Duration of ‘peeks’ in ducks: how much time do Pochard Aythya ferina spend with eye open while in sleeping posture?
Апстракт
‘Peeks’, or keeping an eye open, in wintering Pochard Aythya ferina, while in sleeping posture, were relatively brief, typically (66% of observations) lasting less than 1s; however, in 37% of individuals some peeks lasted 10 s or more. Contrary to our prediction of lower anti-predatory vigilance rates in larger groups, there was a positive relationship between peek duration and the numbers of neighbours in a flock.
