Age-specific nest-site preference and success in eiders
Oecologia, 2009Variation in nest concealment is puzzling given the expected strong selection for safe nest sites. Selecting a concealed nest may decrease the risk of clutch predation but hinder parents from escaping predators, providing a possible solution to this paradox.

Intraseasonal patterns in shorebird nest survival are related to nest age and defence behaviour
Oecologia, 2010Nest survival may vary throughout the breeding season for many bird species, and the nature of this temporal variation can reveal the links between birds, their predators, and other components of the ecosystem. We used program Mark to model patterns in nest survival within the breeding season for shorebirds nesting on arctic tundra.

Development with age of nest box use and gregarious nesting in laying hens
Applied Animal Behaviour Science, 2010Abstract Use of nest boxes is an important part of the behavioural repertoire of laying hens kept under commercial conditions. A special form of nest box use is gregarious nesting, which occurs when a hen given the choice between an occupied and an unoccupied nest site chooses the occupied nest site.

Modeling Age and Nest-Specific Survival Using a Hierarchical Bayesian Approach
Biometrics, 2009Summary: Recent studies have shown that grassland birds are declining more rapidly than any other group of terrestrial birds. Current methods of estimating avian age‐specific nest survival rates require knowing the ages of nests, assuming homogeneous nests in terms of nest survival rates, or treating the hazard function as a piecewise step function ...

Predation on painted turtle nests: nest survival as a function of nest age
Canadian Journal of Zoology, 1982This study examined the relationship between nest age and predation rate in painted turtles (Chrysemys picta). Eighty-one intact nests were found; 33 were eventually preyed upon during the study. New nests (less than 72 h old) do not appear to have a greater risk of predation than older nests. The majority (55%) of nests preyed upon were older than 72

Age and Experience in Chimpanzee Nest Building
Psychological Reports, 1967Ten captive-born chimpanzee adults (age range 11-30 yr.; M, 21) who had failed to produce nests in repeated individual tests were selected for training. Five were caged adjacent to and five were caged with chimpanzees who regularly constructed nests. All were supplied with pine straw, burlap, newspaper, hose lengths, rope, etc.

Sibling Cooperation Influences the Age of Nest Leaving in an Altricial Bird
The American Naturalist, 2013In altricial birds, siblings raised within a nest usually leave the nest within hours of each other, despite often differing considerably in age. The youngest members of the brood are typically underdeveloped at this time and less likely than their older siblings to survive outside the nest, yet they risk abandonment if they do not fledge with their ...

Identifying the factors that influence nest survival insympatric species is important for the proper and effective management of their breeding populations. We used logistic-exposure models to estimate the daily survival rate and evaluate habitat traits, such as characteristics of trees supporting nests, position of nest in a tree, nesting micro- and ...

Copeia, 1995
In numerous fish species, males provide exclusive parental care of the offspring, and females often use male or nest characteristics to discriminate among potential nests. Little attention, however, has focused on the possibility that once females have chosen a nest, they may also make choices regarding where in the nest to lay their eggs.
