In recent years, temperatures have increased globally, and by different amounts locally. As local climates change increase, nestlings from a variety of bird species are exposed to the threat oxidative stress, producing adverse effects on growth survival offspring. One defence against stress is increase dietary intake antioxidants. I tested hypothesis that experimental heating house wren nests during incubation period leads in predicted would lead decreased young, but these negative be ameliorated supplements anti-oxidant vitamin E, found naturally invertebrate prey with which parents provision their young. employed split-brood design experimentally manipulated nest temperature entire broods, while simultaneously providing E half within broods. To control for possibility might also influence maternal behavior, thereby potentially confounding any treatment effects, recorded female effort.

These results suggest specific limits, climate development cavity-nesting birds can mitigated adjustments behaviour.

Stressors associated with urban habitats have been linked to poor wildlife health but whether a general negative relationship between urbanization and animal can be affirmed is unclear. We conducted meta-analysis of avian literature test biomarkers differed on average non-urban environments, there are systematic differences across species, biomarkers, life stages species traits. Our dataset included 644 effect sizes derived from 112 articles published 1989 2022, 51 bird species. First, we showed that was no clear impact when categorized the sampling locations as or non-urban. However, did find small this dichotomous variable replaced by quantitative representing degree at each location. Second, dependent type biomarker measured well individual stage, young individuals being more negatively affected. comprehensive analysis calls for future studies disentangle specific urban-related drivers might obscured in categorical versus comparisons.
