Mr. Blake-Knox, a well-known naturalist, resident in the county of Dublin, says (“Zoologist,” 1866, p. 300), “I tried very hard this year to add the Wood Wren to our Dublin avifauna, and though I killed some dozens of snowy-white-bellied Willow Wrens, they were all the common _Sylvia trochilus_. That the bird is Irish I am sure, for I have heard it. Should an Irish ornithologist see this, will he try for it, if he should live in a wooded district, such as the counties Wicklow and Wexford? I am sure it is neglected for want of a certain distinction.” Since this note was published, the Wood Wren has actually been obtained in Ireland, a specimen having been shot in the county of Fermanagh by Sir Victor Brooke, and preserved by him in June, 1870. Another was obtained the same year at Glen Druid in the county of Dublin, as reported by Mr. Blake-Knox. Both Sir William Jardine and Macgillivray have referred to the Wood Warbler being found northward to the middle districts of Scotland, a circumstance which appears to have been overlooked by Mr. Yarrell, since he says (vol. i. p. 349, 3rd edit.), “I am not aware of any record of its appearance in Scotland.” This statement, however, has been rectified in the fourth edition of this standard work by Professor Newton, who remarks: “In Scotland it is known to breed regularly in the counties of Dumfries, Wigton, Lanark and Berwick, the Lothians and Perthshire, and occasionally in those of Roxburgh, Selkirk, Renfrew and Stirling.” Mr. A. G. More, in an article “On the Distribution of Birds in Great Britain during the Nesting Season,” published in the “Ibis” for 1865, observes (p. 26), that the Wood Warbler “in Scotland ranges further north than the Chiff-chaff, having been observed by the Duke of Argyle in Argyleshire and at Balmoral.” According to Mr. Robert Gray, of Glasgow, it has been observed in Inverness and Aberdeenshire, and Mr. Edwards has found it in Banffshire. Beyond the British Islands the Wood Warbler is found throughout Europe, though rare in the north, and it extends eastward to Siberia and southward to Algeria, Egypt and Abyssinia. It arrives in this country generally about the middle of April, and leaves again in September. [Illustration: WILLOW WARBLER] THE WILLOW WARBLER. (_Phylloscopus trochilus._) The Willow Warbler is much more generally distributed than the last-named bird; but it is possible that it is considered commoner from the difference in the haunts of the two species—the Wood Warbler, as already remarked, keeping further away from habitations. As a rule, the Willow Wren arrives in this country about the end of the first week in April—that is to say, before the Wood Warbler, but not so early as the Chiff-chaff, which is the first of the genus to appear.
