bustard: [15] Bustard (the name of a large game bird now extinct in Britain) is something of a mystery word. Old French had two terms for the bird, bistarde and oustarde, both of which come from Latin avis tarda, literally ‘slow bird’ (Latin tardus gave English tardy [15]). This, according to the Roman writer Pliny, was what the bird was called in Spain.

It has been objected that the bustard can run quite fast, and that the name avis tarda must be some sort of folk-etymological alteration of a non-Latin word; but in fact the bird’s normal gait is a fairly slow and stately walk, so the term is not so far-fetched. The English word is presumably a blend of the two Old French ones, perhaps via an Anglo-Norman *bustarde.

bird (n.1)youdaoicibaDictYouDict
Old English bird, rare collateral form of bridd, originally "young bird, nestling" (the usual Old English for "bird" being fugol, for which see fowl (n.)), which is of uncertain origin with no cognates in any other Germanic language. The suggestion that it is related by umlaut to brood and breed is rejected by OED as "quite inadmissible." Metathesis of -r- and -i- was complete 15c.
Middle English, in which bird referred to various young animals and even human beings, may have preserved the original meaning of this word. Despite its early attestation, bridd is not necessarily the oldest form of bird. It is usually assumed that -ir- from -ri- arose by metathesis, but here, too, the Middle English form may go back to an ancient period. [Liberman]
Figurative sense of "secret source of information" is from 1540s. Bird dog (n.) attested from 1832, a gun dog used in hunting game birds; hence the verb (1941) meaning "to follow closely." Bird-watching attested from 1897. Bird's-eye view is from 1762. For the birds recorded from 1944, supposedly in allusion to birds eating from droppings of horses and cattle.
