39. LESSER WHITETHROAT. _Sylvia curruca_, Linnaeus. French, "Bee-fin babillard."--Like the Whitethroat, the Lesser Whitethroat is a regular, but by no means a numerous summer visitant to Guernsey. I saw a few in the willow-hedges about the Grand Mare, and in one or two other places near there, and young Le Cheminant had one or two eggs in his collection, probably taken about L'Eree. The Lesser Whitethroat is included in Professor Ansted's list, and only marked as occurring in Guernsey. There is at present no specimen in the Museum. 40. BLACKCAP. _Sylvia atricapilla_, Linnaeus. French, "Fauvette à tête noire," "Bec-fin à tête noire."--Though generally known as the Guernsey Nightingale, the Blackcap, though a regular, is by no means a numerous summer visitant. I have, however, always seen a few about every time I have been in the Island in the summer. There are a few eggs in the Museum, and in Le Cheminant's collection. The Blackcap is mentioned by Professor Ansted in his list, and restricted to Guernsey. There is only one specimen--a female--at present in the Museum. 41. WILLOW WREN. _Phylloscopus trochilus_, Linnaeus. French, "Bee-fin Pouillat."--The Willow Wren is a tolerably numerous summer visitant, I believe, to all the Islands, though I have only seen it myself in Guernsey and Sark. In Guernsey I have seen it about the Grand Mare, and in some trees near the road about St. George, and about the Vallon on the other side of the Island. It remains all the summer and breeds. Professor Ansted has not included it in his list, although it seems tolerably well known, and has a local name "D'mouâiselle," which Mr. Métivier, in his 'Dictionary,' applies to the Willow Wren of the English. This name, however, is probably equally applicable to the Chiffchaff. 42. CHIFFCHAFF. _Phylloscopus collybita_, Vieillot. French, "Bee-fin veloce."--The Chiffchaff is certainly more common in Guernsey than the Willow Wren. In Guernsey I have seen it in several places; about Candie, where a pair had a nest this summer in the mowing-grass before the house; near the Vallon; and about St. George. I have also seen it in Sark, but not in either of the other Islands, though no doubt it occurs in Herm, if not in Alderney. It is mentioned by Professor Ansted as occurring in Guernsey and Sark. I have never seen the Wood Wren in Guernsey, and, judging from its favourite habitations here in Somerset, I should not think it at all likely to remain in the Channel Islands through the summer, though an occasional straggler may touch the Islands on migration. There is no specimen of either the Chiffchaff or Willow Wren in the Museum.
