Titmice.--The negative information that Mr. Edgar never saw any Titmice at the Butt of Lewis lighthouse is worthy of record. I have notes of their occurrence at M'Arthur's Head and Lamlash; in each case a single bird struck the lantern, Nov. 16th and Aug. 17th, at 6 p.m. and 10 a.m. respectively; both during west wind, and light air. Fieldfare.--Occurred at Monach Island and Douglas Head, and is reported as usually seen at Butt of Lewis, though not this year. At Monach Island a number struck, and fifteen were killed, between 8 p.m. and 4 a.m., on Oct. 21st and 22nd; wind S.W., fresh, and drizzling rain. At Douglas Head one was seen on Oct. 16th, at 10 a.m.; wind N., moderate breeze, and cloudy. Thrush.--The most northern station is, for 1879, Isle Ornsay. Mr. Edgar; however, adds the general information that in most years the Butt of Lewis yields large numbers at the lantern; thence southward at Skerryvore, Dhuheartach, Rhinns of Islay, Lochindaul, Lamlash, Corsewall, and Point of Ayre. The earliest date is Sept. 19th, when a mixed flock of Thrushes and Blackbirds passed in variable winds, and clear, at Lamlash. The latest date is Dec. 3rd, when "Thrushes" passed Lochindaul in the "daytime." But this may be due to local influences and hard frost then registered. The next latest date is Nov. 24th, when one was seen in the daytime, 2 p.m.; wind N.E., fresh, clear; this would give sixty-six days for the passage, or, taking the later date of Dec. 3rd, seventy-six days. The rushes were on Sep. 19th (_ut sup._); a "great rush" Oct. 21st to 28th. On Oct. 21st at Point of Ayr, two hundred "along with Blackbirds" seen at 1.80 p.m.; wind N. and N.W., strong, clear, with occasional showers. Also at the Rhinns of Islay, five seen, and so through records of Oct. 22nd, 18th to 28th, when three hundred "dark grey birds larger than a common Thrush!!?" (probably Missel Thrush, _Turdus viscivorus_) were seen at Point of Ayr; wind S.S.E., light, and hazy; and at Skerryvore about forty (of which ten killed) at 7 p.m.; wind S.E., light breeze, and haze. Thrushes travel with winds from S.E. to S.W. by preference, but also with winds from W. to N.E., through N.; observed most, as with most other species at lanterns, in hazy and rainy weather, but the great rush took place in "clear, with occasional showers," and "hazy and fine." Returns show that out of sixteen dates reported upon, only three show a diurnal migration, but one of these three is the rush of three hundred "dark grey birds larger than a common Thrush"[15] on Oct. 28th, at Point of Ayr. [Footnote 15: We shall refer to these under "Birds unknown," but we have thought it advisable to enter them here also; they can easily be erased in future comparisons if better data come to hand.]
