Note 20 — NOTES[H] ON CERTAIN BIRDS FOUND IN NORFOLK.

This well describes the Great-crested Grebe, which Browne rightly says comes to us about the month of April. Browne notices the peculiar formation of the tibia in this family of birds, but it had long been known. The next, named Mergus acutirostris cinereus, is most likely the same species in winter plumage. The other birds mentioned are Mergus minor, the Little Grebe or Dabchick, and M. serratus, the Red-breasted Merganser, even now known as the "Saw-bill."
