Motacillidæ.--Spring: Bell Rock and Isle of May (only two). Wagtails. Earliest at Isle of May, March 12th; latest at Bell Rock, April 13th. General Remarks:--The latter "running over the rocks, but leaving at high tide, as all birds do that land upon these rocks" (J. Agnew).--Autumn: Pentland Skerries and Isle of May (three records). Wagtails. Earliest at Pentland Skerries (three all day), when a gale from N., Aug. 27th; latest at Isle of May, Sept. 24th, "when a few new-comers, having more white upon them than the few residents, appeared." Also occurred at Pentland Skerries, Sept. 10th. Pipits at Whalsey Skerries, Pentland Skerries, and Isle of May (few records). Earliest at Whalsey Skerries, Aug. 28th (following Sparrowhawk), but all left next day; latest at Pentland Skerries, Oct. 25th (six struck at night). Rush (on small scale) at Isle of May, Sept. 24th, 25th, and 26th. General Notes:--Mr. Agnew speaks of some being always here, but additions on Sept. 24th. Possibly Mr. Agnew alludes, however, to Rock Pipits as the residents. The Meadow Pipit is probably the species first seen as additions on Sept. 24th. N.B. The Rock Pipit is a larger bird than the Meadow Pipit; please shoot one of the "resident birds" and then one of the "additions," and if carefully compared, I think Mr. Agnew will detect the difference. 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 Turdidæ, supra) part of a general rush of migrants.
