Avian Research, 2018 Background Nest predation is usually the main cause of bird nest failure. ‘Predation avoidance hypothesis’ of nest-site selection predicts that birds should prefer nest-sites with higher nesting success.

Incubating parents serve as visual cues to predators in Kentish plover (Charadrius alexandrinus).
PLoS ONE, 2020 Ground-nesting birds face many challenges to reproduce successfully, with nest predation being the main cause of reproductive failure. Visual predators such as corvids and egg-eating raptors, are among the most common causes of nest failure; thus ...

Fight or flight: Geographic variation in antipredator defenses by cinereous tits
Global Ecology and Conservation, 2020 In the face of death from predation, parent birds have to choose between prioritizing current versus future reproduction. Previous studies have shown that when exposed to predation risk, birds breeding in the tropics prioritize their own safety, whereas ...

Global Ecology and Conservation, 2020 Nest predation is a major limiting factor of bird reproductive success, and predation by snakes may have particularly adverse effects on passerines. The reed parrotbill (Paradoxornis heudei) is a threatened passerine that inhabits reedbeds in East China,

Deceptive nest defence in ground-nesting birds and the risk of intermediate strategies. [PDF]
PLoS ONE, 2018 Nest predation is an important determinant of reproductive success and ground-nesting birds exhibit a variety of nest defence strategies to mitigate the risk. Many small-bodied, ground nesting birds rely on deceptive behaviours such as injury-feigning to

Journal of Field Ornithology, 2023 Temperate zone songbirds in North America can experience high levels of nest predation and Brown-headed Cowbird (Molothrus ater) parasitism, which may contribute to population declines, and an important question is whether nesting females can mitigate ...

Nest predation on birds that nest in rock cavities in a tropical limestone forest of southern China
Global Ecology and Conservation, 2017 High nest predation is often found in tropical birds, though data from tropical limestone regions are lacking. In a limestone karst rainforest of south China, two species of babblers breed in rock cavities in different seasonal periods: the endangered ...

Ecosphere, 2022 Turtles are killed on roads, yet there is little evidence of negative road effects on their abundances. We hypothesized that this could be due to reduced predation of turtle nests laid along roadsides, which could compensate for the effects of higher ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.
