Wilson’s Warbler is a leapfrog migrant passerine that winters in Central America and breeds throughout North America. Birds were captured in the spring and fall of 2006 during passage through a desert stopover site in southern Arizona. Total migration distance of individuals was assessed using deuterium ratios of tail feathers, stopover duration was estimated using mark-recapture analysis of color-banded birds, and relative refueling rate was measured using plasma metabolite analysis. Compared to short-distance migrant individuals, longer-distance migrants passed through later during spring migration, had shorter minimum lengths of stay, larger fuel stores and a higher rate of refueling. During autumn, longer-distance migrants passed through later, but there was little variation in minimum length of stay.
