Parental energy expenditure in relation to manipulated brood size in the European kestrel Falco tinnunculus
Zoology-Analysis of Complex Systems, 1995•research.rug.nl
Parental daily energy expenditure (DEE (par)) of European kestrels Falco tinnunculus with
manipulated brood sizes was measured with the doubly labelled water (DLW) method. The
reproductive output of the experimental broods increased with brood size. DEE (par) was
positively associated with the number of young that were added to the brood, while no
association with original brood size could be established.

Abstract
Parental daily energy expenditure (DEE (par)) of European kestrels Falco tinnunculus with manipulated brood sizes was measured with the doubly labelled water (DLW) method. The reproductive output of the experimental broods increased with brood size. DEE (par) was positively associated with the number of young that were added to the brood, while no association with original brood size could be established.
