Detroit River-Western Lake Erie Basin Indicator Project

INDICATOR: Detroit River Christmas Bird Count

Map of the annual Detroit River Christmas Bird Count

The Detroit River annual Christmas Bird Count (CBC) was established in 1978 as a binational endeavor to count overwintering birds. The area covered is a circle centered on Detroit, encompassing parts of both Wayne County in Michigan and Essex County in Windsor. The count circle consists of mostly industrial, urban, and residential areas, but includes some natural areas, such as the Ojibway Prairie in Windsor and wetlands along the Detroit River that are critical for bird populations.
