37. DARTFORD WARBLER. _Melizophilus undatus,_ Boddaert. French, "Pitchou Provencal," "Bee-fin Pittechou."--The Dartford Warbler is by no means common in the Channel Islands--indeed I have never seen one there myself, but Miss C.B. Carey records one in the 'Zoologist' for 1874 as having been knocked down with a stone in the April of that year and brought into Couch's shop, where she saw it. I have no doubt of the correctness of this identification, as Miss Carey knew the bird well. I see no reason why it should not be more common in Guernsey than is usually supposed, as there are many places well suited to it, but its rather dull plumage, and its habit of hiding itself in thick furze-bushes, and creeping from one to another as soon as disturbed, contribute to keep it much out of sight, unless one knows and can imitate its call-note, in which case the male bird will soon answer and flutter up to the topmost twig of the furze-bush in which it may have previously been concealed, fluttering its wings, and repeating the call until again disturbed. This is the only occurrence of which I am aware in any of the Islands, included in the limits I have prescribed for myself; but Mr. Harvie Brown has recorded two seen by him near Grève de Lecq, in Jersey, in January. See 'Zoologist' for 1869, p. 1561. It is not included in Professor Ansted's list, and there is no specimen in the Museum. 38. WHITETHROAT. _Sylvia rufa_, Boddaert. French, "Fauvette grise," "Bec-fin Grisette."--The Whitethroat has hitherto perhaps been better known by the name used in the former edition of 'Yarrell' and by Messrs. Degland and Gerbe, _Curruca cinerea_, but in consequence of the inexorable rule of the British Association the name "_rufa_," given by Boddaert in 1783, has now been accepted for this bird. I have not generally thought it necessary to point out these changes, but in this instance it seemed necessary to do so, as in the former edition of 'Yarrell' the Chiffchaff was called by the name _Sylvia rufa_, and this might possibly have caused some confusion unless the change had been pointed out. The Whitethroat is by no means so common in the Channel Islands as it is in England, and though a regular summer visitant it only makes its appearance in small numbers. A few, however, may be seen about the fields and hedgerows in the more cultivated parts of the country. It certainly has not got the reputation for mischief in the garden it has in England, as none of the gardeners I asked about it, and who were complaining grievously of the mischief done by birds, ever mentioned the Whitethroat, or knew the bird when asked about it. Professor Ansted includes the bird in his list, and restricts it to Guernsey, but I see no reason why it should not occur equally in Sark and Herm. There is no specimen at present in the Museum.
