An Experimental Study of Chick Provisioning in the Cooperatively Breeding Acorn Woodpecker
Acorn woodpeckers (Melanerpes formicivorus) are cooperative breeders in which groups consist of a variable number of cobreeding males, jointnesting females, and non-breeding helpers of both sexes that are offspring from prior nests. We temporarily manipulated brood size of nests to determine the feeding response of birds in relation to their status (breeder or non-breeding helper) and sex. All ...
متن کاملBrooding, provisioning, and compensatory care in the cooperatively breeding acorn woodpecker
We analyzed reproductive investment in parental care (brooding and the provisioning of nestlings) in the acorn woodpecker (Melanerpes formicivorus), a cooperatively breeding species in which both polygynandry and helping-at-the-nest are common. As predicted based on the strategies pursued by birds of different sex and status, breeders generally invested more in parental care than helpers, and b...

http://dx.doi.org/10.1016/j.anbehav.2016.06.002 0003-3472/© 2016 The Association for the Study of A Acorn woodpeckers, Melanerpes formicivorus, are cooperative breeders in which social groups consist of both nonbreeding helpers at the nest (offspring from prior reproductive attempts) and cobreeders of one or both sexes (usually siblings or a parent and his/her offspring). Regardless of composit...

متن کاملDistress Calls in the Acorn Woodpecker
Acorn Woodpeckers live in extremely stable kin groups. Nonetheless, only 59.9% of birds caught in roosting aggregations gave distress calls or fear screams. Distress calling was highly repeatable among individuals and apparently heritable. However, the incidence of distress calling did not vary seasonally or according to age, sex, or status. Also, with two marginally significant exceptions, dis...
