Nestling development in the alpine : predation risk, parental care, and environmental conditions across the annual cycle ...
Offspring development is a critical life-history stage for altricial songbirds and a prime target for selection, as predation risk is high relative to other life-stages and environmental conditions can induce lasting consequences for life-time fitness. Nestling development rates vary widely among sp...

Offspring development is a critical life-history stage for altricial songbirds and a prime target for selection, as predation risk is high relative to other life-stages and environmental conditions can induce lasting consequences for life-time fitness.

Rapid development is considered an evolved response to improve nest success given high predation risk at the species or population level. However, it is unclear what drives variation in development rate among individuals and whether offspring or parents have the adaptive capacity to respond to prevailing stressors.
