Recent declines in migratory bird numbers have led researchers to evaluate where conservation efforts would have the greatest impact on population recovery. Ornithologists are especially interested in identifying and protecting important stopover sites found along spring and fall migration routes. Birds use these habitats to rest and refuel before continuing to migrate, and quality of food and shelter there may determine if birds are able to reach their destination. Lake Ontario serves as a barrier to migrating birds, so it is especially important for them to rest and rebuild fat stores before attempting to cross the lake. This study compares fat storage and usage in white-throated sparrows (Zonotrichia albicollis) stopping along the Lake Ontario shoreline against birds stopping farther inland. By also considering factors such as age, sex, and body condition, we hope to learn more about how birds choose stopover sites and how they spend time there.
