Acorn Woodpeckers, best known for their unique habit of storing acorns by the thousands in special structures known as “granaries”, are cooperative breeders that exhibit one of the most complex social systems of any bird. Based
on a long-term study of this species at Hastings Natural History Reservation in Monterey County,
Walt will explain some of the strikingly cooperative and diabolically competitive behaviors of this species that he and his
colleagues have discovered during their 50+ year field study.
