Note 10 — EAST COAST OF ENGLAND.

Mr J. H. Gurney, Sen., writes:—"Lord Lilford sends me word that on 20th of March 1886, Mr G. Hunt saw an extraordinary flight of Rooks at Somerton, which he observed from 10.30 A.M. till 6 P.M., when he left, but the flight was still going on. He wrote to Lord Lilford:—'I observed them flying just above the sandhills, going due south, and as far as the eye could see both before and behind there was nothing but Rooks. There would never for one moment of the day be less than a thousand in sight at one time; they kept in a thin wavering line. The coast line here runs due north and south.'" Mr J. H. Gurney, Jun., writes:—"I saw the same Rooks and Grey Crows on the same day in much smaller numbers as were seen at Somerton (Norfolk coast), which is fifteen miles further south. I again saw them on the 21st, 22d, 25th, 26th, 29th, but none after that date. Mr Hunt says they were all Rooks, but with me Grey Crows preponderated; direction to S.E." In connection with this read Mr Gätke's notes of migration as observed at Heligoland and Hanover between March 19th and 25th, 1886, on the last page of his journal.
