usually occurs in the autumn, and, as a rule, has a very short lease of life after its arrival in the Islands, which is not to be wondered at, as it is considered, and no doubt is, mischievous both to sheep and poultry; and in so thickly populated a country, where every one carries a gun, a large bird like the White-tailed Eagle can hardly escape notice and consequent destruction for any length of time. It might, however, if unmolested, occasionally remain throughout the winter, and probably sometimes wanders to the Islands at that time, as Mr. Harvie Brown records ('Zoologist' for 1869, p. 1591) one as having been killed, poisoned by strychnine, in Herm in the month of January. This was, no doubt, a late winter visitant, as it is hardly possible that the bird can have escaped for so long a time, as it would have done had it visited the Islands at its usual time, October or November. All the Channel Island specimens of the White-tailed Eagle which I have seen have been young birds of the first or second year, in the immature plumage in which the bird is known as the Sea Eagle of Bewick, and in which it is occasionally mistaken for the Golden Eagle, which bird has never, I believe, occurred in the Islands. Of course in the adult plumage, when this bird has its white tail and head, no such mistake could occur, but in the immature plumage in which the bird usually makes its appearance such a mistake does occasionally happen, and afterwards it becomes difficult to convince the owner that he has not a Golden Eagle; in fact he usually feels rather insulted when told of his mistake, and ignores all suggestions of anything like an infallible test, so it may be as well to mention that the birds may be distinguished in any state of plumage and at any age by the tarsus, which in the White-tailed Eagle is bare of feathers and in the Golden Eagle is feathered to the junction of the toes. I have one in my possession shot at Bordeaux harbour on the 14th of November, 1871, and I saw one in the flesh at Mr. Couch's, the bird-stuffer, which had been shot at Alderney on the 2nd of November in the same year; and Mr. MacCulloch writes to me that one was wounded and taken alive in the parish of the Forest in Guernsey in 1845. It was said to be one of a pair, and he adds—"I have known several instances of its appearance since both here (Guernsey) and in Herm," but unluckily he gives no dates and could not remember at what time of year any of the occurrences he had noted had taken place. This is to be regretted, as although the bird occurs almost every autumn—indeed, so frequently as to render mention of further instances of its occurrence at that time of year unnecessary—its occurrence in the spring is rare, and some of those noted by Mr. MacCulloch might have been at that time of year. As it is, I only know of one spring occurrence, and that was reported to me by Mr. Couch as having taken place at Herm on the 23rd of March, 1877.

The White-tailed Eagle is included in Professor Ansted's list, but its range in the Islands is restricted to Guernsey. There is one in the museum, probably killed in Guernsey, in the plumage in which the Channel Island specimens usually occur, but no note is given as to locality or date.

2. OSPREY. Pandion halioeetus, Linnaeus. French, "Balbusard."—I have never met with the Osprey myself in the Channel Islands, nor have I, as far as I remember, seen a Channel Island specimen. I include it, however, on the authority of a note kindly sent to me by Mr. MacCulloch, who says:—"An Osprey was shot at St. Samsons, in Guernsey, on the 29th of October, 1868. I cannot, however, say whether at the time it was examined by a competent naturalist, and as both the Osprey and the White-tailed Eagle are fishers, a mistake may have been made in naming it." Of course such a mistake as suggested is possible, but as the Guernsey fishermen and gunners, especially the St. Samsons men, are well acquainted with the White-tailed Eagle, I should not think it probable that the mistake had been made. The bird, however, cannot be considered at all common in the Islands; there is no specimen in the Guernsey Museum, and Mr. Couch has never mentioned to me having had one through his hands, or recorded it in the 'Zoologist,' as he would have done had he had one; neither does Mrs. Jago (late Miss Cumber), who used to do a good deal of stuffing in Guernsey about thirty years ago, remember having had one through her hands. There can be no reason, however, why it should not occasionally occur in the Islands, as it does so both on the French and English side of the Channel. The wonder rather is that it is so rare as it appears to be.

The Osprey, however, is mentioned in Professor Ansted's list, and only marked as occurring in Guernsey.

3. GREENLAND FALCON. Falco candicans, Gmelin.—I was much surprised on my last visit to Alderney, on the 27th of June, 1878, on going into a small carpenter's shop in the town, whose owner, besides being a carpenter, is also an amateur bird-stuffer, though of the roughest description, to find, amongst the dust of his shop, not only the Purple Heron, which I went especially to see, and which is mentioned afterwards, but a young Greenland Falcon which he informed me had been shot in that island about eighteen months ago. This statement was afterwards confirmed by the person who shot the bird, who was sent for and came in whilst I was still in the shop. Unfortunately, neither the carpenter nor his friend who shot the bird had made any note of the date, and could only remember that the one had shot the bird in that Island about eighteen months ago and the other had stuffed it immediately after. This would bring it to the winter of 1876-77, or, more probably, the late autumn of 1876. In the course of conversation it appeared to me that the Snow Falcon—as they called this bird—was not entirely unknown to the carpenter or his friend, though neither could remember at the time another instance of one having been killed in that Island. It is, however, by no means improbable that either this species or the next mentioned, or both, may have occurred in the Islands before, as Professor Ansted, though he gives no date or locality, includes the Gyr Falcon in his list of Channel Island birds. As all three of the large northern white Falcons were at one time included under the name of Gyr Falcons, and, as Professor Ansted gives no description of the bird mentioned by him, it is impossible to say to which species he alluded. We may fairly conclude, however, that it was either the present species or the Iceland Falcon, as it could hardly have been the darker and less wandering species, the Norway Falcon, the true Gyr Falcon of falconers, Falco gyrfalco of Linnaeus, which does not wander so far from its native home, and has never yet, as far as is at present known, occurred in any part of the British Islands, and certainly not so far south as the Channel Islands. This latter, indeed, is an extremely southern latitude for either the Greenland or Iceland Falcon, the next being in Cornwall, from which county both species have been recorded by Mr. Rodd. Neither species, however, is recorded as having occurred in any of the neighbouring parts of France.

4. ICELAND FALCON. Falco islandus, Gmelin.—An Iceland Falcon was killed on the little Island of Herm on the 11th of April, 1876, where it had been seen about for some time, by the gamekeeper. It had another similar bird in company with it, and probably the pair were living very well upon the game-birds which had been imported and preserved in that island, as the keeper saw them kill more than one Pheasant before he shot this bird. The other fortunately escaped. The bird which was killed is now in my possession, and is a fully adult Iceland Falcon, and Mr. Couch, the bird-stuffer who skinned it, informed me a male by dissection. Though to a certain extent I have profited by it, so far as to have the only Channel Island example of the Iceland Falcon in my possession, I cannot help regretting that this
