Hirundinidæ.—Spring: Cromarty, Auskerry, Sumburgh Head, and Whalsey Skerries. First arrivals at Auskerry, May 1st (Martins and Swallows remained three days and then left); latest, at Whalsey Skerries, June 27th (a few flying about). Rush hardly perceptible. General Notes:—At Sumburgh Head four pairs all summer; all disappeared on night of July 20th. That night one pair slept on the staircase-window.—Autumn: Whalsey Skerries, Sumburgh Head, Auskerry, Pentland Skerries, Cromarty, and Isle of May (a number). Earliest (see remarks under Spring Migration, supra, July 20th); latest at Sumburgh Head, Oct. 1st (one seen). No great rush appreciable, but flocks of Swallows and Martins seen at Auskerry Aug. 1st and 4th, and on 1st at Isle of May (one found dead previous night after heavy gales); (see Notes under ssss1, supra) part of a general rush of migrants.

Fringillidæ.—Spring: Isle of May, Bell Rock, Sumburgh Head (considerable movement). Linnets. Earliest at Isle of May, March 4th (asleep all night on doorway): two green Linnets. Latest at Isle of May, April 14th (seen). General Notes:—Two days previous "considerable number of Chaffinches, which are very unusual at this season; also one Bullfinch." From a remark of Mr. Agnew, that some of the latter breed on Isle of May, I suspect these "Linnets" will prove to be Twites or Mountain Linnets, Linota flavirostris ? These Linnets are also noted at Bell Rock on April 10th, and at Sumburgh Head on March 7th.—Autumn: Sumburgh Head, Isle of May, and Inch Keith (large movement). Earliest (Grey Linnets) at Isle of May, Aug. 18th (mostly young, apparently in broods, in large numbers); latest at Sumburgh Head, Jan. 14th, 1882 (three seen). Rushes (Chaffinches) at Isle of May, Sept. 22nd to 26th (see Notes under Turdidæ). Brambling also on 24th (one sent me for identification). Siskin at Inch Keith, Sept. 25th. [General Notes:—A desultory migration, kept up of Linnets and Siskins (which are rare on the Isle of May), occurred Oct. 4th and 5th. A Redpole on 8th, at Sumburgh Head.] A rush between Oct. 20th and 27th at Isle of May, during which time Redpoles (20th and 24th), Chaffinches (22nd), Bramblings (21st), one Siskin (27th), and Grey Linnets or Twites (24th), at Sumburgh Head; about fifty, along with ten Larks (see ssss1.). Occasional birds seen at Isle of May:—Nov. 12th, one Siskin; 28th, one hen Linnet; and on Nov. 21st, at Inch Keith, one Siskin. On Dec. 3rd, at Isle of May, one Redpole, preserved in spirits (vide infra), and one Brambling, same time and place. On the 4th, Green Linnets at Sumburgh Head, and in Jan., 1882 (latest), three Green Linnets on 14th. In Shetland prevailing winds during the winter were from S.W., "and consequently no strange birds visited us." A flock of Mealy Redpoles arrived at Lerwick, and took up their abode for a time in Mr. P. T. Garrick's garden, at Prospect House. This movement doubtless belongs to the Spring Migration of 1882. In August unusually large flocks of Greenfinches were observed by Mr. Service near Dumfries; left after two weeks, and reappeared in January, 1882.
