Estimating Stage-Specific Daily Survival Probabilities of Nests When Nest age is Unknown [PDF]
The Auk, 2004 AbstractEstimation of daily survival probabilities of nests is common in studies of avian populations. Since the introduction of Mayfield's (1961, 1975) estimator, numerous models have been developed to relax Mayfield's assumptions and account for biologically important sources of variation.

Avian Conservation and Ecology, 2022 Clutch size and number of young fledged has been shown to increase with female age until approximately mid-life, when reproductive performance declines. We used a long-term dataset (2002–019) to investigate age-specific effects on reproductive parameters

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.

Florida harvester ant nest architecture, nest relocation and soil carbon dioxide gradients.
PLoS ONE, 2013 Colonies of the Florida harvester ant, Pogonomyrmex badius, excavate species-typical subterranean nests up the 3 m deep with characteristic vertical distribution of chamber area/shape, spacing between levels and vertical arrangement of the ants by age ...

Nest attendance, incubation constancy, and onset of incubation in dabbling ducks.
PLoS ONE, 2023 In birds, parents must provide their eggs with a safe thermal environment suitable for embryonic development. Species with uniparental incubation must balance time spent incubating eggs with time spent away from the nest to satisfy self-maintenance needs.

International Journal of Gerontology, 2014 Background: As the number of empty-nest elderly rises in the city of Shanghai, ensuring their timely use of health care is a public health concern. The purpose of the study was to examine the home health care needs among the empty-nest elderly living in ...

Effect of Feathers as Nest Insulation on Incubation Behavior and Reproductive Performance of Tree Swallows (\u3cem\u3eTachycineta bicolor\u3c/em\u3e) [PDF]
, 1995 Many species of birds line their nests with feathers, presumably because of the insulative qualities of feathers and because feathers may act as a barrier between nest parasites and nestlings.
