preference for redder gapes in open- nesting passerines, or that the bright red gape of nestling cuckoos has evolved to exploit parental preferences in these three hosts. We suggest that although mouth colour has little in uence on the allocation of feeds resulting from sibling competition and begging

, 1983). Strong size hierarchies may be adaptive in that they reduce sibling competition (Hahn, 1981) and peak food demands of young (Bryant, 1978). However, the usual consequence of size disparity is a skewed resource allocation within brood, leading to reduced growth rate, lower body masses and even
