August 4th, 1767.

It has been my misfortune never to have had any neighbours whose studies have led them towards the pursuit of natural knowledge; so that, for want of a companion to quicken my industry and sharpen my attention, I have made but slender progress in a kind of information to which I have been attached from my childhood.

As to swallows (hirundines rusticæ) being found in a torpid state during the winter in the Isle of Wight or any part of this country, I never heard any such account worth attending to. But a clergyman, of an inquisitive turn, assures me, that when he was a great boy, some workmen, in pulling down the battlements of a church tower early in the spring, found two or three swifts (hirundines apodes) among the rubbish, which were at first appearance dead, but on being carried towards the fire revived. He told me, that out of his great care to preserve them, he put them in a paper bag, and hung them by the kitchen fire, where they were suffocated.

Another intelligent person has informed me, that while he was a schoolboy at Brighthelmstone, in Sussex, a great fragment of the chalk cliff fell down one stormy winter on the beach, and that many people found swallows among the rubbish; but on my questioning him whether he saw any of those birds himself, to my no small disappointment, he answered me in the negative; but that others assured him they did.

Young broods of swallows began to appear this year on July 11th, and young martins (hirundines urbicæ) were then fledged in their nests. Both species will breed again once. For I see by my fauna of last year, that young broods came forth so late as September 18th. Are not these late hatchings more in favour of hiding than migration? Nay, some young martins remained in their nests last year so late as September 29th; and yet they totally disappeared with us by the 5th October.

How strange it is that the swift, which seems to live exactly the same life with the swallow and house-martin, should leave us before the middle of August invariably! while the latter stay often till the middle of October; and once I saw numbers of house-martins on the 7th November. The martins and red-wing fieldfares were flying in sight together, an uncommon assemblage of summer and winter birds!

A little yellow bird (it is either a species of the alauda trivialis, or rather perhaps of the motacilla trochilus) still continues to make a sibilous shivering noise in the tops of tall woods. The stoparola of Ray (for which we have as yet no name in these parts) is called in your zoology the fly-catcher. There is one circumstance characteristic of this bird which seems to have escaped observation, and that is, it takes its stand on the top of some stake or post, from whence it springs forth on its prey, catching a fly in the air, and hardly ever touching the ground, but returning still to the same stand for many times together.

I perceive there are more than one species of the motacilla trochilus. Mr. Derham supposes, in “Ray’s Philos. Letters,” that he has discovered three. In these there is again an instance of some very common birds that have as yet no English name.

Mr. Stillingfleet makes a question whether the blackcap (motacilla atricapilla) be a bird of passage or not: I think there is no doubt of it: for, in April, in the first fine weather, they come trooping, all at once, into these parts, but are never seen in the winter. They are delicate songsters.

Numbers of snipes breed every summer in some moory ground on the verge of this parish. It is very amusing to see the cock bird on wing at that time, and to hear his piping and humming notes.

I have had no opportunity yet of procuring any of those mice which I mentioned to you in town. The person that brought me the last says they are plenty in harvest, at which time I will take care to get more; and will endeavour to put the matter out of doubt whether it be a nondescript species or not.

I suspect much there may be two species of water-rats. Ray says, and Linnæus after him, that the water-rat is web-footed behind. Now I have discovered a rat on the banks of our little stream that is not web-footed, and yet is an excellent swimmer and diver: it answers exactly to the mus amphibius of Linnæus (see Syst. Nat.), which he says “natat in fossis et urinatur.” I should be glad to procure one “plantis palmatis.” Linnæus seems to be in a puzzle about his mus amphibius, and to doubt whether it differs from his mus terrestris; which if it be, as he allows, the “mus agrestis capite grandi brachyuros,” of Ray, is widely different from the water-rat, both in size, make, and manner of life.

As to the falco, which I mentioned in town, I shall take the liberty to send it down to you into Wales; presuming on your candour that you will excuse me if it should appear as familiar to you as it is strange to me. Though mutilated “qualem dices … ante hac fuisse tales cum sint reliquiæ!”

It haunted a marshy piece of ground in quest of wild-ducks and snipes; but, when it was shot, had just knocked down a rook, which it was tearing in pieces. I cannot make it answer to any of our English hawks; neither could I find any like it at the curious exhibition of stuffed birds in Spring Gardens. I found it nailed up at the end of a barn, which is the countryman’s museum.

The parish I live in is a very abrupt, uneven country, full of hills and woods, and therefore full of birds.
