Each year Bighorn Audubon Society participates in the International Migratory Bird Day Spring Bird Count. When combined with other surveys, such as the Breeding Bird Survey, this survey provides a picture of how the continent’s bird populations have changed in time and space over the past hundred years. Data are combined within a large pool in order to evaluate continental changes in bird populations. Locally, the one-day count data are sent to the non-game division of Wyoming Game and Fish in Lander to aid in the understanding of local bird populations and their changes.
