Hang up the birds to dry, then draw and glue details on the birds.
This can take about 30 minutes, depending on how wet the birds are, so plan another activity or read a book while this happens.
Once the birds are dry, the kids can draw an eye, wing or other details on the birds. They can use the glue stick to attach legs and a beak. Older children might be able to design their own legs, beaks and wings from construction paper, but for younger children, it's enough challenge just to use the glue stick.
If the kids want, they can also use child-friendly scissors to cut small "feathers" in the tail.
