My two year old daughter was digging in her sandbox the other day when she said, "Hey! There's a feather in here!" I asked her to show me and she held up a maple seed. We used to call them helicopters because of the way they spin down to the ground, but I realized they do look a little like feathers.
Red Leaf, Yellow Leaf is a perfect tie in because Lois Ehlert uses watercolor collages with actual seeds and roots to illustrate a story about the life cycle of a tree.
If you wanted to focus on the bird aspect of the project Kevin Henkes' Birds is a great read for preschoolers. We checked this out from the library and my kids asked for it over and over again.
