Shearwater (genus: Puffinus) added to the LRT

are small, extant, pelagic (ocean-going) birds. Newell’s shearwater (Puffinus newelli; Henshaw 1900; 33 cm in length) is shown below (Fig. 1). In the large reptile tree (LRT, 1196 taxa) it nests with the giant, toothed pelagic bird, Pelagornis.

The Procellariiifornes
are the tube-nosed birds: petrels, storm petrels, shearwaters and albatrosses. They are colonial, monogamous and lay a single egg once a year. They range in size from a one-foot to a 22-foot wingspan. The tube nose aids in olfaction. Salt glands remove salt from the water they ingest.
