Relationship of Weather to Migratory Movements of Black-Tailed Deer

Abstract

A study of the influence of weather factors on the migrations of a herd of blacktailed deer showed that periods of migration as indicated by night spotlight samples were closely correlated with seasonal changes in minimal relative humidity. Both spring and fall migrations, and possibly an atypical summer movement, occurred during ranges of 40 to 60% minimal relative humidity. Snowstorms, rainfall, absolute humidity, and temperature were not so closely correlated. The migrations could not be attributed to habitat factors such as food, water, or escape cover.
