“ No one who knows the self-forgetting devotion with which the birds brood will be surprised that it is possible to come so near an eider-duck sitting in her nest, but it may well excite the astonishment of even an experienced naturalist to learn that the duck suffers one to handle the eggs under her breast without flying away, and that she does not even allow herself to be diverted from her brooding when one lifts her from the nest and places her upon it again, or lays her on the ground at some little distance in order to see the charmingly quaint way in which she waddles back to her brood. ”
