The Natural History of Selborne, 1879/Letter 25
LETTER XXV.
Dear Sir, It gives me satisfaction to find that my account of the ousel migration pleases you. You put a very shrewd question when you ask me how I know that their autumnal migration is southward? Was not candour and openness the very life of natural history, I should pass over this query just as a sly commentator does over a crabbed passage in a classic; but common ingenuousness obliges me to confess, not without some degree of shame, that I only reasoned in that case from analogy. For as all other autumnal birds migrate from the northward to us, to partake of our milder winters, and return to the northward again when the rigorous cold abates, so I concluded that the ring-ousels did the same, as well as their congeners the fieldfares; and especially as ring-ousels are known to haunt cold mountainous countries: but I have good reason to suspect since that they may come to us from the westward; because I hear from very good authority, that they breed on Dartmoor; and that they forsake that wild district about the time that our visitors appear, and do not return till late in the spring.
I have taken a great deal of pains about your salicaria and mine, with a white stroke over its eye and a tawny rump.[e1] I have surveyed it alive and dead, and have procured several specimens, and am perfectly persuaded myself (and trust you will soon become convinced of the same) that it is no more nor less than the passer arundinaceus minor of Ray. This bird, by some means or other, seems to be entirely omitted in the British Zoology; and one reason probably was because it is so strangely classed in Ray, who ranges it among his picis affines. It ought no doubt to have gone among his aviculæ caudâ unicolore, and among your slender-billed small birds of the same division. Linnæus might with great propriety have put it into his genus of motacilla; and motacilla salicaria of his fauna suecica seems to come the nearest to it. It is no uncommon bird, haunting the sides of ponds and rivers where there is covert, and the reeds and sedges of moors. The country people in some places call it the sedge-bird. It sings incessantly night and day during the breeding-time, imitating the note of a sparrow, a swallow, a skylark; and has a strange hurrying manner in its song. My specimens correspond most minutely to the description of your fen salicaria shot near Revesby. Mr. Ray has given an excellent characteristic of it when he says, "Rostrum et pedes in hâc aviculâ multò majores sunt quâm pro corporis ratione." See letter, May 29th, 1769. (Preceding letter, xxiv.)
I have got you the egg of an œdicnemus, or stone-curlew, which was picked up in a fallow on the naked ground; there were two, but the finder inadvertently crushed one with his foot before he saw them.
When I wrote to you last year on reptiles, I wish I had not forgot to mention the faculty that snakes have of stinking se defendendo. I knew a gentleman who kept a tame snake, which was in its person as sweet as any animal while in good humour and unalarmed; but as soon as a stranger, or a dog or cat, came in, it fell to hissing, and filled the room with such nauseous effluvia as rendered it hardly supportable. Thus the squnck, or stonck, of Ray's "Synop. Quadr." is an innocuous and sweet animal; but, when pressed hard by dogs and men, it can eject such a most pestilent and fetid smell and excrement, that nothing can be more horrible.
A gentleman sent me lately a fine specimen of the lanius minor cinerascens cum maculâ in scapulis albâ, Raii; which is a bird that, at the time of your publishing your two first volumes of "British Zoology," I find you had not seen. You have described it well from Edwards's drawing.
note to letter xxiv.
e1 ↑ The bird referred to is the sedge-warbler. White says it sings like a reed-sparrow. The reed-sparrow has no song, but the reed-wren or reed-warbler has, and White must mean this species by the term reed-sparrow.
