Ornithological Biography

The Yellow-crowned Heron, which is one of the handsomest species of its tribe, is called \\\"Cap-cap\\\" by the Creoles of Lower Louisiana, in which country it is watched and shot with great eagerness, on account of the excellence of its flesh. It arrives about New Orleans toward the end of March, and departs in the middle of October. On arriving, they throw themselves among the thickets along the bayous, where they breed. Like the Night Heron, this species may be enticed near by imitating its cries, when it approaches, cutting many curious zigzags in the air, and alights close by. It is a curious circumstance that when massing over several gunners placed on the watch for them, they dive toward the ground if shot at and missed, and this they do several times in succession, according to the number of shots. It is in the evening and at dawn that they are chiefly obtained. They are said not to travel in boisterous weather, or when there is thunder; and I have heard the same stated with regard to the Night Heron.

In some parts of the Southern States, this species is quite abundant, while in the intermediate tracts it is seldom or never met with. Thus, in the Floridas, I found great numbers on a bayou near Halifax river, but afterwards saw none until I reached one of the keys, more than two hundred miles distant, and farther south, where it was breeding in society. The first of these flocks I saw in winter, the other on the 22nd of May. Again, while proceeding toward the Texas, we saw a few on an island in Bay Blanche, but met with none afterwards until we reached Galveston Island, where they were plentiful. They seldom advance eastward far beyond North Carolina, and I am not aware of any having been seen farther than New Jersey. On the other hand, they are not generally found on the Mississippi beyond Natchez, although stragglers may sometimes be seen farther up.

This species is by no means entirely nocturnal, for I have seen it searching for food among the roots of mangroves at all hours of the day, and that as assiduously as any diurnal bird, following the margins of rivers, and seizing on both aquatic and terrestrial animals. Whilst at Galveston, I frequently saw a large flock similarly occupied. When they had satisfied their hunger, they would quietly remove to some safe distance toward the middle of an island, where, standing in a crouching posture on the ground, they presented a very singular appearance. That they are able to see to a considerable distance on fine clear nights, I have no doubt, as I am confident that their migratory movements are usually performed at such times, having seen them, as well as several other species, come down from a considerable height in the air, after sun-rise, for the purpose of resting and procuring food.

The flight of the Yellow-crowned Heron is rather slow, and less protracted than that of the Night Heron, which it however somewhat resembles. When in numbers, and surprised on their perches, they usually rise almost perpendicularly for thirty or forty yards, and then take a particular direction, leading them to some well-known place. Whenever I have started them from the nest, especially on the Florida Keys, they would sneak off on wing quite low, under cover of the mangroves, and fly in this manner until they had performed the circuit of the island, when they would alight close to me, as if to see whether I had taken their eggs or young.

When on the ground, they exhibit little of the elegance displayed by the Louisiana, the Reddish, the Blue, or the White Herons; they advance with a less sedate pace, and seldom extend their neck much even when about to seize their food, which they appear to do with little concern, picking it up from the ground in the manner of a domestic fowl. Nor are they at all delicate in the choice of their viands, but swallow snails, fish, small snakes, crabs, crays, lizards, and leeches, as well as small quadrupeds, and young birds that have fallen from their nests. One which was killed by my friend EDWARD HARRIS, Esq., on the 19th of April, 1837, on an island in the Bay of Terre Blanche, about 4 o\\\'clock in the evening, was, when opened next morning, found to have swallowed a terrapin, measuring about an inch and a half in length, by one in breadth. It was still alive, and greatly surprised my companions as well as myself by crawling about when liberated.

This species places its nest either high or low, according to the nature of the place selected for it, and the abundance of food in the neighbourhood. In the interior of swampy woods, in Lower Louisiana, I have found the nests placed on the tops of the loftiest cypresses, and on low bushes, but seldom so close together as those of many other Herons. On the Florida Keys, where I have examined more of these tenements than in any other part, I found them either on the tops of mangroves, which there seldom attain a greater height than twenty-five feet, or on their lowest branches, and not more than two or three feet from the water. In the Carolinas, they usually resort to swamps, nestling on the bushes along their margins. The nest is similar to that of other Herons, being formed of dry sticks loosely put together, and a few weeds, with at times a scanty lining of fibrous roots. The eggs are generally three, never, in as far as I have seen, more, of a pale blue colour, inclining to green, thin-shelled, and averaging two inches in length by an inch and three and a half eighths in their greatest breadth. The young seldom remain in the nest until able to fly, as is the case with those of some other species, but usually leave it to follow their parents along the shores. If seared from the nest, they scramble along the branches with considerable agility, and hide whenever an opportunity occurs. I have given the figure of a young bird procured in October.

The differences between the periods at which this bird breeds in different latitudes, correspond with those observed with respect to other species of the same tribe. Thus, eggs and young may be procured on the Florida Keys six weeks sooner than in South Carolina, although two broods are usually raised in both districts, the birds frequently removing from one place to another for the purpose. The beautiful slender plumes on the head and back generally fall off soon after incubation commences, although I have on a few occasions found the male still bearing these ornaments when the female was sitting on her second set of eggs. When the young are just able to fly I have found them good eating, but the old birds I never relished.

When wounded, the Yellow-crowned Heron defends itself vigorously with its claws, the scratches inflicted by which are severe, and also strikes with the bill. If not brought to the ground, in a place where the trees are close and thickly branched, it is difficult to obtain them without a second shot, for they scamper quickly from one twig to another, and are very soon out of reach.

WILSON complains that the name \\\"Yellow-crowned\\\" should be given to this species, and this would almost induce me to suppose that be had never seen one in the breeding season, when the white of the head is strongly tinged with yellow, which however disappears at the approach of autumn, when the bird might with all propriety be named the White-crowned Heron.

The adult bird represented in the plate was shot by my friend Dr. BACHMAN, a few miles from Charleston, while I was in his company; and the drawing of the plant was made by his amiable sister-in-law, Miss MARTIN.

The upper mandible is slightly concave, with a median prominent ridge: the palate convex, with two ridges; the posterior aperture of the nares linear, with an oblique papillate flap on each side; the lower mandible deeply concave. The tongue is of moderate length, measuring 1 3/4 inches, emarginate at the base, trigonal, flat above, tapering to a point. The oesophagus, which is 12 inches long, gradually diminishes in diameter from 1 1/2 inches to 1 inch.
