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.
Behavioral Studies Of Black-Capped Chickadees At The Uwm Field Station, Millicent S. Ficken
Behavioral Studies Of Black-Capped Chickadees At The Uwm Field Station, Millicent S. Ficken
Field Station Bulletins
This report summarizes studies of the behavior of Black-capped Chickadees (Parus atricapillus) conducted at the UWM Field Station since 1970. Vocalizations and responses to predators are emphasized. Chickadees are very social and their calls are more complex than those of non-social avian species.

Black-Capped Chickadee Behavior-Fledging To Dispersal, Mary Van Male
Field Station Bulletins
Most studies of the family life of young birds after they leave the nest have been descriptive and anecdotal with little quantitative behavioral data, despite the many interesting problems involved in interactions of the members of a family. The objectives of this study were to determine: 1) the behavior of parents and young Black-capped Chickadees (Parus atricapillus) at the time of leaving the nest, 2) how the parents and young behave towards each other during the period when the young are dependent on their parents, 3) the factors responsible for the final disruption of the family. Since aggression was anticipated …
Communication In Ground Squirrels, Robert Ryshke
Communication In Ground Squirrels, Robert Ryshke
Field Station Bulletins
Thirteen-lined ground squirrels (Citellus tridecemlineatus) are among the more abundant and conspicuous Midwestern mammals, yet surprisingly little is known of their behavior under natural conditions, except for the study of McCarley (1966) which concentrated on population dynamics. The object of my study was to describe the general behavior of the ground squirrel, with particular emphasis on postures and vocalizations used in communication. Communication occurs whenever the behavioral activities of one animal affect the activities of another. Communication among members of a group is an essential part of social life, reducing aggression in animal groups as well as synchronizing reproductive activities.
