Relationships Between Habitat and Snag Characteristics and the Reproductive Success of the Brown-headed Nuthatch (Sitta pusilla) in Eastern Texas. [PDF]

open access: yes, 2004
Habitat use and reproductive success of the Brown-headed Nuthatch (Sitta pusilla Latham) were studied in East Texas during the 2001-2002 breeding seasons. We compared nest cavity selection at used and randomly selected non-used areas.

Smelling out predators is innate in birds [PDF]

open access: yes, 2011
The role of olfaction for predation risk assessment remains barely explored in birds, although predator chemical cues could be useful in predator detection under low visibility conditions for many bird species.

Experimentally induced antipredator responses are mediated by social and environmental factors [PDF]

open access: yes, 2019
Nest predation is a common cause of reproductive failure for many bird species, and various antipredator defense behaviors have evolved to reduce the risk of nest predation.

Scenarios of habitat management options to reduce predator impacts on nesting waders [PDF]

open access: yes, 2017
1. Wetland ecosystems throughout the world are threatened by drainage and intensification of agriculture. Consequently, many wetland species of conservation concern are now restricted to fewer and smaller sites, and maintaining these species often ...

Nest predation in the African blue tit Cyanistes teneriffae Lesson, 1831 (Aves, Paridae) . Using nest-boxes and artificial nests.

open access: yesZoodiversity, 2020
Predation on breeding blue tit populations in north-eastern Algeria has been studied in nest boxes during a five years fieldwork (2003-2007) in cork oak forests. Nest boxes were placed each year in Brabtia plain forest in El Kala National Park.

The influence of landscape features on nest predation rates of grassland-breeding waders [PDF]

open access: yes, 2015
In Europe, lowland wet grasslands have become increasingly fragmented, and populations of waders in these fragments are subject to unsustainably high levels of nest predation.

Assessing the Consequences of Brood Parasitism and Nest Predation On Seasonal Fecundity in Passerine Birds [PDF]

open access: yes, 1995
Brood parasites and nest predators reduce the seasonal fecundity and, hence, the population growth rates of their victims. However, most field studies do not measure directly how parasites and predators decrease seasonal fecundity, but instead measure ...

Rat snakes, cowbirds, and vines lower passerine nest survival in remnant bottomland hardwood forests in east-central Arkansas, USA

open access: yesAvian Conservation and Ecology, 2021
Predation is often the leading cause of nest failure among passerines; however, specific causes are often unknown or can be misidentified in the field.

Spatiotemporal Effects of Supplementary Feeding of Wild Boar (Sus scrofa) on Artificial Ground Nest Depredation. [PDF]

open access: yesPLoS ONE, 2015
Supplementary feeding of ungulates, being widely used in game management, may have unwanted consequences. Its role in agricultural damage is well-studied, but few studies have considered the potential for the practice to attract ground nest predators ...

Carcasses attract invasive species and increase artificial nest predation in a desert environment

open access: yesGlobal Ecology and Conservation, 2021
In addition to feeding on animal remains, many scavengers also function as predators. Carcasses may therefore affect local animal communities by attracting facultative scavengers and increasing predation risk for other species in the vicinity of the ...
