Migratory double breeding in Neotropical migrant birds.
Neotropical migratory songbirds typically breed in temperate regions and then travel long distances to spend the majority of the annual cycle in tropical wintering areas. Using stable-isotope methodology, we provide quantitative evidence of dual breeding ranges for 5 species of Neotropical migrants. Each is well known to have a Neotropical winter range and a breeding range in the United States ...
متن کاملUnderstanding the Stopover of Migratory Birds: A Scale Dependent Approach
The development of comprehensive conservation strategies and management plans for migratory birds depends on understanding migrant-habitat relations throughout the annual cycle, including the time when migrants stopover en route. Yet, the complexity of migration makes the assessment of habitat requirements and development of a comprehensive conservation strategy a difficult task. We emphasize t...
متن کاملModeling Stopover Sites of Migratory Birds’ Routes for Conservation of Population and Prevention of Disease
Modeling migratory paths of birds is an emerging area of complexity science in which attracts interdisciplinary collaborations from ornithologists, computer scientists, epidemiologist, and policy makers. However, due to the unpredictability of climate and habitat changes, our understanding of bird migratory paths is still limited. Not accounting for environmental changes when modeling bird migr...
متن کاملSerological Monitoring of Avian Influenza in Migratory Birds of Iran
Although migratory waterfowl is well known to be a major reservoir for avian influenza virus (AIV), there are only few recently published reports about the seroprevalence of AIV in this group of birds. To investigate the AIV antibody status in migratory waterfowl of Iran, we collected 217 serum samples from 25 different species of waterfowl during 2003 and 2004. These serum samples were teste...
متن کاملStopover ecology of a migratory ungulate.
1. Birds that migrate long distances use stopover sites to optimize fuel loads and complete migration as quickly as possible. Stopover use has been predicted to facilitate a time-minimization strategy in land migrants as well, but empirical tests have been lacking, and alternative migration strategies have not been considered. 2. We used fine-scale movement data to evaluate the ecological role ...
