dc.description.abstract	‘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.	sr
