The words "Sand Larks," and "Sea Larks," so vague, and signifying almost any of the smaller Sandpipers, is now better understood by the production of legs and wings--those of the Curlew Sandpiper, Purple Sandpiper, Common Sandpiper, and Turnstone having been sent. A leg and wing of the Fork-tailed Petrel was forwarded from Eagle Island, W., off Mayo, caught at lantern in second week of October. An egg of this species is recorded to have been found on the Tearaght, Co. Kerry (_Zoologist_, 1886, p. 367). Most of the legs and wings were obtained at the autumnal migration. The autumn rush of Thrushes, Starlings, Blackbirds, and Larks took place October 20th to 28th, on the E. and S.E. coasts, there being little evidence of it on the W. coast. From 27th February to 1st March another great movement took place on the S.E. coast, and again about March 27th. At the N.W. stations a great rush of Fieldfares, Blackbirds, Thrushes, and Starlings occurred December 17th and 24th, under the influence of a sudden pinch of cold. The Fieldfares were noticed in great numbers at Innishtrahull, a rocky islet six miles north of Donegal. Mr M. S. Kennedy "never saw the like." There was snow, with a very strong wind. At Rathlin O'Birne (West Donegal) immense flocks of birds--Starlings, Thrushes, and Fieldfares--passed west December 18th to 23d. The nearest land to the west of this rocky island is America, and one is puzzled to know where the birds were going; but this is not an isolated occurrence--the westerly flight of land birds at stations off the west coast of Ireland has been noticed on other occasions. The movement is apparently as reckless as that of the Lemmings. The Ring Ouzel is again stated to have been seen in the winter (January 15th) at Mine Head. It is strange that not a single leg and wing of the Grey Linnet, or the Twite (birds, doubtless, included under the name of "Linnets"), has yet been received. They seem rarely to strike. There are two or three instances of the Golden Plover having been killed striking in 1886. The "Cream-coloured" Gulls seen off Blackrock, Mayo, November 5th, and also seen in August 1881, April and May 1882, and October 11th, 1884 (see Report, 1884, p. 181), were probably Iceland Gulls. The Gannet is well known to every light-keeper, and its movements are not likely to be confounded with any other bird. The entries, therefore, under it may be examined with confidence. Species which are ill-defined, or named with doubtful accuracy in the Report, are put in in inverted commas. In Ireland birds are far less numerous than in Great Britain, and their movements are less distinctly marked. Few entries have, therefore, been omitted, for their value cannot be estimated until a number of Reports have been compared. It is proposed next year to analyse all the Irish observations.
