Table 2 Effects of weather variables and day of year on night-to-night departure probability in Northern Wheatears, European Robins and Common Blackbirds

From: Stopover departure decisions in songbirds: do long-distance migrants depart earlier and more independently of weather conditions than medium-distance migrants?
