A new study focused on whether body size influenced the migratory rates of the martins. Researchers collected detailed measurements on each bird before they released it. After they had obtained the migration path information, they compared the birds' individual body measurements to the number and duration of their stopover periods. Their analyses determined that individual variation in stopover length is influenced by the size of the bird, and the size of its wings.
