One of my favorite activities is Project Feederwatch, a citizen science project of the Cornell Lab of Ornithology. The season starts the second Saturday in November (November 14). Although I have some feeders up year around, I have several others to clean in preparation for bird feeding season. It's also time to visit Berend Brothers and Atwoods to stock up on seed and suet.
I have participated in varying degrees for many years and enjoy reading the reports at the end of the year.
If you enjoy watching birds at your feeders, this is a fun and low cost ($15/$12 Lab members) activity for the entire family. This would be an educational activity for home schoolers and classrooms.
