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.
The Influence Of Winter Social Behavior On The Habitat Selection And Reproductive Success Of The Black-Billed Magpie, Kerry P. Reese
The Influence Of Winter Social Behavior On The Habitat Selection And Reproductive Success Of The Black-Billed Magpie, Kerry P. Reese
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study examined the influence of winter social behavior, particularly dominance relationships, on the subsequent nesting habitat selection and reproductive success of Black-billed Magpies (Pica pica hudsonia) on 2 areas in northern Utah. Hierarchical cluster analysis ordinated the habitats available to breeding birds and Chi-square and Bonferoni-z statistics were used to determine those habitat types the magpies seemed to prefer. Social status was determined by observing color-banded birds engaged in agonistic encounters at winter bait stations. Social dominance was evaluated by % dyads won, not by total % victories. Relationships between winter social status of magpies and their …

Deep Woodchip Litter: Hygiene, Feeding, And Behavioral Enhancement In Eight Primate Species, Arnold S. Chamove, James R. Anderson, Susan C. Morgan-Jones, Susan P. Jones
Ethology Collection
Sixty-seven animals from eight primate species were used to assess improved husbandry techniques. The presence of woodchips as a direct-contact litter decreased inactivity and fighting, and increased time spent on the ground. Placing food in the deep litter led to further behavioral improvement. The use of frozen foods improved food distribution and reduced fighting in most situations, especially when it was buried in the litter. With time, the litter became increasingly inhibitory to bacteria. The results suggest that inexpensive ways of increasing environmental complexity are effective in improving housing for primates.
