. Life histories of North American petrels and pelicans and their allies; order Tubinares and order Steganopodes . argest single colony of youngis on the south side of the lagoon, where the ground has been leveled off inpast years by phosphate-rock diggers. Here from a little eminence one canlook off and see many thousands of birds at a glance, but it would be hazardousto guess how many there are on the whole island. Dr. T. W. Richards (1909) describes the nest as follows: Regarding the nesting habits. Dr. Campbell noted an interesting point ofdifference in the two species; both lay in slight hollows scratched in thebare sand, but immutabilis usually heaps up this material in a ridge aroundthe nest. He says the bird, sitting on the nest and reaching out as faras possible, picks up sand in its bill and deposits same around the edge until itis built up four or five inches. I noticed the difference in contour of nestsof the two species, and as a white pair (Laysan) made a nest just beyondmy door I was enabled to discover how it was done. The building up of the U. S.
