Habitat‐dependent occupancy and movement in a migrant songbird highlights the importance of mangroves and forested lagoons in Panama and Colombia

摘要: Climate change is predicted to impact tropical mangrove forests due decreased rainfall, sea-level rise, and increased seasonality of flooding. Such changes are likely influence habitat quality for migratory songbirds occupying wetlands during the dry season. Overwintering known be associated with fitness in songbirds, yet studies have focused primarily on territorial species. Little about ecology nonterritorial species that may display more complex movement patterns within among habitats differing quality. In this study, we assess within-season survival at two spatio-temporal scales a overwintering bird, prothonotary warbler (Protonotaria citrea), depends mangroves lowland forests. Specifically, (a) estimated within-patch persistence over six-week period using radio-tagged birds central Panama (b) modeled abundance occupancy dynamics survey points throughout eastern northern Colombia as season progressed. We found site was highest mangroves; however, probability did not differ habitats. The canopy cover, wet were least experience local extinction also tallest canopies. This study one first demonstrate habitat-dependent migrant songbird, our findings highlight need conserve intact, mature mangrove,
