Friday Feb 13th is Day 1 of the 4-day Great Backyard Bird Count. I highly recommend this as a family activity. It takes as little as 15 minutes per day and it is easy for children to participate. Your kids will be thrilled to know they are helping Audubon and Cornell's Lab of Ornithology–real bird scientists– understand more about our feathered friends.
Print a tally sheet and go to the window (or for a walk, or to the park) to observe and count. You enter your data online, or with this printable form. It is that easy. And, there is even a beautiful certificate that you can print and present to your child when you are done.
