FALCON (OF. faucon, falcon, It. falcone, from Lat. faleo, falcon, from fal.r, sickle). Broadly, any hawk of the family Faleonithe, more usually and scientifically one of those species which, in the language of falconry, were styled 'noble' birds of prey. The true falcons are char acterized by a bill curved from the base, the upper mandible hooked at the point, and the cut ting edge of the upper mandible furnished with a prominent projection or 'tooth.' The claws are also sharp, curved, and strong; and in accordance with all this powerful armature the whole frame is very robust and muscular. The legs are rather short, and have great power in striking or seizing prey. The breast-bone and shoulder-girdle are large and adapted for the attachment of powerful muscles; the wings are long and pointed. The true falcons are bolder in proportion to their size than any other of the Faleonida•, even the eagles. Their acuteness of vision is wonderful, and they have very great powers of flight. A falcon is recorded as having traversed the distance between Fontainebleau and Malta, not less than 1350 miles, in 24 hours. They soar to a prodigious height in the air, always endeavoring to outsoar any bird of which they may he in pursuit, and to swoop down upon it from above: although it is far more difficult for them to rise vertically in a calm atmosphere than for birds of short and rounded wing, and they either rise obliquely— often making their onward flight in a series of ares—or avail themselves of the wind, and by flying against it are borne aloft as a hoy's kite is.
The species are numerous and widely distrib uted. Some of them are of very wide range, while others are peculiar to certain countries or climates. The best-known American species are Inc gyrfalcon (q.v.), formerly confused with the Iceland falcon and the arecnland falcon, and the peregrine falcon, known in the United fitates as dnek-hawk, of which the female is par ,srellcnce 'the falcon' of falconers, and the male is the 'tercel.' tiercel.' or 'tereelet.' The hobby (Fiden slibbutco) ; the red-footed or red-legged falcon (Falco rufipcs), a small species, much re sembling the hobby; the merlin (!Falco msafon ; and the kestrel or windhover (PaIca tinnuncu las), are common and well-known English species. The gyrfalcon and peregrine are Euro pean also. The name falcon is sometimes ex tended to cover all of the various birds included in the Falconid, some 350 species, of which about one-tenth occur in the United states. The birds commonly called buzzards, eagles, kites, hawks, harriers, ospreys, and caracaras (qq.v.) are usually included in that family, hut it is ob viously confusing to call them all falcons, and the word is better restricted therefore to the genus Falco, in its present restricted sense.
