| dc.description.abstract |
Populations of redwinged blackbirds (Agelaius phoeniceus phoeniceus) vary in density in different habitats in the Ottawa area. Population densities in three sample areas are defined in terms of numbers of breeding birds and numbers of nests. An attempt is made to define environmental factors which influence population densities in the different sample areas and affect census methods. Feeding of wild and captive birds were studied. |
