Cutoff for registration to assist in the count is Sunday, December 8.
Birders of all skill levels are welcome on the Lisle-Arboretum CBC. The Chicago Ornithological Society (www.chicagobirder.org) sponsors this count where sub-teams are assigned to various locations. Even if you cannot go out in the field, there is another way to contribute: DBC members who live in the count circle can participate as a feeder-watcher.
