The dominance hierarchy of the Black-capped Chickadee and it's relation to breeding territory and frequency of visitation to an artificial food source
نویسنده
چکیده
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.

—Analysis of the structure and stability of a hybrid zone can serve as a starting point for examining mechanisms that infl uence spatial and evolutionary relationships between species. Recent studies of the hybrid zone between Blackcapped Chickadee (Poecile atricapillus) and Carolina Chickadee (P. carolinensis) have suggested that genetic introgression is limited to a narrow zone, while also re...

Artificial neural networks were trained to discriminate between two different notes from the "chick-a-dee" call of the black-capped chickadee (Poecile atricapillus). An individual note was represented as a vector of nine summary features taken from note spectrograms. A network was trained to respond to exemplar notes of one type (e.g., A notes) and to fail to respond to exemplar notes of anothe...

The tseet contact call, common to black-capped (Poecile atricapillus) and mountain chickadees (P. gambeli), is the most frequently produced vocalization of each species. Previous work has characterized the tseet call of black-capped and mountain chickadees from different geographic locations in terms of nine acoustic features. In the current study, using similar methods, the tseet call of black...
