwide. We evaluated the effects of season, nest age, distance to nearest vegetation patch, distance to nearest body of ...

Camouflage predicts survival in ground-nesting birds [PDF]
Scientific Reports, 2016 AbstractEvading detection by predators is crucial for survival. Camouflage is therefore a widespread adaptation, but despite substantial research effort our understanding of different camouflage strategies has relied predominantly on artificial systems and on experiments disregarding how camouflage is perceived by predators.
