Since the early 2000s there is consensus that they are species in their own right. They are the only members of their genus and both are monotypic.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S.

George Newbold Lawrence
George Newbold Lawrence (October 20, 1806 – January 17, 1895) was an American businessman and amateur ornithologist. Early life Lawrence was born in the city of New York on October 20, 1806. From his youth, Lawrence was a lover of birds and spent much of his spare time studying their habits. At sixteen years of age, he became a clerk in his father's business, becoming a partner in his father's house by age twenty. Career Lawrence conducted Pacific bird surveys for Spencer Fullerton Baird and John Cassin, and the three men co-authored ''Birds of North America'' in 1860. He sold his collection of 8,000 bird skins to the American Museum of Natural History in 1887. Fellow ornithologists honored him by naming one bird genus and 20 species after him, including both the scientific and common name of the Lawrence's goldfinch, first described by Cassin in 1852. Personal life Lawrence died on January 17, 1895 in New York City. His funeral was held at his residence, 45 East 21st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of The Ecuadorian Andes
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bi ...

Urosticte
The whitetips are a small group of hummingbirds in the genus ''Urosticte'', which are restricted to humid forests growing on Andean slopes in north-western South America. Their common name, whitetips, refers to the conspicuous white tips on the central rectrices of the males. As the central rectrices are shorter than the outer, it appears as a large white spot on the central uppertail. Females, which have green-spotted white underparts, lack the white tips to the central rectrices, but instead have broad tips to the outer rectrices (white "tail-corners"). In this genus, the taxon ''intermedia'' has been considered a distinct species, or alternatively an intermediate between ''U. benjamini'' and ''U. ruficrissa'', leading to these being considered conspecific. At present, ''intermedia'' is considered a variant and junior synonym of ''ruficrissa'', resulting in two monotypic species being recognized: Species The genus contains two species.
