Gulls, Larinæ.--The Herring Gulls returned to their breeding stations at Whitby on Feb. 14th; they left the cliffs with their young on Aug. 26th. Lesser Black-backed Gulls were observed congregating at their nesting quarters, on the Farne Islands, on April 13th. At Flamborough, on July 4th, great numbers of Kittiwakes were passing to the south all day. Unusual numbers of Herring Gulls and Little Gulls (_L. minutus_, Pall.) were seen off Flamborough in September. At Spurn, on Oct. 26th, two Little Gulls were seen; and about the 22nd two immature Sabine's Gull, _Xema Sabinii_, procured on the Norfolk coast, some Little Gulls being seen at the same time. At Teesmouth (Redcar), on Sept. 22nd, continuous flocks of Herring and Lesser Black-backed Gulls, young birds, passed from daylight to dusk, all going N.W., strong E. gale, rain. On Oct. 23rd, and for several days previous. Great Black-backed Gulls had been passing to N.W., forty to one hundred in the course of a day, E.S.E. winds, all mature birds. It is many years since so large a number of Great Black-backs had been seen passing. At the Cockle L.V., on Nov. 11th, continuous flocks of Gulls were passing westward all day; and on Dec. 29th, at Lynn Wells L.V., flocks all day from E. to W. Skuas, Stercorariinæ.--On July 12th, a flock of one hundred (probably _S. crepidatus_) passed at 8.30 p.m. to N.W., high over Redcar, wind W. On Sept. 16th a great many Skuas were seen on the fishing grounds, five to six miles out, Richardson's, Pomatorhine, and Buffon's busily engaged chasing the Gulls and Terns; and again on Sept. 29th, a great many Richardson's, Pomatorhine, and a few Buffon's Skuas seen from four to twelve miles at sea by fishermen similarly employed. On Oct. 14th, during the gale from N.N.W., great numbers of Pomatorhine came down from north, passing Redcar and going off inland, mostly flying high. The same day a large mixed flock of Pomatorhine and Buffon's Skua was seen near the Breakwater, crouching on the ground to get shelter from the tempest of wind and rain. Great numbers of Skuas passed Flamborough in September; on Oct. 4th, four Richardson's Skuas were seen off Yarmouth; and on Nov. 23rd, at Southsand Head L.V., great numbers ("Bonxie's and chasers") with Gannets.
