Waterbird Nest Density and Nest Survival in Rice Fields of Southwestern Louisiana

Waterbirds, 2010
Abstract. Rice fields in southwestern Louisiana provide breeding habitat for several waterbird species; however, little is known about nest density, nest survival and the importance of landscape context of rice fields in determining breeding activity. In 2004, 42 rice fields were searched for nests, and 40 were searched in 2005.

NEST-SITE SELECTION AND NEST SURVIVAL OF NORTHERN BOBWHITE IN SOUTHERN TEXAS

The Wilson Journal of Ornithology, 2007
Abstract We examined abiotic and biotic variables potentially associated with Northern Bobwhite (Colinus virginianus) nest-site selection and nest success in southern Texas, USA during 2002–2005. These data were used to characterize bobwhite nest-site selection, and to develop and evaluate models of daily nest survival in Program MARK.

Possible Effects of Nest Predation on Ground Nest Survival in the Neretva Delta (Croatia)

Avian Biology Research, 2010
Nest predation experiment to survey survival probabilities of larger bodied ground-nesting birds (ducks) was carried out on Lake Kuti in May 2006. From 25 artificial ground nests on the floating reedbed islands and 25 nests on the grazed islands, 8 and 1, respectively, were depredated.

Handling of uncertain nest fates and variation in nest survival estimates

Journal of Ornithology, 2007
Researchers are moving their attention away from the Mayfield method of estimating nest success to advanced nest survival models that can be implemented within statistical software packages. In spite of this, little attention has been paid to developing formal rules for handling of ambiguous nesting data within these software-based methods.

Intraseasonal patterns in shorebird nest survival are related to nest age and defence behaviour

Oecologia, 2010
Nest 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.

Nested case‐control study designs for left‐truncated survival data

Canadian Journal of Statistics, 2017
AbstractThe determination of risk factors for disease incidence has been the subject of much epidemiologic research. With this goal a common study design entails the follow‐up of an initially disease‐free cohort, keeping track of the dates of disease incidence (onset) and ascertaining covariate (putative risk factor) information on the full cohort ...

Personality and density affect nest defence and nest survival in the great tit

acta ethologica, 2014
Recent studies suggest that individual variation in behaviour of prey individuals may cause distinctive responses to nest predators and cooperation with conspecifics. We assessed individual differences during a novel object test and whether these responses were related to nest failure and survival of females during incubation.

Effect of nest site on nest survival in the Dunnock Prunella modularis

1991
Nest survival and breeding success were studied in relation to nest site at 134 Dunnock nests in southern Finland. The nests were grouped according to three site categories : 1) small spruce, 2) shrub, and 3) heap of spruce twigs and branches (brush pile).
