Birds -- North America
H. HERODIONES. Tibiæ naked below. Legs and neck much lengthened
in corresponding ratio. Toes long, slender, never coherent at
base, where cleft, or with movable basal webbing. Hallux (as
compared with that of the preceding and following group)
lengthened, free, and either perfectly incumbent or but little
elevated, with a large claw, giving a foot of insessorial
character. Wings commonly obtuse, but broad and ample, without
marked re-entrance on posterior border, the intermediate
remiges not being much abbreviated. Tail short and
few-feathered. Head narrow, conico-elongated, gradually
contracting to the large, stout base of the bill; the loral and
orbital region, or the whole head, naked. Gape of the bill
deeply fissured; tip usually acute; tomia hard and cutting.
Bill conico-elongate, always longer than the head, stout and
firm. Nostrils small, placed high up, with entirely bony and
horny, or only slightly membranous, surroundings. Pterylosis
nearly peculiar in the presence, almost throughout the group,
of powder-down tracts, rarely found elsewhere; pterylæ very
narrow. Palate desmognathous. Carotids double. Altricial.
Comprising the Herons, Storks, Ibises, etc. (not Cranes).
Species usually of large stature, with compressed body and very
long S-bent neck; perching and nesting usually in trees,
bushes, or other high places near water; young hatching weak,
scarcely feathered, and reared in the nest.
I. ALECTORIDES.[12] Tibiæ naked below. Neck, legs, and feet
much as in the last group, but hallux reduced and obviously
elevated, with small claw, the resulting foot cursorial
(natatorial and lobate in _Fulica_). Wings and tail commonly as
in _Herodiones_. Head less narrowed and conic than in the last,
fully feathered or with extensive baldness (not with definite
nakedness of loral and orbital regions). Bill of various shape,
usually lengthened and obtuse, never extensively membranous.
Rictus moderate. Nostrils lower than in _Herodiones_.
Pterylosis not peculiar. Palate schizognathous. Carotids
double. Nature præcocial and ptilopædic. Comprising the Cranes
and Rails and their allies; the former agreeing with the
_Herodiones_ superficially in stature, etc., but highly diverse
in the schizognathous palate, præcocial nature, etc.
