text: Often the eggs are laid on the bare sand or gravel which probably indicates that the nest is a new one, or that the eggs are fresh; oftener, perhaps, the nesting chamber is lined with bits of clean, white fish bones, fish scales, or fragments of the shells of crustaceans; these, I believe, are the remains of ejected pellets and indicate that the nest has been previously occupied by young birds or that the female has been fed on the nest for some time; there is no evidence to indicate that the birds ever bring in such material intentionally.
