Forest Owlet (Heteroglaux blewitti) Science Article 1 abstract Re-evaluation of specimen and literature evidence established that only seven study skins of the Forest Owlet Athene (Heteroglaux) brama were ever collected, and only between 1872 and 1884. Examination of all seven specimens elucidated numerous diagnostic characters as well as the localities at which the species was […]
Rediscovery of the Flores Scops Owl Otus alfredi on Flores, Lesser Sunda Islands, Indonesia, and reaffirmation of its specific status
Flores Scops Owl (Otus alfredi) Science Article 1 abstract The Flores Scops Owl Otus alfredi remained unreported for almost a century after its description in 1897, and skepticism developed regarding its validity as a species. In 1994 a fourth individual (a juvenile) was collected near the type locality, and an adult was independently mistnetted and […]
The taxonomic status of Flores Hawk Eagle Spizaetus floris
Flores Hawk-Eagle (Nisaetus floris) Science Article 1 abstract The Changeable Hawk Eagle Spizaetus cirrhatus complex ranges from India (cirrhatus) through South-East Asia (mainly limnaeetus) to Flores, Sumbawa and Lombok, Indonesia (floris). The latter taxon is morphologically very distinct from the widespread limnaeetus. It has diagnostic white patches on the upperside of the inner parts of […]
Diurnal time-activity budgets in wintering Ferruginous Pochard Aythya nyroca in Tanguar Haor, Bangladesh
Ferruginous Duck (Aythya nyroca) Science Article 1 abstract Diurnal time-activity budgets were quantified for Ferruginous Pochard Aythya nyroca wintering in Tanguar Haor, Bangladesh. Individuals spent most time resting (60%), with less time spent feeding (17%), preening (14%) and swimming (9%). The time spent feeding was generally lower than for other Aythya species in winter, perhaps […]
Pyrrhura orcesi, a new parakeet from southwestern ecuador, with systematic notes on the p. melanura complex
El Oro Parakeet (Pyrrhura orcesi) Science Article 2 abstract A new species of parakeet, Pyrrhura orcesi sp. nov., from southwestern Ecuador is described and named the El Oro Parakeet. This species is most closely related to the Maroon-tailed Parakeet (P. melanura). Pyrrhura orcesi is restricted to a narrow band of forest, between ca 600 to […]

The biology of Dwarf Tinamou Taoniscus nanus, with notes on its breeding in captivity
Dwarf Tinamou (Taoniscus nanus) Science Article 2 abstract Dwarf Tinamou Taoniscus HGHUS was described by Temminck in 1815, based on Azara?s YnambuCarap. Its type-locality is Misiones in Paraguay, not the province of the same name in north-east Argentina, as is often and erroneously assumed. It may be extinct there, with no con?rmed recordssince 1901, although […]
The Dwarf Tinamou (Taoniscus nanus) of Central Brazil
Dwarf Tinamou (Taoniscus nanus) Science Article 1 abstract In the last 5 yr, we have obtained some information on the Dwarf Tinamou (Taoniscus nanus) at the “Reserva Bioligica do Roncador” of the Instituto Brasileiro de Geografia e Estatistica (IBGE) (approx. 15 55’S, 47 52’W), Federal District central Brazil. Except for Azara (1805), the Dwarf Tinamou […]
The feeding ecology and digestive tract morphometry of two sympatric tinamous of the high plateau of the bolivian andes
Darwins Nothura (Nothura darwinii) Science Article 1 abstract We studied the trophic niche breadth and the degree of overlap in the winter diets of two sympatric species of tinamous in the Bolivian Andes, the Ornate Tinamou (Nothoprocta ornata) and the Darwin?s Nothura (Nothura darwinii), by analyzing crop and gizzard contents of birds collected by sport […]
Phylogeny of the cuckoo genus Coccyzus(Aves: Cuculidae): a test of monophyly
Dark-billed Cuckoo (Coccyzus melacoryphus) Science Article 1 abstract Coccyzus comprises nine species of New World cuckoos (Aves: Cuculidae)that breed from southern Canada to central South America. The phylogeny of thisgenus was reconstructed using 2490 base pairs of the mitochondrial genes cytochromeoxidase II and III, and cytochrome b. Maximum likelihood, maximum parsimony,and Bayesian inference approaches produced […]
