Four young Savannah sparrows rest in their nest, which is monitored as part of a long-term population study on Kent Island, New Brunswick. We investigate the population dynamics, migratory behavior, and ecology of this population. Monitoring nests provides information on reproductive effort, success, and timing. These sparrow nestlings are about 5 days old and will soon be marked with colored leg bands for identification in the field before they leave the nest at around 10 days old.
