As part of the 121st annual Audubon Christmas Bird Count, Lardeau’s 24th CBC took place on December 27th. Thirty enthusiastic but physically distanced participants recorded 38 species on count day (on par with the average of 36) and an additional 6 species during the count week. Some highlights are that there were no Barrow’s goldeneyes nor Evening Grosbeaks reported at all during the entire count week. For only the second time in 24 years and 2nd year in a row, a Marsh wren was recorded at an Argenta slough.

The Audubon CBC is one of the longest-running wildlife censuses in the world. Each individual count takes place in a 15-mile-wide circle. Within each circle, participants tally all birds seen or heard that day—not just the species but total numbers to provide a clear idea of the health of that particular population. When combined with other surveys such as the Breeding Bird Survey, the Audubon CBC provides a picture of how the continent’s bird populations have changed in time and space over the past twelve decades. The long-term perspective is vital for conservationists. It informs strategies to protect birds and their habitat, and helps identify environmental issues with implications for people as well.
Audubon CBC data are also used to measure how birds are already responding to climate change. By tracking how bird ranges have moved over time, conservation efforts can be prioritized in areas that are important for birds today and in a climate-altered future. With two thirds of North American bird species at increasing risk of extinction by the end of this century, Audubon CBC data is more important than ever for effective conservation.
