chen hyperboreus. February 22, 1909. I noticed several of the gray back feathers of the young Snow Goose on the ground. It is getting more white fresh feathers in its back. I can see no appreciably change in the color of the bill and feet since last spoken of. February 24, 1909. I received another immature Snow Goose today. It seemed farther along toward the adult plumage than the bird mentioned above. It is a very small bird. Its bill is nearly as bright as that of an adult, although a little duller about the base. The feet, however, are not so brightly colored. March 13, 1909. Of the two immature Snow Geese the one with the pink bill has white tail feathers, while the larger and younger one has dark centers and white edges to its tail feathers. A week or two ago both a young and an old Snow Goose were seen patting the ground with both feet to soften it and then digging into it with their bills; this was when the ground was quite damp.
