Un nichoir flottant pour grèbe huppé (Podiceps cristatus)
[Conservation]
- A floating nesting raft for Great Crested Grebes
p. 129-139
Abstract
Great Crested Grebes are fastly expanding in Western Europe, especially in Belgium thanks to protection since 1956 and are showing a growing tolerance towards human beings and their activities. Some nests are now exposed in full view and the birds do not require any longer a thick vegetation to hide them. In some places however, some nests that had been hooked at a submerged twig had to suffer quick water level fluctuations owing to repeated flooding from a nearby sluice, which resulted in nests and eggs being lost. A floating nesting raft, which is described, has been successfully tested and appeared to be an attractive nest support able to face water level fluctuations.
