131. BITTERN. _Botaurus stellaris_, Linnaeus. French, "Heron grand butor," "Le grand butor."--Bitterns were probably at one time more common in Guernsey than they are at present, drainage and better cultivation having contributed to thin their numbers, as it has done in England; and Mr. MacCulloch tells me that in his youth they were by no means uncommon. Of late years, however, they have become much more uncommon, though, as he adds, specimens have been shot within the last three or four years. They seem now, however, to be confined to occasional autumnal and winter visitants. Mr. Couch says ('Zoologist' for 1871):--"On the 30th December, 1874, after a heavy fall of snow, I had a female Bittern brought to me to be stuffed, shot in the morning in the Marais; and on the 2nd of January following another was shot on the beach near the Vale Church. I had also part of some of the quill-feathers of a Bittern sent to me for identification by Mrs. Jago, which had been killed in the Islands the last week in January, 1879." These are the most recent specimens I have been able to get any account of. The bird-stuffer in Alderney (Mr. Grieve) and his friend told me they had shot Bitterns in that island, but did not remember the date. The Bittern is included in Professor Ansted's list, but only marked as occurring in Guernsey. There is no specimen in the Museum. 132. AMERICAN BITTERN. _Botaurus lentiginosus_, Montagu. French, "Heron lentigineux."[21]--This occasional straggler from the New World has once, in its wanderings, reached the Channel Islands, and was shot in Guernsey on the 27th October, 1870, and was duly recorded by me in the 'Zoologist' for 1871; it is now in my collection. This is the only occurrence of this bird in the Channel Islands yet recorded; but as the bird occasionally crosses to this side of the Atlantic--several specimens having occurred in the British Islands--it may possibly occur in Guernsey or some of the Channel Islands again. It may, therefore, be as well to point out the principal distinctions between this bird and the Common Bittern last mentioned. Between the adult birds there can be no mistake: the longer and looser feathers on the fore part of the neck, which are slightly streaked and freckled with dark brown, may be immediately distinguished from the much shorter and more regularly marked feathers on the neck of the adult American Bittern. This distinction, however, is not perfectly clear in young birds; but, at any age or in any state of plumage, the birds may be immediately distinguished by the primary quill-feathers, which in the American Bittern are a uniform dark chocolate-brown without any marks whatever, while in the Common Bittern they are much marked and streaked with pale yellowish brown; this may be always relied on at any age or in any plumage.
