a) Weather stations within 100 km from the Ithaca, NY site (42.5037 N, −76.4661) used during the reproduction life history stage. b) Weather data sampled within 177 km of the overwintering habitat of Ithaca Tree Swallows (26.6503 N, −81.5003 W). c) Weather station sites sampled within 177 km of the midpoint during spring migration (36.2908 N, −78.4121 W) as they return to breed in Ithaca, NY. All points are determined via direct observation of from geolocators from Tree Swallows recaptured in Ithaca, NY.
