The Night Heron is said to be not uncommon on the shores of the Baltic, in the wide marshes of Bretagne and Lorraine, and on the banks of the Rhone. It passes the day concealed among the thick foliage of trees and shrubs, and feeds only by night. It builds its nest in trees, and lays four or five eggs.
THE COMMON BITTERN
BOTAURUS STELLÁRIS
Moustaches and crown black; upper plumage yellowish rust-red, spotted with dusky; the feathers of the neck elongated, marked with brown zigzag lines; primaries barred with rust-red and dusky grey; plumage beneath paler, marked with oblong dusky streaks; upper mandible brown, edged with yellow; lower, orbits, and feet, greenish yellow; irides bright yellow. Length two feet four inches. Eggs dingy green.
Macgillivray, who was as well acquainted as most ornithologists with birds haunting moors and swamps, admits that he never heard one, and thinks that a brother naturalist, who describes what, no doubt, he heard, mistook for the booming of the Bittern the drumming of a Snipe. Lord Lilford tells us that a lady of his acquaintance told him that as a young wife, living near marshes, she often was kept awake by the booming of Bitterns.
In Sir Thomas Browne's time, It was common In Norfolk, and was esteemed a better dish than the Heron.
Willughby, who wrote about the same time, 1676, says: 'The Bittern, or Mire-drum, it is said, makes either three or five boomings at a time—always an uneven number. It begins to bellow early in February, and continues during the breeding season. The common people believe that it thrusts its beak into a reed, and by the help of this makes its booming. Others maintain that it imitates the lowing of an ox by thrusting its beak into water, mud, or earth. They conceal themselves among rushes and reeds, and not unfrequently in hedges, with the head and neck erect. In autumn, after sunset, they are in the habit of rising into the air with a spiral ascent, so high that they are lost sight of. Meanwhile they utter a singular note, but not at all resembling the characteristic 'booming'.
It is called Botaurus, because it imitates boatum tauri, the bellowing of a bull. Of 'Botaurus', the names 'Bitour' and Bittern are evident corruptions; and the following names, in different languages, are all descriptive of the same peculiar note: Butor, Rordump, Myredromble, Trombone, Rohrtrummel, Rohrdommel, and Rordrum.
Of late years, so unusual has the occurrence become of Bitterns breeding in this country, owing to collectors, that the discovery of an egg in Norfolk has been thought worthy of being recorded in the transactions of the Linnean Society; and even the appearance of a bird at any season finds its way into the provincial newspapers or the magazines devoted to natural history: Stuffed specimens are, however, to be seen in most collections, where its form and plumage may be studied, though its habits can only be learnt, at least in England, from the accounts furnished by naturalists of a past generation. It comes now only to be shot.
The Bittern is a bird of wide geographical range, as it resorts, more or less, to all countries of Europe and Asia. Specimens are said to differ much in size, some being as large as the Heron, others considerably less; but there is no reason to suppose that they are of different species, a similar variation having been observed in other birds, as in the Curlew, for example, of which I have had in my possession at once four or five specimens all of different dimensions.
