Dispersal Movements Of Juvenile Black-Capped Chickadees, John R. Meyer, Charles M. Weise
Dispersal Movements Of Juvenile Black-Capped Chickadees, John R. Meyer, Charles M. Weise
Field Station Bulletins
To learn more about Chickadee dispersal this study was undertaken from the summer of 1970 through the summer of 1973, involving the color-banded population of Black-capped Chickadees at the UW-M Cedar-Sauk Field Station described by Weise (1971). The most intensively studied birds were located in about 26 hectares of upland beech-maple forest and about 30 hectares of the cedar-tamarack bog forest at and immediately surrounding the Field Station. The territories of the breeding pairs in these areas were mapped, and as many nests as possible were located. The development of the young in accessible nests was followed, and just before …
Black-Capped Chickadee Behavior-Fledging To Dispersal, Mary Van Male
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 …
Population Dynamics Of The Black-Capped Chickadee, Charles M. Weise
Population Dynamics Of The Black-Capped Chickadee, Charles M. Weise
Field Station Bulletins
The Black-capped Chickadee is an abundant, familiar bird in Wisconsin, known to almost everyone. In summer it is widespread in nearly all kinds of woods, although it is more numerous in younger second-growth forests, swamp forests or along forest-edges than in mature climax types. In winter, it becomes more restricted to dense thickets, bogs or swamps, especially where conifers like cedars or hemlocks occur; however, it also congregates in large numbers in towns or suburban areas wherever it can find artificially provided food at bird-feeding table. ecology. Since 1968 we have been concentrating our efforts more and more on a …
Winter Bird Studies At The Uwm Field Station, Charles M. Weise
Winter Bird Studies At The Uwm Field Station, Charles M. Weise
Field Station Bulletins
The winter trapping program was begun in the winter of 1965-66 and was expanded and conducted more systematically in 1966-67 and 1967-68. The primary objective has been to determine accurately the daily and seasonal changes in body weight and depot fat in the Chickadee and Junco. Secondarily, we (my students and I) have been interested in the winter population densities of these birds, their organization into social groups and flocks, their movements and range of activity in the local area.
