Communally breeding female Barn Owls Tyto alba are not related and do not invest similarly in the communal family
Bird Study, 2019•Taylor & Francis
We report detailed information about relatedness and parental investment in a communal
nest in the Barn Owl Tyto alba. Two unrelated females laid their eggs in a single nest cup
and successfully raised 4 nestlings out of 11 laid eggs. Apparently, the yearling female did
not incubate the eggs and only occasionally hunted for the brood, in contrast to the older
female which invested more effort in parental care.
