Kite Hawk

Kite is the common name for certain birds of prey in the family Accipitridae, particularly in the subfamilies Elaninae and Perninae and certain genera within Buteoninae."kite". Encyclopædia Britannica. Encyclopædia Britannica Online. Encyclopædia Britannica Inc., 2014. Web. 24 Nov. 2014 . The term is derived from Old English , onomatopoeic from the call notes of the buzzard (''Buteo buteo'') and red kite (''Milvus milvus''). The name, having no cognate names in other European languages, is thought to have arisen in England; it apparently originally denoted the buzzard, as the red kite was then known by the widespread Germanic name 'glede' or 'glead', and was only later transferred to the red kite as "fork-tailed kite" by Christopher Merret in his 1667 ''Pinax Rerum Naturalium Britannicarum''. By the time of Thomas Pennant's 1768 ''British Zoology'', the name had become fixed on the red kite, other birds named 'kite' around the world being named from their then-perceived relationship to it.

Some authors use the terms "hovering kite" and "soaring kite" to distinguish between ''Elanus'' and the milvine kites, respectively. The group may also be differentiated by size, referring to milvine kites as "large kites", and elanine kites as "small kites".

Taxonomy and systematics

19th century

In 1824, Vigors proposed five divisions or ''stirpes'' of the family Falconidae: Aquilina (eagles), Accipitrina (hawks), Falconina (falcons), Buteonina (buzzards) and Milvina (kites, containing two genera ''Elanus'' and ''Milvus''). He distinguished the kites as having weaker bill and feebler talons than the buzzards, tail more or less forked, and wings longer than the tail.

In ''Elanus'', he grouped the black-winged kite (now several ''Elanus'' spp.), scissor-tailed kite (now ''Chelictinia''), and swallow-tailed kite (now ''Elanoides''). These species all have pointed wings with the second primary the longest. The pattern of scales on the legs (acrotarsi) is reticulated, and the toes are separated. But Vigors noted that only the black-winged kite had rounded undersides on the nails of its talons, a trait found in the osprey but not in any other raptors, and thus suggested a separation of ''Elanus'' into two sections. A year later, he established a separate genus ''Nauclerus'' for the scissor- and swallow-tailed kites.

''Milvus'' contained the familiar red and black kites. The fourth primary feather is the longest, leg scales are scutellated, and the exterior toe is united to the middle toe by a membrane.

Vigors placed ''Ictinia'', "the ''Milan Cresserelle'' of M. Vieillot" and "the ''Mississippi Kite'' of Mr. Wilson", into Buteonina. Though noting that "the wings are of considerable length, extending far beyond the tail, a character which has induced M. Vieillot and others to place this bird near the ''Kites''", he wrote that the strong affinity in characteristics and manners warranted it to be placed closer to the falcons.

20th century

Swann's 1922 synopsis grouped all the kites together with the "cuckoo-falcons" and honey buzzards into a large Milvinæ subfamily. His order was: ''Elanoides'', ''Chelictinia'', ''Milvus'', ''Lophoictinia'', ''Rostrhamus'', ''Helicolestes'', ''Chondrohierax'', ''Odontriorchis'', ''Gypoictinia'' (=''Hamirostra''), ''Elanus'', ''Gampsonyx'', ''Ictinia'', ''Harpagus'', ''Baza'', ''Aviceda'', ''Henicopernis'', ''Machærhamphus'', ''Pernis''.

In contrast, Peters grouped the large kites into subfamily Milvinae and most small kites into Elaninae, with a few small kites joining the honey-buzzards and bazas in Perninae. His arrangement of kite genera was as follows:

*Elaninae: ''Elanus'', ''Chelictinia'', ''Machaerhamphus''.
*Perninae: ''Elanoïdes'', (''Aviceda'', ''Henicopernis'', ''Pernis'', ''Odontotriorchis''), ''Chondrohierax''.
*Milvinae: ''Harpagus'', ''Ictinia'', ''Rostrhamus'', ''Helicolestes'', ''Milvus'', ''Lophoictinia'', ''Hamirostra'', ''Haliastur''.
*Polyhieracinae: ''Gampsonyx''

The pearl kite ''Gampsonyx'' had variously been placed with the accipiters, forest-falcons, or elanine kites. It was not until the 1960s that a similar moult schedule established its affinity to ''Elanus''.

21st century

By 2015, genetic research showed that many of the kite genera are related to honey-buzzards. Several of the large kites are related more closely to the ''Buteo'' hawks (buzzards) than to other kites and sea-eagles.

Boyd''Taxonomy in Flux checklist
Accipitriformes
' "One thing that genetic results have made clear is that the kites are not a natural group. ... Kites also occur in three clades in Perninae and four clades in Buteoninae. ... Three groups of kites are part of Perninae. The Neotropical Chondrohierax and Leptodon kites, the Swallow-tailed Kite (Elanoides, sister to the Pernis honey-buzzards), and the Square-tailed Kite (Lophoictinia, sister to the Henicopernis honey-buzzards). Note that the honey-buzzards are not a natural group either." places the "true" milvine kites (''Milvus'' and ''Haliastur'') with the sea-eagles in tribe Milvini within Buteoninae. This results in the following arrangement (genera in parentheses are not generally called kites):
*Elaninae: ''Gampsonyx'', ''Chelictinia'', ''Elanus''.
*Perninae: ''Chondrohierax'', ''Leptodon'', ''Elanoides'', (''Pernis''), ''Hamirostra'', ''Lophoictinia'', (''Henicopernis'').
*Buteoninae
**Harpagini: ''Harpagus''.
**Milvini: ''Haliastur'', ''Milvus'', (''Haliaeetus'', ''Icthyophaga'').
**Buteonini: many genera, including the kites ''Ictinia'', ''Rostrhamus'', and ''Helicolestes''.
**:''Ictinia'' is near-basal, after the Old-World genus ''Butastur''. ''Rostrhamus'' and ''Helicolestes'' form a clade with the black-collared hawk (''Busarellus'') and the crane hawk (''Geranospiza'').

As early as 1882, Anton Reichenow had also placed Section Milvinæ alongside Section Buteoninæ in Subfamily Buteoninæ.

In mythology

Isis is said in ancient Egyptian mythology to have taken the form of a kite in various situations in order to resurrect the dead.

It also figures in several fables by Aesop which underline its character as a predator: The Sick Kite, The Kite and the Doves and a variant of The Crow and the Snake.

In pre-colonial Philippine mythology, the Tagalog creation myth begins with a kite, the sea, and the sky. The kite causes the sea and sky to go to war, and after the war, land is formed, allowing the kite to finally land and build a nest.

In Bushongo mythology, Chedi Bumba (third son of the god M'Bombo: the original creator of everything) in his quest to improve upon his father's design; was only able to create the Kite.
