Table 2 Comparing models hypothesized to explain variation in stopover duration (h) and daily activity (proportion of a day (500–1900 h) spent active) for Red-eyed Vireos at two sites over two years during fall migration on the coast of the Yucatan Peninsula

  1. The evidence for or against a model was assessed using Akaike’s Information Criterion corrected for small sample size (AICc)
  2. We did not analyze daily activity for birds at the Isla Contoy site because of low sample size
