white, marked on each side with a row of black tears 5 [dorsal plumage rounded in the young, pointed after the 
first moult, and much elongated and narrowed in the adult, all the feathers having a crape-like appearance, devoid 
of gloss, but rich in colouring. Both sexes alike.] A large bird, very noxious on account of the quantity of fish 
it destroys, and formerly celebrated for the sport which it afibrded to falconers. [It breeds, like most of the 
genus, on the branches of high trees, many nests together, which are termed Heronries ; seizes its prey by an 
instantaneous stroke of the bill, transfixing it if large ; watches for it motionless ; emits a loud cry or honk, and 
flies buoyantly : characters which mostly apply to the genus generally.] ! 
We have also another species, the Purple Heron (A. pnrpurea) [smaller and more slender, with longer toes, like 
those of a Bittern. It breeds on the ground, and is rare in the British islands. Colour altogether more reddish.] 
Certain small species with shorter legs are termed Dwarf-bitterns [the Ardeola, Bonap. They are in every 
respect true Bitterns, and resemble that of North America in immature plumage, acquiring a garb analogous to 
that of the Night-herons when adult.] There is one common in the mountainous districts of France {Ard. minuta 
and danubialis, Gm.), which is scarcely larger than a Rail, and fulvous, with the calotte, back, and quills, black. 
It frequents the vicinity of ponds. 
The Tiger-bitterns conjoin to the contour of the Dwarf-bitterns the stature of a Heron and the plumage of the 
ordinary Bitterns. 
Egrets are Herons, the feathers of which, on the lower part of the back, at a certain epoch are lengthened and 
thinly bai’bed. [They are mostly pure white.] One of the handsomest of them, the Heron-crested Egret (A. gar- 
zetta, Lin.), is entirely white, with the dorsal plumage not extending beyond the tail, [and a long occipital crest of 
narrow feathers, resembling in shape those of the Common Heron. It is peculiar to the eastern continent]. Also 
the European Great Egret {A. alba and egretta), likewise wholly white, and the thinly-barbed dorsal plumage 
prolonged beyond the tail. [There are numerous others, in every part of the world. A third in Europe is the 
Bulf backed Heron or Egret (A. russata), with a shorter and smooth yellow bill, longer toes, and coloured dorsal 
plumage in the adult, like the next species.] 
We approximate to the Egrets the Squacco Heron {A. comata and ralloides), a bird of the south of Europe, with 
a russet-brown back, the belly, wings, and tail, white. The adult has a yellowish neck, [densely clad like that of a ^ 
Bittern], and a long [striped] occipital crest : [the toes are also long, and the lengthened dorsal plumage of this 
and the last species are of a hair-like texture, besides resembling in colour. The present species occurs less 
unfrequently in the British Isles than either of the three last.] 
Bitterns have the feathers of the neck lax and separated, which increases their apparent size, [at least when they 
erect them, which they have the power of doing to their whole clothing plumage]. They are commonly rayed or 
speckled, [and not so high on the legs]. 
The European Bittern (A. stellaris) is bright fulvous or clay-colour, mottled and speckled with blackish, and 
has green bill and feet. It is found among the reeds, whence it emits its terrific voice, which has caused it to be 
designated Bos-taurus. [This bird is not rare in Britain, runs wfith great celerity like a Rail, flies also with 
unwillingness, and with its legs hanging, during the day, and when surprized puffs out its plumage in an extra- 
ordinary manner, and strikes with its spear-like bill. In the evening it rises to a vast height in the air, in spiral jj 
ch'cles, occasionally in its flight : it breeds among aquatic herbage in the marshes, and lays eggs of a 
dark brown colour.] 
The Night-herons, with the same port as the Bitterns, have the beak proportionally much thicker, and some f 
slender feathers [three in number] growing from the occiput of the adult. One only inhabits Europe {A. nycti- ^ 
corax, Lin.), the male of which is whitish, with the calotte and back black ; the young brown above spotted with 
whitish, and the calotte dusky. [It is rare in Britain.] 
In fine, we should remark that these different subdivisions of the genus of Herons are of trivial import, and by 
no means well defined. [Together with the Boatbills, they constitute a perfectly distinct group, strongly charac- 
terized by their anatomy, and particularly by the single minute coecum, and the number of cervical vertebra^; 
— seventeen.] ■'B' 
The third tribe, besides having a stouter and smoother beak, has tolerably strong and nearly ; i 
equal membranes between the bases of the toes. 
The Storks {Ciconia, Cuv.) — 
Possess a thick bill, moderately cleft, without any fossa or groove, and the nostrils pierced towards 1 
the back and base ; also an extremely short tongue. Their legs are reticulated, and the front toes 1 
strongly palmated at base, more particularly the outer. Their large and thin mahdibles, by striking > i 
against each other, produce a clattering noise, which is almost the only sound these birds ever make, f 
Their gizzard is slightly muscular, and their two coeca so small as to be barely perceptible. Their inferior 
larynx has no muscle proper ; and the bronchi are longer and composed of more entire rings than usual. 
We have two species in France. 
The White Stork (A. ciconia, Lin.).— Wliite, with black quill- feathers, and red bill and feet ; a large bird, which 
the people hold in particular respect, doubtless originating from its utility in destroying Snakes and other noxious 
animals. It nestles by preference on towers and chimney-stacks, returning to the same every spring, after having 
passed the winter in Africa. [The reason that this species is not common in Britain, is that every pair are shot 1 
soon after making their appearance, which prevents the founding of a colony.] ;
