I have one visiting in my yard this year for the first time. I usually have downy, hairy and the occasional pileated so I was thrilled to have another type!
I have always used the Petersen guide, but I would also like to check out the Sibley as I get more into identifying different birds. It is wonderful that you are exploring birds with your daughter. My two adult daughters and I are doing this course "together". They are in CO and I am in NH.
Red-breasted nuthatches, from tree creeper group have been at my feeders this winter. They are tiny but feisty when challenging the chickadees for feeder space!
