Parents performed more coordinated switches per hour (6.6 ± 2.8) than unsynchronised feeding trips (2.4 ± 1.3) and the difference was highly significant (t = −5.23, df = 13, p < 0.001).
Parents performed more coordinated switches per hour (6.6 ± 2.8) than unsynchronised feeding trips (2.4 ± 1.3) and the difference was highly significant (t = −5.23, df = 13, p < 0.001).
At the same time there was no significant relationship between parental feeding rate and nest survival time during the poikilothermic nestling stage (r S = −0.34, p = 0.12, n = 14) and a near-significant relationship during the endothermic nestling stage (r S = −0.42, p = 0.052, n = 16).
