GUAINUMBI, in zoology, the name of an American bird, called the bumming bird, and by fome authors tomineus. It is a large genus of birds, many fpecies of it having been de- fcribed by authors, and many which they have not defcribed, having been fent into Europe by the curious. It is the fmalleft of all birds, but of the moft beautiful and lively co- lours of all others. It flies very fwiftly, and in flying makes a noife exactly like the humming of a bee, and is not much larger than the humble bee. It can fuftain itfelf a long time on the wing, and in that pofture thrufts its little beak into flowers, the juices of which it fucks and feeds on. As it has no other food but this, there is no keeping it alive, but all die that are taken ; and they are preferved and fent over as curiofities to us. Many have reported ftrange ftories of their fleeping all the winter months, and reviving at the approach of fpring ; but Marcgrave faw them in great plenty, in the woods in all feafons. The Indians make pictures with the feathers of thefe birds, which are fo brightly coloured, as to vie with the fincft paint, and fo thin as to be as clofe as colours on canvas, Rays Ornithol. p. 165.
The humming bird is fo fmall, that its leg and foot toge- ther meafure but half an inch, and its whole trunk not an inch. The body weighs only T \> of an ounce, which is about equivalent to a filvcr fix- pence ; whereas a titmoufe, the fmalleft bird among us, weighs two millings, or half a crown a . Its neft, which is made of cotton, is much of the fize and figure of the thumb of a man's glove ; its egg about the bignefs of a pea. Some of the Indians wear them in their ears for pendants b .[ — 2 Phil. Tranf. N° 2.00. p. 760. b Phil. Tranf. N° 206. p. 993.—]
