Interaction Between Early Experience and Depth Avoidance in Young Eider Ducks (Somateria Mollissima L.)
Abstract Speed estimations of eider broods descending into the sea for the first time revealed no hesitation between ground and depth at the shoreline. In a laboratory experiment, however, dark-reared young (N = 10) exhibited strong resistance when pushed from the shallow towards the deep side of a...

Abstract Speed estimations of eider broods descending into the sea for the first time revealed no hesitation between ground and depth at the shoreline.

The same young hesitated in crossing from shallow to deep when lured by playbacks of the female's grock-call. In contrast, differential reactions to depth were absent during free swimming in a water-filled visual cliff. In another experiment, young exposed to a deep texture (N = 21) for 2 to 24 hours revealed significantly more deep choices than a matched group of shallow-exposed (N = 20) and a group of unexposed young (N = 7).
