Robins and Wrens are lovely little birds, stickey-uppey tail, tiny and delicate:

Quite happy with this model, taken from “More Origami” by Robert Harbin, a book I bought years ago.

This is a fairly manageable manipulation of the bird base but the legs are so tortuously thin that I had to help it stand up with a couple of blutac blobs under the feet, soz.
