Yesterday, ECAS Wednesday birders talked a bit during our birding as we kept seeing cowbirds. Milt Vine recalled reading info that conflicted with the generally accepted story. See the link, discussion by the esteemed Dennis Paulson. Cheers, Judy, <jmeredit...>
Milt sent: To follow up on the topic of the origination of Brown-headed Cowbird nest parasitism that we were discussing at one of the stops yesterday, check out this 2015 article written by a Washington homeboy, Dennis Paulson. He does not support the "Buffalo Theory" for Brown-headed Cowbird nest parasitism development.
