Alaudidæ.—Spring: A spring rush is reported at Bell Rock between Feb. 5th and 25th; or possibly this may only belong to migration of 1880. Great numbers of Larks mixed with Rose Linnets, Starlings, and other species, from 2 to 5 a.m.; great numbers struck; wind on arrival light S.W., on departure fresh N.E., fog and rain. Feb. 18th, great numbers, all Larks, greatly exhausted, seen asleep, and others struck, but none found dead; wind light E.S.E., haze. On 19th, "small birds, not recognised, flew about for an hour, and left at dawn"; and on 25th great numbers, all Larks, much exhausted, at 1.30 a.m.; left after an hour's rest at dawn, flying N.W.—Autumn: Sumburgh Head, Pentland Skerries, Bell Rock, and Isle of May (numerous). Earliest at Sumburgh Head, Sept. 15th (breeds here, but left to-day); latest at Isle of May, Dec. 1st (two seen). Rushes at Isle of May, Sept. 24th; numbers on 25th and 26th, increased up to 27th; also at Pentland Skerries (accompanying Wheatears); also fewer on Sept. 15th, 16th, and 18th. Rush at Pentland Skerries, striking all night, Oct. 26th; stragglers on 1st and 8th.—Weather: Fresh S. wind Sept. 1st to 8th, to fresh S.E. and clear on 26th. Nov. 24th, at Sumburgh Head (along with Grey Linnets), fresh S., cloudy; and Dec. 1st, at Isle of May, two seen, as above recorded.
