Growth and Behaviour of Young Ospreys Pandion haliaetus
Oikos, 1977The growth rate (K) of young ospreys Pandion haliaetus L. as described by a logistic equation is 0.12; the average length of time required to grow from 10 to 90 % of the asymptotic weight is 36.7 d. There is an inverse relationship between brood size and the fledging weight of the chicks.
