The Peregrine Falcon
(F. Peregrinus) of Europe and portions of Asia may be taken as typical of another group (subgenus Rhynchodon) of Falcons, in which the tarsus is often shorter, and is never much longer, than the middle toe, while the first quill is longer than the third.
Duck Hawk
In North America its place is taken by two subspecies, the Duck-Hawk (F. peregrinus anatum) and Peale's Falcon (F. p. pealei).
Peale's Falcon
Peale's Falcon is found on the Aleutian Islands, from which point it extends west to the Commander Islands and south along the Pacific coast to Oregon.
Merlin
As typical of another subgenus (AEsalon) of Falcons we may select the Merlin (F. Regulus) of Europe and northern Asia, a bird one third less than the size of the Peregrine.
Pigeon-hawk
The nearest relative of the Merlin is the well-known Pigeon-Hawk (F. columbarius) of North America, which takes its name from its resemblance to the Wild Pigeon...
The Aplomado Falcon
(F. Fusco-Coerulescens), or Orange-chested Hobby, as it is sometimes called, is a handsome Falcon of Central and South America...
Kestrels
The small Falcons known as Kestrels form a group of nearly twenty species and are found with limited exception over the entire globe.
Sparrow Hawk
In North America the place of the Kestrel is filled by the so-called Sparrow Hawk (F. Sparverius), which is probably the best known as well as the smallest and one of the handsomest of our Hawks.
Falconets
Differing from the true Falcons very greatly in point of size, and structurally in having oval nostrils, are the curious little Pygmy Falcons, or Falconets (Microhierax)...
Carrion Buzzards
The second subfamily, embracing the so-called Carrion Buzzards (Polyborince), is less numerous in genera and species than is the last, and may be known by having three or more of the outer primaries with their inner webs cut...
Caracaras
The Caracaras (Polyborus), of which four species are now known, may be regarded as typical of the subfamily, the characters of which have been set forth on page 212.
The Carancho
(P. Tharus) is a closely allied species found from Brazil and Amazonia throughout South America to the Straits of Magellan, being especially abundant in Argentina...
Chimango Hawk
Passing over the genus, Phalcobcenus, with its four or five species, we may mention briefly the Chimango Hawk (Milvago Chimango) as typical of another genus.
Red-throated Falcon
One of the most remarkable members of the Polyborince is the Red-throated Falcon (Ibycter americanus), a bird of very striking appearance on account of the bright red color of the naked skin of the face and throat...
The Tropical Goshawks
The subfamily Micrasturine comprises only the genus Micrastur with about eight species which range quite widely over Central America and northern South America.
The Laughing Or Crying Falcon
(Herpetotheres cachinnans), as it is variously called in allusion to its peculiar notes, is not only the sole tenant of its genus, but is the only known member of the present subfamily Herpetotherince.
Kites, Buzzards, Eagles, Hawks, And Allies
The Kites, Buzzards, Eagles, Harriers, Hawks, and their allies, comprise the second of the two families (the Buteonidae) into which the Accipitres are divided...
The Kites (subfamily Elanince)
A considerable number of accipitrine birds are known, and properly so, as Kites, since they possess at least the common character of lightness, ease, and grace on the wing that is the common property of but few birds.
Black-winged Kite
The best known Old World species is the Black-winged Kite (E. coeruleus), a much smaller bird than the last, being only a little more than thirteen inches long.
The Letter-winged Kite
(E. Scriptus) of Australia is so named from the fact that there is a black mark on the under surface of the wing...
Andersson's Pern
The only other bird of this subfamily that will be mentioned, and this but briefly, is Andersson's Pern (Machoerhamphus anrierssoni) of southwest Africa and Madagascar.
The Honey Buzzards
(Pernis), so called from their especial fondness for the comb and larva of bees and wasps, are typical of the second subfamily, the Pernince.
The Bazas
Much smaller and quite different in some respects from the last are the Bazas, although the points of resemblance to them are so important that they are regarded as belonging to the same subfamily.
Swallow-tailed Kite
Although there is perhaps some doubt as to the correctness of the reference of our Swallow-tailed Kite (Elanoides Forficatus) to this subfamily...
The Ospreys (subfamily Pandionince)
There has been a great deal of discussion as to the proper systematic position of the Ospreys ( Pandion), and even now their status can hardly be regarded as definitely settled.
