Recognition Of Brood-Mate Vocalizations By Northern Bobwhite (Colinus Virginianus) Chicks, Susan St. Clair Raye
Recognition Of Brood-Mate Vocalizations By Northern Bobwhite (Colinus Virginianus) Chicks, Susan St. Clair Raye
Field Station Bulletins
Unrelated bobwhite quail (Colinus virginianus) chicks were hatched together and raised together. Each chick was tested in an arena with tape recorded separation, contentment and distress calls from a brood-mate and an unfamiliar chick of the same age. Chicks at one, six and 19 days of age gave significantly more separation calls in response to the separation calls of their brood-mates than they gave in response to the separation calls of the strange chicks. Since the chicks were not related, this ability to recognize brood-mate vocalizations is probably learned. Sibling recognition in quail might function in inbreeding avoidance.
The Dominance Hierarchy Of The Black-Capped Chickadee And It's Relation To Breeding Territory And Frequency Of Visitation To An Artificial Food Source, Craig Thompson
Field Station Bulletins
A peck-dominant type of dominance hierarchy was demonstrated in a group of twenty-one Black-capped Chickadees and was consistent with what is expected of this species of Paridae at the interflock level. No significant correlations were found between dominance and frequency of visitation to the study feeder, between dominance and distance from feeder to 1980 breeding territory, and between distance to territory and frequency of visitation.
