Anatidæ.--Ducks, Geese, Eider Ducks, Teal, Widgeon, Shieldrake, Wild Duck, Barnicle Geese, Swans, Brent Geese.--_In Spring_ flocks, or large flocks, of Barnicle Geese are frequently noted at Cromarty, presumably the same flocks daily. (Barnicle is here undoubtedly applied wrongly to the Brent Geese, or "Brants," which are abundant in the Cromarty Firth.) Thus on 19th, 25th, and 26th February, and from 4th to 18th March, a "large flock" is almost daily noted; and thereafter none are again noted till November 24, when a flock again recorded, and two flocks on 25th and 27th December, all at the same place. _Eider Duck._--Odd birds noted off N. Unst in February 5th and 18th, and March 23d and 26th--winds different directions; and a flock of nine at Isle of May on 18th April. Odd records in May and June at N. Ronaldshay and at Fidra, probably merely local movements. _In Autumn._--Recorded as "making their appearance by the 5th September at N. Ronaldshay; and large flocks by the 11th September at Pentland Skerries. Flocks all day on several dates in October at N. Unst, and Fidra, &c." Teal are noted occasionally at Pentland Skerries in March on 1st and 2d. _Widgeon_ rarely noted: once in March at Isle of May, and once in October at Fidra. _Shieldrake_ once noted at Noss Head, and once on 15th November on Fidra. Wild Swans are noted on 12th April, and four on 25th at N. Ronaldshay; and thirty on one occasion at Sumburgh Head. _Note._--A most remarkable assemblage of Eider Ducks took place off the west shore of Harris, as seen and reported to me by James Cowan, Esq., M.P. He writes, under date of 18th March 1887: "Last year, owing to the easterly winds, we had not less than 3000 Eiders within four miles of our cottage, on the west coast of Harris; and the year before there was not one." Columbidæ.--Pigeons, Doves.--Rock Dove, Wood Pigeon, Turtle Dove.--A Turtle Dove was obtained at Isle of May on 31st May 1886; wind light S.E., and haze. An addition to the Isle of May list and collection; at present at Dunipace House. A single record of a Wood Pigeon, "seldom seen here," at Pentland Skerries on 18th June; and another at same place on 7th October, "flying west; rare "--fresh, variable, and haze. A single record of Rock Pigeons (a flock) on 20th at Pentland Skerries, and the remark, "seldom seen." There were twenty in the flock. Rallidæ.--Corncrake, Water Rail, etc.--Heard first time at Pentland Skerries on 19th May, and at Cromarty on 25th. Above are the only records of any of the Rails. Charadriadæ.--Plover, Golden Plover, Lapwing, Dotterel, Ringed Dotterel or Ringed Plover, Oyster-Catcher or Sea Pie, Grey Plover, Golden Plover.--_In Spring._--Movements scarce; in February (one record on 25th at Pentland Skerries); in March (one record at same).
