Itasca Biological Station Bear Paw Point Breeding Bird Census, 1979-2024

This dataset is part of an ongoing effort that began in 1979 at the University of Minnesota Itasca Biological Station to conduct an annual census of breeding bird territories on Bear Paw Point every spring. Students enrolled in Field Ornithology used an established 50x50 meter grid (11.5 hectares total plot size) and walked gridlines, identifying bird songs and estimating the number of singing males heard to determine the number of breeding territories for different species present on Bear Paw Point.
