(vertebrate zoology)
An order of oceanic birds characterized by tubelike nostril openings, webbed feet, dense plumage, compound horny sheath of the bill, and, often, a peculiar musky odor.

an order of sea birds. The ends of their beaks are bent into hooks. The nostrils open into special tubes on the beak (whence their second name, tube-nosed swimmers, Tubinares). The feet are webbed, the wings are long and sharp, and the plumage is thick and dense. The body length is from 15 cm (petrels) to 105 cm (albatrosses).

The birds fly and swim well, and certain species of Procellariiformes are good divers. Their peculiar wing structure allows them to soar for hours over the sea without a single wing movement. On land the birds (except for albatrosses) move with difficulty and remain on dry land only in the breeding period. During the rest of the year they make long migrations, such as around Antarctica or from subantarctic regions to the Bering Sea. They are monogamous. Small species begin to reproduce in their second or third year; the larger species, in their fifth to tenth year, after which they do so yearly. They nest in colonies, sometimes far from the sea. There is one egg per clutch. Albatrosses build nests, while other species lay their eggs on the ground, in burrows, or in fissures. Both parents brood. The chicks are blind and covered with thick down. The chicks of the smaller species stay in the nest about 60 days, while those of the albatross stay about six months. They get their food (marine invertebrates, fish, fishing offal) in the upper waters. Only some of the Procellariiformes (the Pelecanoides) are capable of diving.

There are 24 genera of Procellariiformes, uniting 94 species. They are distributed largely in the southern hemisphere. There are 13 species in the USSR, of which four nest. The fork-tailed petrel and Leach’s petrel (Oceanodrama furcata and O. leucorrhoa) nest in the Komandorskie Islands and Kuril Islands, Swinhoe’s petrel (O. monorhis) nests near Vladivostok, and the fulmar (Fulmarus glacialis) nests on the shores of the Barents and Bering seas. Encountered during migrations are the Manx shearwater (Puffinus puffinus) in the Black and Azov seas and the slender-billed shearwater (P. tenuirostris), sooty shearwater (P. griseus), short-tailed albatross (Diomedea albatrus), and black-footed albatross (D. nigripes) in the Pacific.

The flight of petrels and albatrosses (Procellariiformes), observed in South Georgia and its vicinity.
Procellariiformes (petrels and albatrosses) have several life history traits that simplify the study of sex differences in parental investment in male or female offspring.
The seabirds sampled in this study belong to the orders Procellariiformes (albatrosses, petrels, shearwaters, priors, and fulmarines) and Sphenisciformes (penguins).
Se han identificado cinco posibles fuentes de cefalopodos para los procellariiformes: 1) mortalidad cefalopodos post-desove, 2) calamares no reutilizados como carnada, 3) cefalopodos de migracion nictimeral, 4) regurgitacion de cetaceos, y 5) contenidos estomacales de peces eviscerados capturados por buques palangreros (Croxall & Prince, 1994; Vaske, 2011).
Recent studies relating feeding rhythm and body condition of individual parents have demonstrated that pelagic Procellariiformes (albatrosses and petrels) have specific feeding rhythms; the parents alternate or mix short and long foraging trips (Chaurand and Weimerskirch 1994, Weimerskirch et al.
The data include species from the orders Sphenisciformes, Procellariiformes, Pelecaniformes, Falconiformes, Charadriiformes, Strigiformes, Apodiformes, Coraciiformes, and Passeriformes.

We examine relationships among at-sea metabolism, flight characteristics, and weather conditions, and suggest that wind speed plays a critical role in determining foraging costs of Northern Fulmars and that this effect may have major implications both for the ecology of Northern Fulmars, and more generally for Procellariiformes and other flap-gliding seabirds.
Suggestions for discussion by the editors for a future edition include a few additional words in the Index: Boy Scouts/Girl Scouts, Euphausia superba (oddly enough, not mentioned anywhere in the book), Procellariiformes, and tube-nosed.
Due to small sample sizes, I was unable to use multiple regression analysis on the family level, so I analyzed data on the order level for Procellariiformes and Charadriiformes, which were used by Klaassen and Drent to show a positive correlation between metabolic rate and growth rate.
