144 THE ESSEX NATURALIST. December, 1886, at 9 a.m., two passed to Essex shore and remained about till noon. Hooded Crow Corvus cornix cornix L. Carrion-Crow Corvus corone corone L. Rook. Corvus frugilegus frugilegus L. Jackdaw. Coloeus monedula spermologus (Vieill.). Movements at light-stations. 1879. South of the Humber the migration of Rooks was noted at nearly every station as either Rooks or Black Crows to distinguish them from the Hoodie or Grey Crow. Both Rooks and Hooded Crows appear to have started simultaneously on 15th October and passed across the North Sea from E. to W. in almost continuous flocks on the 16th and 17th, and after these dates in more scattered detachments, less and less to 19th November and again during the latter part of December. 1880. Hooded Crow : At Galloper L.V. 24th October to 9th November, many flocks ; at Swin Middle L.V., 22nd October, noon to 3 p.m., with Rooks. Rook : Enormous as have been the numbers of Crows crossing the North Sea the Rook has probably quite equalled them. The Rooks are recorded from Spurn to the South Foreland, the majority into the southern counties. Each (Crows and Rooks), however, came from and travelled to the same points of the compass, E. to W. or N.E. to S.W., or S.E. and S. to S.W. Jackdaw : at Galloper L.V. 17th October, at 7.45 a.m., Rooks and Daws, three to four hundred. 1881. Hooded Crow : In the autumn are recorded at nearly all our stations from the Inner Farne to the Goodwins. There was a great arrival also on the English coast on the nights or early mornings of 18th and 19th October, at north, middle and south-east stations. Rook : in the autumn at some mid and south-east stations. Great rush 17th and 18th October, also 25th to 27th same month. 1882. Hooded Crow : Orfordness L.H., 19th September, first seen. In large numbers through October and November, at stations from Fame Islands to Goodwin L.V. ; great rush 11th and 13th. As a rule, few Hooded Crows cross south of Landguard Point and few Carrion Crows north of Spurn. Rook : Sparingly north of the Humber and in large numbers at the southern stations throughout October and November and on to the middle of December.
