- n.pl. An artificial group of passerine birds having slender bills, as the humming birds.
from The Century Dictionary and Cyclopedia
- A very extensive and unnatural assemblage of chiefly passerine or insessorial birds in winch the beak is slender, as creepers, nuthatches, honey-eaters, sun-birds, humming-birds, hoopoes, and many others having little real affinity: correlated with Dentirostres, Conirostres, etc., in some of the older systems, as that of Cuvier. By Blyth (1849) the term was restricted to the swifts and humming-birds.
- In ornithology, in Sclater's system of 1880, a group of laminiplantar oscine Passeres, nearly conterminous with Sundevall's Cinnyrimorphæ.
Sorry, no etymologies found.
In the conirostres are the perfections which belong to the incessores as an order, with the conspicuous external feature of a comparatively small notch in their bills; in the dentirostres, the notch is strong and toothlike, (hence the name of the tribe) assimilating them to the raptores; the fissirostres come into analogy with the natatores in the slight development of their feet and their great powers of flight; the tenuirostres have the small mouths and long soft bills of the grallatores.
