Tide and habitat features affect salt marsh songbird nest survival in northeast Florida, USA
Endangered Species Research, 2020 Tidal salt marshes face numerous pressures that threaten their ecological integrity, and many salt marsh vertebrates have exhibited declines concomitant with the degradation of salt marsh habitats.

Egg crypsis in a ground‐nesting shorebird influences nest survival [PDF]
Ecosphere, 2013 Coloration of exposed eggs of ground‐nesting birds is thought to reduce predation, with camouflaged eggs that more closely match the area around the nest having greater survival. We tested this hypothesis using digital photographs of 374 Mountain Plover (Charadrius montanus) nests and the substrate surrounding each nest to produce covariates in nest ...

A Distribution-Free Nest Survival Model
Biometrics, 1988 In many nest survival studies, nests are not found until after incubation has begun and nests that fail are of unknown age while nests that succeed can be aged afterwards. Typically ornithologists have considered the survival time to be from first encounter and have used the Mayfield method (Mayfield, 1961, Wilson Bulletin 73, 255-261; Mayfield, 1975 ...

Vegetation phenology and nest survival: Diagnosing heterogeneous effects through time. [PDF]
Ecol Evol, 2019 Birds should select nest sites that minimize predation risk, but understanding the influence of vegetation on nest survival has proven problematic. Specifically, the common practice of measuring vegetation on nest fate date can overestimate its effect on

Physical cognition : birds learn the structural efficacy of nest material [PDF]
, 2014 This work was supported by the BBSRC (BB/I019502/1) and Roslin Institute Strategic Grant funding from the BBSRC. The APC was paid through RCUK OA block grant funds.It is generally assumed that birds’ choice of structurally suitable materials for nest ...

Canada goose nest survival at rural wetlands in north‐central Iowa
Wildlife Society Bulletin, 2016 The last comprehensive nest survival study of the breeding giant Canada goose (Branta canadensis maxima) population in Iowa, USA, was conducted >30 years ago during a period of population recovery, during which available nesting habitat consisted ...

Nest-site selection and breeding success of passerines in the world’s southernmost forests [PDF]
PeerJ, 2020 Background Birds can maximize their reproductive success through careful selection of nest-sites. The ‘total-foliage’ hypothesis predicts that nests concealed in vegetation should have higher survival.

Behavioral strategies during incubation influence nest and female survival of Wild Turkeys
Ecology and Evolution, 2020 Females must balance physiological and behavioral demands of producing offspring with associated expenditures, such as resource acquisition and predator avoidance. Nest success is an important parameter underlying avian population dynamics.

PLoS ONE, 2021 Grassland birds are declining faster than any other avian guild in North America and are increasingly a focus of conservation concern. Adaptive, outcome-based management of rangelands could do much to mitigate declines.
