According to the U.S. Fish and Wildlife Service, the Christmas Bird Count is one of the world’s oldest and longest running citizen science efforts. It began out of a barbaric practice, known as side hunts, where families would go into the forest and see who could kill the most birds.
Frank Chapman, an early Audubon Society member, proposed the idea of counting birds instead of killing them. He organized 27 observers in 25 places, both the U.S. and Canada, to count all the birds they could on Christmas Day 1900. According to Wikipedia, 90 bird species were observed and 18, 500 individuals were counted that day.
Since then, the counts have been held every December/January with more than 50,000 observers in about 2,000 locations across 17 countries. The data from each count is submitted to the National Audubon Society which helps inform population counts and conservation practices.

Counts can be held on any day from December 14 to January 5. Individual counts are done in a “count circle” with a diameter of 24 kilometers. Each circle has a “compiler” and at least 10 volunteers. Some volunteers follow assigned routes within the circle that remain essentially the same each year. Others count all the birds they see on their backyard feeders from the comfort of their homes.
For many years BEA member Bob Noble has been organizing a Christmas Bird Count in a count circle that covers the eastern half of Brampton and parts of Vaughan, King and Caledon including, Tullamore, part of Caledon East, and all of Bolton. Bob is an amazing naturalist and nature photographer. You’ve likely seen some of his incredible insect pictures posted on Facebook, Instagram, and on his own website . Each year a selection of Bob’s best shots are compiled into a calendar which is published and given to City of Brampton and Toronto and Region Conservation Authority volunteers.

Bob describes the December 15, 2024 count. “The temperature stayed around freezing for the day with a bit of light snow. The smaller ponds were completely frozen but there was some open water in the larger lakes. Thirty field observers and seven feeder watchers managed to count 10,859 individual birds. This is below the average of about 12,000.
We set a new species record of 62 with the previous record being 61 even though the general consensuswas that it was a tough day to find birds. We didn’t find any new species this year leaving the total number of species observed in all counts at 120. Good birds included Green-winged Teal (3rd record), Bald Eagle (3rd record), Yellow-bellied Sapsucker (3rd record) and White-crowned Sparrow (4th record). Record high numbers were recorded for Common Goldeneye (6), Cooper’s Hawk (10), Red-bellied Woodpecker (18), Merlin (3), Eastern Bluebird (6) and Northern Cardinal (180).
A number of regular species were missed including Ruffed Grouse (34 previous counts), Pine Siskin (33 previous counts), Snow Bunting (33 previous counts) and Swamp Sparrow (27 previous counts). Low numbers were recorded for Wild Turkey (2), Rough-legged Hawk (1), Cedar Waxwing (22) and Common Redpoll (1).”
Thanks to Bob for organizing and being a compiler for this important annual event!
