Natural nest cavities in a high elevation habitat provide a more constant thermal environment than human-made nest cavities

Nest orientation and proximity to snow patches are important for nest site selection of a cavity breeder at high elevation

Carole A. Niffenegger et al.

Summary: Timing and location of reproduction are important for the reproductive success of birds, especially in mountain ecosystems with high spatiotemporal variability and climate shifts. The white-winged snowfinch prefers nest cavities facing the morning sun and located in areas with greater snow cover. The future climate change may lead to mismatches between foraging grounds and nest sites, impacting the demographic trajectories of the snowfinch.

Microclimate shifts in nest-boxes and natural cavities throughout reproduction

Joanna Sudyka et al.

Summary: Animals breeding in nest-boxes experience poorer thermal properties compared to natural cavities, leading to compromised thermoregulation of offspring. Conservation efforts should prioritize protecting natural breeding-hollows to mitigate the potential impacts of climate change on breeding animals.

Nest-boxes alter the reproductive ecology of urban cavity-nesters in a species-dependent way

Joanna Sudyka et al.

Summary: Human-provided nesting shelters can mitigate the shortage of natural breeding sites, but their impact on the fitness of birds is unclear. By comparing two small passerine species breeding in nest-boxes and natural cavities in an urban forest, we found that different species have different responses to nest-boxes.

Limited heat tolerance in an Arctic passerine: Thermoregulatory implications for cold-specialized birds in a rapidly warming world

Ryan S. O'Connor et al.

Summary: The study found that snow buntings have a limited heat tolerance, experiencing heat stress when air temperatures are below their body temperature. This suggests that their well-developed cold tolerance may come at the cost of reduced heat tolerance, potentially impacting their ability to cope with warming Arctic temperatures.
