RE: Avian Cannibals



I've seen Barn Owl chicks prey on their younger and weaker siblings. Not
nice - they simply pick up their unfortunate nest mate and consume it alive,
head first.

A quick check for some variations on "avian cannibalism" on Google turned
up these papers. Nest cannibalism and cannibalism among confined poultry
seem to be rather common. Bad weather and other food stress may also be a
cause.
