HomeField Trips - Events


One to two times each month from October through June, YAAS sponsors a field trip to nearby hot-spots for birding enthusiasts, with occasional out of town trips.  Generally, trips are scheduled on a Saturday. 

Christmas Bird Counts

Christmas Bird Counts are censuses of all birds (all individuals and all species) found in a defined area on a given count day. The count provides population data for use in research and conservation efforts.

Participation in all counts is free, and all are welcome regardless of birding experience.

View the Christmas Bird Count page for additional information about this long-lived Audubon tradition.
