NettetUnderwater video graphy was used to examine the patterns of behaviour and relative success rates of U-shaped and V-shaped dives in Australasian gannets and found that gannet adjusted their dive shape in relation to the depth of their prey rather than prey type, as previously hypothesized. Gannets are specialist plunge divers that perform short … NettetWe find that the neck length, neck muscles, and diving speed of the bird predominantly reduce the likelihood of injury during the plunge-dive. Finally, we use our results to …
