Evaluating function of stopover sites for Neotropical migrants in the northern Yucatan Peninsula Nearctic-Neotropical migratory songbirds incur the highest mortality rates during their annual migrations. Migratory songbirds use a network of stopover sites to rest, refuel, or seek refuge during times of poor weather conditions; and the time and energy expended at these sites exceeds that of migratory flight. In order to conserve stopover sites with the highest value to Neotropical migrants, a conceptual framework was developed to classify stop over sites into three functional categories based on their function for migratory landbirds, but there have been few attempts to empirically validate this framework. We evaluated the stopover site conservation framework using two protected areas hypothesized to lie at opposite ends of the framework. We use capture data and radio-tracking data to examine patterns in daily capture rates, body condition, rates of mass gain, stopover duration, and departure behavior with a focus on four species; Swainson's Thrush (Catharus ustulatus), Red-eyed Vireo (Vireo olivaceus), Gray Catbird (Dumetella carolinensis), and Prothonotary Warbler (Protonotaria citrea). Our results indicate that variance in daily capture rates, energetic condition, and rates of mass gain are reliable metrics by which to evaluate stopover site function for migratory landbirds. In addition to these metrics, departure direction may provide additional information regarding landscape-scale stopover site use by migratory landbirds. This conservation framework should be used to facilitate stopover site conservation for Neotropical migratory songbirds, and can be applied at sites in the United States as well as tropical regions.
