About Paper:

Urban areas are expanding and may differ from non-urban areas in the availability of substrates and materials for animals to construct their nests, which many species depend on to mitigate environmental risks. We studied the nest building of Black Phoebe (Sayornis nigricans), a songbird that frequently builds mud-cup nests on human-made structures and breeds in urban areas. In 2023 and 2024, we characterized 103 Phoebe nesting locations along an urbanization gradient in the Sacramento Valley of California, including the surface on which nests are built and the materials used to line nests. We observed Phoebes using a diversity of human-made nesting sites, including some that have not been documented, such as sewer grates, and rice weirs. We expect that Phoebes in urban areas will frequently build their nest on wooden houses, whereas Phoebes in non-urban areas will build on concrete or metal on infrastructure, such as bridges, or on trees. We also expect that birds in urban areas will more frequently use human hair and human-made materials in their nest lining than those in non-urban areas. These results will help us better understand how birds adapt to the novel urban habitat and the challenges they face in these environments.
