Abstract

Early life conditions are important for shaping the adult phenotype ofmany organisms. For wild birds, features of the landscape can impactnestling development indirectly via parental effects, and directly viafood quality, predation and disease risk. In this study we investigatedthe relationships between landscape features and parental investmentand nestling condition for five shrubland birds breeding across agradient of developed land and shrubland. Our focal bird specieswere American robin, northern cardinal, field sparrow, brownthrasher, and grey catbird. We found that parental investment and theassociations among morphometric traits varied with changes in landcover, providing evidence for the importance of continuous variationin nest-site habitat features on the development of wild birds.
