Pelecanidæ.--Solan Goose or Gannet, Cormorant, Shag, Scart, etc.--This year we give a day-by-day return of Solan Geese seen at N. Unst during September and October. We would like to complete a year's observations of the movements of this bird at the following stations:--N. Unst, Bell Rock, Pentland Skerries, Cape Wrath, Butt of Lewis, Monach Isles, Barra Head, and Ailsa Craig, and Turnberry on the coast of Ayrshire. We would also like daily returns made at Skerryvore or Dhuheartach [all negative evidence being carefully entered, such as "none seen" on such and such a date or succession of dates], and also at Rona, north of Raasay. A separate schedule or more might be devoted to Gannet or Solan Goose alone for every day in the year, noting carefully the direction of flight of flocks or individuals, or how employed. If we had such a series complete, we believe much light might be thrown upon migrations of fish in combination with work going on at Lochbuie in Mull, at the Marine Institute there. Solan 1886.
