kite (n.) Look up kite at Dictionary.com
bird of prey (Milvus ictinus), Old English cyta "kind of hawk," probably imitative of its cries (compare ciegan "to call," German Kauz "screech owl"). The toy kite first so-called 1660s, from its way of hovering in the air like a bird. The dismissive invitation to go fly a kite is attested by 1942, American English, probably tracing to the popular song of the same name (lyrics by Johnny Burke), sung by Bing Crosby in "The Star Maker" (1939):
Go fly a kite and tie your troubles to the tail
They'll be blown away by a merry gale,
Go fly a kite and toss your worries to the wind
And they won't come back, they'll be too chagrined.
