As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Penguin cam captures hunt for prey

Little penguins work together to hunt schooling prey

Little penguins were more likely to work together to hunt schooling prey than solitary prey, according to observations made using animal-borne cameras published Dec. 2, 2015 in the open-access journal PLOS ONE by Grace Sutton from the Deakin University, Australia, and colleagues.
Group foraging in cooperative animals provides predators with advantages over prey, but for less cooperative colonial-breeding predators, like the little penguin, the benefits of group foraging are less clear due to the potential for competition between penguins. The authors of this study used animal-borne cameras on 21 little penguins from two breeding colonies in south-eastern Australia to determine the prey types, hunting strategies, and success of little penguins, a small, marine predator that extensively forages with other little penguins.
