Fight or flight: Geographic variation in antipredator defenses by cinereous tits
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 ...

Nest remains are insufficient to identify predators of waterfowl nests
Context Nest predation is a leading cause of nest failure for most ground-nesting birds. Methods that allow for accurate classification of fate and identification of predators are important for understanding productivity and conservation strategies.

EFFECT OF RACCOON (PROCYON LOTOR) REDUCTION ON BLANDING’S TURTLE (EMYDOIDEA BLANDINGII) NEST SUCCESS [PDF]
The Lake County Forest Preserve District has monitored a state-endangered Blanding’s Turtle (Emydoidea blandingii) population at two adjoining nature preserves along the Illinois–Wisconsin border since 2004.

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 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]
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

Nest attentiveness drives nest predation in arctic sandpipers
Most birds incubate their eggs to allow embryo development. This behaviour limits the ability of adults to perform other activities. Hence, incubating adults trade off incubation and nest protection with foraging to meet their own needs. Parents can either cooperate to sustain this tradeoff or incubate alone.

Nest predation on birds that nest in rock cavities in a tropical limestone forest of southern China
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 ...

Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...
