I love collage work.  For this project I gathered some of my old scrapbook papers for the children to make their pattern owls.  I made tracers out of old file folders as well.  Here's how I made the tracers:

1 large oval tracer for the body  (I had pre-cut construction paper rectangles for tracing the body)
1 small circle tracer for eyes (cut 2)
1 small triangle tracer for ears (cut 2)
1 triangle tracer for beak

I let the children design their own feet for the owls.
We tore pieces of brown construction paper for the tree branches where the owl might be sitting.
