We studied the relationship between two macro-scale environmental factors (i.e., rainfall, temperature) and the arrival of Barn Swallows (Hirundo rustica) to a Mexican Neotropical city in the past 13 years (1997?2009). Temperature was not related to arrivals, but February rainfall in Mexican wintering lands (one month prior to arrival date) showed a significant positive relationship with the migratory phe- nology of Barn Swallows. We believe that the relationship between February rainfall in Mexican wintering lands and the arrival of Barn Swallows to Morelia is related to the reduction of flying speed and/or pro- gression under unfavorable environmental conditions. Thus, in a global change scenario, the arrival date of Barn Swallows could change in the future in response to altered precipitation patterns. Accepted 6 January 2010.
