Whilst on the subject of Cuckoos I may mention, for the information of such of my Guernsey readers who are not ornithologists, and therefore not well acquainted with the fact, the peculiar state of plumage in which the female Cuckoo occasionally returns northward in her second summer; I mean the dull reddish plumage barred with brown, extremely like that of the female Kestrel: in this plumage she occasionally returns in her second year and breeds; but when this is changed for the more general plumage I am unable to state for certain, but probably after the second autumnal moult. The changes of plumage in the Cuckoo, however, appear to be rather irregular, as I have one killed in June nearly in the normal plumage, but with many of the old feathers left, which have a very Kestrel-like appearance, being redder than the ordinary plumage of the young bird; some of the tail-feathers, however, have more the appearance of the ordinary tail-feathers of the young Cuckoo soon after the tail has reached its full growth: the moult in this bird must have been very irregular, as it was not completed in June, when, as a rule, it would have been in full plumage, unless, as may possibly be the case, this bird was the produce of a second laying during the southern migration, and consequently, instead of a year, be only about six months old. This, however, is not a very common state of plumage; but it is by no means uncommon to find a Cuckoo in May or June with a good deal of rusty reddish barred with brown, forming a sort of collar on the breast. I merely mention these rather abnormal changes of plumage, as they may be interesting to any of my Guernsey readers into whose hands a Cuckoo may fall in a state of change and prove a puzzle as to its identity. The Cuckoo departs from the Channel Islands much about the same time that it does from England on its southern migration in August or September. Occasionally, however, this southern migration during the winter seems to be doubted, as a clerical friend of mine once told me that a brother clergyman, a well educated and even a learned man, told him, when talking about Cuckoos and what became of them in winter, that "it was a mistake to suppose they migrated, but that they all turned into Sparrow-hawks in the winter." As my friend said, could any one believe this of a well-educated man in the nineteenth century?
The Cuckoo is mentioned in Professor Ansted's list, but only marked as occurring in Guernsey and Sark. There are three specimens, one adult and two young, in the Museum, as well as some very ordinary eggs.
85. KINGFISHER. Alcedo ispida, Linnaeus. French, "Martin Pecheur."—The Kingfisher is by no means uncommon, is generally spread over the Islands, and is resident and breeds at all events in Guernsey, if not in the other Islands also. It is generally to be seen amongst the wild rocks which surround L'Ancresse Common, where it feeds on the small fish left in the clear pools formed amongst the rocks by the receding tide; it is also by no means uncommon amongst the more sheltered bays in the high rocky part of the Island; it is also to be found about the small ponds in various gardens. About those in Candie Garden I have frequently seen Kingfishers, and they breed about the large ponds in the Vale in Mr. De Putron's grounds; they also occasionally visit the wild rocky islets to the northward of Herm, even as far as the Amfrocques, the farthest out of the lot. As well as about the Vale ponds, the Kingfisher breeds in holes in the rocks all round the Island. I have not myself seen it in Alderney, but Captain Hubbach writes me word he saw one there about Christmas, 1862. I think its numbers are slightly increased in the autumn by migrants, as I have certainly seen more specimens in Mr. Couch's shop at that time of year than at any other; this may perhaps, however, be accounted for, at all events partially, by its being protected by the Sea Bird Act during the summer and in early autumn, where the 'Martin pêcheur' appears as one of the "Oiseaux de Mer."
It is included in Professor Ansted's list, and only marked as occurring in Guernsey and Sark. There are three specimens now in the Museum.
86. NIGHTJAR. Caprimulgus enropaeus, Linnaeus. French, "Engoulevent ordinaire."—The Nightjar is a regular autumnal visitant, a few perhaps arriving in the spring and remaining to breed, but by far the greater number only making their appearance on their southward migration in the autumn. The Nightjar occasionally remains very late in the Islands, as Miss Carey records one in the 'Zoologist' for 1872 as occurring on the 16th of October; and I have one killed as late as the 12th of November: this bird had its stomach crammed with black beetles, not our common domestic nuisances, but small winged black beetles: these dates are later than the Nightjar usually remains in England, though Yarrell notices one in Devon as late as the 6th of November, and one in Cornwall on the 27th of November. Colonel Irby, on the faith of Fabier, says the Nightjars cross the Straits of Gibraltar on their southward journey from September to November; so these late stayers in Cornwall and Guernsey have not much time to complete their journey if they intend going as far south as the coast of Africa; perhaps, however the Guernsey ones have no such intention, as Mr. Gallienne, in his remarks published with Professor Ansted's list, says "The Nightjar breeds here, and I have obtained it summer and winter." Mr. MacCulloch tells me the Goatsucker is looked upon by the Guernsey people as a bird of ill-omen and a companion of witches in their aërial rambles. The bird-stuffer in Alderney had some wings of Nightjars nailed up behind his door which had been shot in that Island by himself.
Professor Ansted includes the Nightjar in his list, but only marks it as occurring in Guernsey and Sark. There are two specimens, a male and female, in the Museum, but no date as to time of their occurrence.
87. SWIFT. Cypselus apus, Linnaeus. French, "Martinet de Muraille."—The Swift is a tolerably numerous summer visitant to all the Islands, but I think most numerous in Sark, where hundreds of these birds may be seen flying about the Coupée, amongst the rocks of which place and Little Sark they breed in considerable numbers. Mr. MacCulloch and Mr. Gallienne appear to think the Swift rare in Guernsey, as Mr Gallienne says in his remarks on Professor Ansted's list, "The swift appears here (Guernsey) in very small numbers, but is abundant in Sark;" and Mr. MacCulloch writes me word, "I consider the Swift very rare in Guernsey." I certainly cannot quite agree with this, as I have found them by no means uncommon, though certainly rather locally distributed in Guernsey. One afternoon this summer (1878) Mr. Howard Saunders and I counted forty within sight at one time about the Gull Cliff, near the old deserted house now known as Victor Hugo's house, as he has immortalised it by describing it in his 'Travailleurs de la Mer.' The Swifts use this and two similar houses not very far off for breeding purposes, a good many nesting in them, and others, as in Sark, amongst the cliffs. Young Le Cheminant had a few Swifts' eggs in his small collection, probably taken from this very house, as the Swift is certainly, as Mr. MacCulloch says, rare in other parts of Guernsey. In Alderney the Swift is tolerably common, and a good many pairs were breeding about Scott's Hotel when I was there this year (1878). Probably a good many Swifts visit the Islands, especially Alderney, for a short time on migration, principally in the autumn, as once when I was crossing from Weymouth to Guernsey, on the 18th of August, I saw a large flock of Swifts just starting on their migratory flight; they were plodding steadily on against a stormy southerly breeze, spread out like a line of skirmishers, not very high, but at a good distance apart; there was none of the wild dashing about and screeching which one usually connects with the flight of the Swift, but a steady business-like flight; they went a little to the eastward of our course in the steamer, and this would have brought them to land in Alderney or Cape la Hague.
Professor Ansted included the Swift in his list, but oddly enough, considering the remark of Mr. Gallienne above quoted, marks it as only occurring in Guernsey. There is no specimen at present in the Museum.
88. SWALLOW, Hirundo rustica, Linnaeus. French, "Hirondelle de Cheminée."—According to Métivier's 'Dictionary,' "Aronde" is the local Guernsey-French name of the Swallow, which is a common summer visitant to all the Islands, and very generally distributed over the whole of them, and not having particular favourite habitations as the Martin has. It arrives and departs much about the same time that it does in England, except that I do not remember ever to have seen any laggers quite so late as some of those in England. A few migratory flocks probably rest for a short time in the Islands before continuing their journey north or south, as the case may be; the earliest arrivals and the latest laggers belong to such migratory flocks, the regular summer residents probably not arriving quite so soon, and departing a little before those that pay a passing visit; consequently the number of residents does not appear at any time to be materially increased by such wandering flocks.
Professor Ansted includes the Swallow in his list, but only marks it as occurring in Guernsey and Sark. There is no specimen of any of the Hirundines in the Museum.
