Abstract Pelecaniforms face the same formidable problems as many other seabirds and, like them, require active management based on legislation and education, global databases and monitoring, and coordinated international research (see Nettleship 1991; Nettleship and Duffy 1992). Technology offers powerful new tools not only for following

Wing morphology and flight behavior of pelecaniform seabirds
Journal of Morphology, 2007AbstractThe selective pressures associated with flight are significant factors in shaping the morphology of volant forms. Tropical seabirds are of particular interest because of their long foraging bouts, which can last hundreds of kilometers in search of unpredictable (spatially and temporally) resources.

ARBOVIRUSES IN WATER BIRDS (CICONIIFORMES, PELECANIFORMES) FROM FLORIDA
Journal of Wildlife Diseases, 1994Sera from 360 ciconiform and pelecaniform birds collected in Florida (USA) from 1974 to 1990 were tested for serum neutralizing (SN) antibodies to eastern equine encephalitis (EEE), St. Louis encephalitis (SLE), and Everglades (EVE) viruses. Serum neutralizing antibodies to EEE virus were detected in 2%, to SLE virus in 7%, and to EVE virus in none of ...

Ibis, 1983
Electrophoresis of soluble feather keratins was performed in Gradipore gels under two pH conditions. The taxa of two diverse orders, the Pelecaniformes and Cuculiformes, were compared. Dendograms based on identity indices and genetic distances were constructed by the Fitch‐Margoliash and unweighed pair‐group algorithms (UPGMA).

THE PIAGETIELLA (MALLOPHAGA: MENOPONIDAE) OF THE PELECANIFORMES
The Canadian Entomologist, 1970AbstractEight species of the genus Piagetiella are discussed and illustrated. There are two new synonymies: P. africana (Bedford) (= Tetrophthalmus australis Bedford) and P. titan (Piaget) (= Tetrophthalmus subtitan Bedford). A key is given to the species.
