Length to end of tail 44 1/2 inches, to end of claws 59 1/2, to end of wings 46 1/2; from flexure 18; tail 6; extent of wings 62; bill along the back 9 1/2, along the edge 9, its greatest depth 2 1/4; bare part of tibia 6; tarsus 9; middle toe 4 2/12, its claw 3/4. Weight 11 3/4 lb.

The Female is precisely similar to the Male, differing merely in being smaller. Its weight is 9 1/4 lb.

The Young are dusky grey all over, the quills and tail brownish-black. The head all covered with down, excepting just at the base of the bill. After the first moult, the bare space extends over the head and cheeks; the downy feathers of the hind head and neck are dusky; the general colour of the plumage is white, the quills and tail nearly as in the adult, but with less gloss. A Male of this description shot in January was in length 35 inches, its bill 7 1/2, tarsus 7, middle toe 4, its claw 1/2; its weight 7 3/4 lb.

When the Wood Ibis has caught a fish too large to be easily swallowed, it shakes its head in a violent manner, as if to force its prey down or drive it up again. In the latter case, it carries the fish to the shore, and breaks it into pieces, which it then swallows.

This species has the subcutaneous cellular tissue highly developed, especially along the breast, and the lower parts of the body, although not by any means so much so as in the Brown Pelican. I have represented a flock of these birds in the back ground, with the view of giving you an idea of the swamps to which they usually resort. They are on the edge of an alligator’s hole, at their avocations. The trees, clad with dangling mosses, afford evidence of the insalubrity of the atmosphere. You see the alligators with their heads and backs above water, watching the motions of the birds.

LOUISIANA HERON.

Ardea Ludoviciana, Wils.
PLATE CCXVII. Male.

Delicate in form, beautiful in plumage, and graceful in its movements, I never see this interesting Heron, without calling it the Lady of the Waters. Watch its motions, as it leisurely walks over the pure sand beaches of the coast of Florida, arrayed in the full beauty of its spring plumage. Its pendent crest exhibits its glossy tints, its train falls gracefully over a well defined tail, and the tempered hues of its back and wings contrast with those of its lower parts. Its measured steps are so light that they leave no impression on the sand, and with its keen eye it views every object around with the most perfect accuracy. See, it has spied a small fly lurking on a blade of grass, it silently runs a few steps, and with the sharp point of its bill it has already secured the prey. The minnow just escaped from the pursuit of some larger fish has almost rushed upon the beach for safety; but the quick eye of the Heron has observed its motions, and in an instant it is swallowed alive. Among the herbage yet dripping with dew the beautiful bird picks its steps. Not a snail can escape its keen search, and as it moves around the muddy pool, it secures each water lizard that occurs. Now the sun’s rays have dried up the dews, the flowers begin to droop, the woodland choristers have ended their morning concert, and like them, the Heron, fatigued with its exertions, seeks a place of repose under the boughs of the nearest bush, where it may in safety await the coolness of the evening. Then for a short while it again searches for food. Little difficulty does it experience in this; and at length, with the last glimpse of day, it opens its wings, and flies off towards its well-known roosting-place, where it spends the night contented and happy.

This species, which is a constant resident in the southern parts of the peninsula of the Floridas, seldom rambles far from its haunts during the winter season, being rarely seen at that period beyond Savannah in Georgia to the eastward. To the west it extends to the broad sedgy flats bordering the mouths of the Mississippi, along the whole Gulf of Mexico, and perhaps much farther south. In the beginning of spring, it is found abundantly in the Carolinas, and sometimes as far east as Maryland, or up the Mississippi as high as Natchez. You never find it far inland: perhaps forty miles would be a considerable distance at any time of the year. It is at all seasons a social bird, moving about in company with the Blue Heron or the White Egret. It also frequently associates with the larger species, and breeds in the same places, along with the White Heron, the Yellow-crowned Heron, and the Night Heron; but more generally it resorts to particular spots for this purpose, keeping by itself, and assembling in great numbers. Those which visit the Carolinas, or the country of the Mississippi, make their appearance there about the first of April, or when the Egrets and other species of Heron seek the same parts, returning to the Floridas or farther south about the middle of September, although I have known some to remain there during mild winters. When this is the case, all the other species may be met with in the same places, as the Louisiana Heron is the most delicate in constitution of all. Whilst at St Augustine in Florida, in the month of January, I found this species extremely abundant there; but after a hard frost of a few days, they all disappeared, leaving the other Herons, none of which seemed to be affected by the cold, and returned again as soon as the Fahrenheit thermometer rose to 80°. There they were in full livery by the end of February, and near Charleston by the 5th of April.

Although timid, they are less shy than most other species, and more easily procured. I have frequently seen one alight at the distance of a few yards, and gaze on me as if endeavouring to discover my intentions. This apparent insensibility to danger has given rise to the appellation of Egrette folle, which is given to them in Lower Louisiana.
