: The birds were studied with a license from Landesamt für Gesundheit und Soziales, Berlin (no. 0149/12), and ringed with a license from Vogelwarte Radolfzell (no. 1882). The experimental procedure never caused damage or signs of severe distress to the birds. All birds were released back into the wild, close to their place of capture, immediately after the experiment. The time in captivity for each bird was 40.0 (31.0, 54.0) minutes [<i>median</i> (<i>lower quartile, upper quartile</i>)].
