JACAMAR
, a word formed by See also:Brisson from Jacameri, the Brazilian name of a See also:bird, as given by Marcgrave, and since adopted in most See also:European See also:tongues for the See also:species to which it was first applied and others allied to it, forming the See also:family Galbulidae 1 of ornithologists, the precise position of which is uncertain, since the best authorities differ
.
All will agree that the jacamars belong to the See also:great heterogeneous See also:group called by See also:Nitzsch Picariae, but further into detail it is hardly safe to go
.
The Galbulidae have zygodactylous or pair-toed feet, like the Cuculidae, Bucconidae and Picidae, they also resemble both the latter in laying glossy See also: (A . N.) JAtcANA, the Brazilian name, according to Marcgrave, of certain birds, since found to have some See also:allies in other parts of the See also:world, which are also very generally called by the same appellation . They have been most frequently classed with the See also:water-hens or rails (Rallidae), but are now recognized by many systematists as forming a See also:separate family, Parridae,3 whose leaning seems to be rather towards the Limicolae, as apparently first See also:Pheasant-tailed Jacanae suggested by See also:Blyth, a view which is supported by the osteological observations of See also:Parker (Prot . Zool . Society, 1863, p . 513), though denied by A . Milne-See also:Edwards (Ois. See also:foss. de la See also:France, ii. p. rto) . The most obvious characteristic of this group of birds is the extraordinary length of their toes and claws, whereby they are enak,led to walk with ease over water-lilies and other aquatic See also:plants growing in See also:rivers and lakes . The family has been divided into four genera—of which Parra, as now restricted, inhabits South America; Metopidius, hardly differing from it, has representatives in See also:Africa, See also:Madagascar and the See also:Indian region; Hydralector, also very nearly allied to Parra, belongs to the 2 The singular See also:appearance, recorded by See also:Canon Tristram (Zoologist, p . 3906), of a bird of this species in See also:Lincolnshire seems to require See also:notice . No instance seems to be known of any jacamar having been kept in confinement or brought to this See also:country alive; but See also:expert aviculturists are often not communicative, and many importations of rare birds have doubtless passed unrecorded . a The classic Parra is by some authors thought to have been the golden oriole (see IcTERUS), while others suppose it was a See also:jay or See also:pie .
The word seems to have been imported into See also:ornithology by Aldrovandus, but the See also:reason which prompted See also:Linnaeus to apply it, as he seems first to have done, to a bird of this group, cannot be satisfactorily stated
.
See also:northern portion of the Australian region; and Hydrophasianus, the most extravagant form of the whole, is found in See also:India, See also:Ceylon and See also:China
.
In habits the jacanas have much in See also:common with the water-hens, but that fact is insufficient to See also:warrant the affinity asserted to exist between the two groups; for in their osteological structure there is much difference, and the resemblance seems to be only that of See also:analogy
