Conduct a
Feeder Watch

If you live in the South Marin Christmas Bird Count circle and want to join this year’s count in the comfort of your home, you can become a feeder watcher! Please email your CBC coordinator HERE if you are interested and want to learn more! Field party participants who live in the count circle are invited to count their feeder birds as well.

Feeder-watchers: Feeder watches must be done on the day of the count which this year is December 31.  “Feeder watchers should look for the maximum number of each species visible (or within earshot) at any one time as their maximum count. They should not just keep adding chickadees for their entire watch period. Feeder watchers also must report the number of hours spent watching their feeders.  Field parties should not tally birds at feeders known to be counted by feeder watchers.  …  Hours spent watching must be reported separately by feeder watchers.”
