Summary

The brief subarctic summer limits the time available for birds to complete their reproductive activities, yet the temporal requirements of high-latitude passerine migrants are not well understood. Our analyses examined the timing of spring and autumn migration among 18 passerine species to obtain indirect estimates of the time they occupy their breeding ranges in northwestern North America. From 1992 to 1998, the Alaska Bird Observatory (64 degree 50'N, 147 degree 50'W) banded 31,698 individuals during the most intensive standardized mist-netting study ever conducted in subarctic North America.
