See also:KESTREL (Fr. Cresserelle or Crecerelle, O. Fr. Quercerelle and Quercelle, in See also:Burgundy Cristel) , the See also:English name' for one of the smaller falcons . This See also:bird, though in the See also:form of its See also:bill and ' Other English names are windhover and standgale (the last often corrupted into stonegale and stannell) . See also:KESTREL length of its wings one of the true falcons, and by many ornithologists placed among them under its Linnaean name of Falco tinnunculus, is by others referred to a distinct genus Tinnunculus as T. alaudarius—the last being an epithet wholly inappropriate . We have here a See also:case in which the propriety of the See also:custom which requires the See also:establishment of a genus on structural characters may seem open to question . The See also:differences of structure which See also:separate Tinnunculus from Falco are of the slightest, and, if insisted upon, must See also:lead to including in the former birds which obviously differ from kestrels in all but a few characters arbitrarily chosen; and yet, if structural characters be set aside, the kestrels form an assemblage readily distinguishable by several peculiarities from all other Falconidae, and an assemblage separable from the true Falcons of the genus Falco, with its subsidiary See also:groups Aesalon, Hypotriorchis, and the See also:rest (see See also:FALCON) . Scarcely any one outside the walls of an ornithological museum or library would doubt for a moment whether any bird shown to him was a kestrel or not; and See also:Gurney has stated his belief (See also:Ibis, 1881, p . 277) that the See also:aggregation of See also:species placed by See also:Bowdler See also:Sharpe (See also:Cat . Birds Brit . See also:Mus. i . 423–448) under the generic designation of Cerchneis (which should properly be Tinnunculus) includes " three natural groups sufficiently distinct to be treated as at least separate subgenera, bearing the name of Dissodecles, Tinnunculus and Erythropus." Of these the first and last are not kestrels, but are perhaps rather related to the hobbies (Hypotriorchis) . The See also:ordinary kestrel of See also:Europe, Falco tinnunculus or Tinnunculus alaudarius, is by far the commonest bird of See also:prey in the See also:British Islands . It is almost entirely a summer migrant, coming from the See also:south in See also:early See also:spring and departing in autumn, though examples (which are nearly always found to be birds of the See also:year) occasionally occur in See also:winter, some arriving on the eastern See also:coast in autumn . It is most often observed while See also:hanging in the See also:air for a See also:minute or two in the same spot, by means of See also:short and rapid beats of its wings, as, with See also:head pointing to windward and See also:expanded tail, it is looking out for prey—which consists chiefly of mice, but it will at times take a small bird, and the remains of frogs, See also:insects and even earthworms have been found in its See also:crop . It generally breeds in the deserted See also:nest of a See also:crow or See also:pie, but frequently in rocks, ruins, or even in hollow trees—laying four or five eggs, mottled all over with dark brownish-red, sometimes tinged with See also:orange and at other times with See also:purple . Though it may occasionally snatch up a See also:young See also:partridge or See also:pheasant, the kestrel is the most harmless bird of prey, if it be not, from its destruction of mice and cockchafers, a beneficial species . Its range extends over nearly the whole of Europe from 68° N. See also:lat., and the greater See also:part of See also:Asia—though the form which inhabits See also:Japan and is abundant in See also:north-eastern See also:China has been by some writers deemed distinct and called T. japonicus —it is also found over a See also:great part of See also:Africa, being, however, unknown beyond See also:Guinea on the See also:west and See also:Mombasa on the See also:east coast (Ibis, 1881, p . 457) . The See also:southern countries of Europe have also another and smaller species of kestrel, T. tinnunculoides (the T. cenchris and T. naumanni of some writers), which is widely spread in Africa and Asia, though specimens from See also:India and China are distinguished as T. pekinensis . Three other species are found in Africa—T. rupicola, T. rupicoloides and T. alopex—the first a See also:common bird in the Cape, while the others occur in the interior . Some of the islands of the Ethiopian region have See also:peculiar species of kestrel, as the T. newtoni of See also:Madagascar, T. punctatus of See also:Mauritius and T. gracilis of the See also:Seychelles; while, on the opposite See also:side, the kestrel of the Cape Verde Islands has been separated as T. neglectus . The T. sparverius, commonly known in See also:Canada and the See also:United States as the " See also:sparrow-See also:hawk," is a beautiful little bird . Various attempts have been made to recognize several species, more or less in accordance with locality, but the See also:majority of ornithologists seem unable to accept the distinctions which have been elaborated chiefly by Bowdler Sharpe in his See also:Catalogue and R . Ridgway (North See also:American Birds, iii . 159–175), the former of whom recognizes six species, while the latter admits but three— T. sparverius, T. leucophrys and T. sparverioides—with five See also:geographical races of the first, viz. the typical T. sparverius from the See also:continent of North See also:America except the coast of the Gulf of See also:Mexico; T. australis from the continent of South America except the North See also:Atlantic and Caribbean coasts; T. isabellinus, inhabiting See also:continental America from See also:Florida to Fr .
