Olson, Storrs L., and Alan Feduccia. Relationships and Evolution of Flamingos (Aves: Phoenicopteridae). Smithsonian Contributions to Zoology, number 316, 73 pages, 40 figures, 2 tables, 1980.—Previous evidence supposedly showing a relationship between flamingos and either storks (Ciconiiformes) or ducks (Anseriformes) is re-examined in light of the recent(More)
Tissue samples from 699 birds from three regions of Asia (Myanmar, India, and South Korea) were screened for evidence of infection by avian parasites in the genera Plasmodium and Haemoproteus. Samples were collected from November 1994 to October 2004. We identified 241 infected birds (34.0%). Base-on-sequence data for the cytochrome b gene from 221 positive(More)
Phylogenetic analysis of 1.35 kb of mtDNA sequence from fossils revealed a previously unknown radiation of Hawaiian geese, of which only one representative remains alive (the endangered Hawaiian goose or nene, Branta sandvicensis). This radiation is nested phylogenetically within a living species, the Canada goose (Branta canadensis) and is related most(More)
Olson, Storrs L., and Alan Feduccia. Presbyornis and the Origin of the Anseriformes (Aves: Charadriomorphae). Smithsonian Contributions to Zoology, number 323, 24 pages, 15 figures, 1980.•Evidence purportedly allying the Anseriformes with the Galliformes is discredited. The discovery of vestigial lamellae in the Anhimidae, in addition to the characters(More)
Albatrosses (Diomedeidae) do not occur in the North Atlantic Ocean today except as vagrants, although five species were present in the early Pliocene. No fossil breeding sites of albatrosses were known previously. The timing of extinction of albatrosses in the North Atlantic was likewise unknown. Deposits that formed near present-day sea level along the(More)
The nene (or Hawaiian goose, Branta sandvicensis) once occurred on most of the main Hawaiian Islands (1), but by Captain Cook’s arrival in 1778, nene were found only on the island of Hawaii (2). A decline that began in the 1800s reduced the nene population to fewer than 30 individuals by the middle of the 20th century (2). Nene currently have extremely low(More)

Smithsonian Contributions to Paleobiology, number 62, 20 pages, 15 figures, 1986.—^Fossils from fluvial deposits of early Oligocene age in Egypt document the earliest known diverse avifauna from Africa, comprising at least(More)
The Hawaiian "honeyeaters," five endemic species of recently extinct, nectar-feeding songbirds in the genera Moho and Chaetoptila, looked and acted like Australasian honeyeaters (Meliphagidae), and no taxonomist since their discovery on James Cook's third voyage has classified them as anything else. We obtained DNA sequences from museum specimens of Moho(More)
Four additional specimens from the Green River Formation of Wyoming are referred to the Eocene frigatebird Limnofregata azygosternon Olson, originally described from a nearly complete skeleton and two partial paratypes. Two skulls with mandibles and a partial postcranial skeleton are described as a new species, Limnofregata hasegawai, characterized by much(More)
—Paleontological and geological evidence suggest that the distinctive endemic skink Eumeces longirostris could potentially be as old as continuously emergent land on the Bermuda seamount (approximately . 1–2 million yr). The species has experienced sustained evolutionary stasis for at least the past 400,000 yr, during which time there has been no(More)
