of Jackdaws seen but as the finest dust ; of many birds only 

 heard call-notes without being able to see them; wind S., S.E., 

 and E. by S. 



Carrion Crow, C. corone, Linn. — First at Orfordness l.h., 

 Sept. 23rd, seven to N.E. ; and at several stations from Fame 

 Inner l.h. to Goodwin l.v., in October, November, and December; 

 sometimes with Hooded Crows, occasionally in separate flocks. 

 On Oct. 9th, at Spurn, Mr. Hewetson shot a Crow from a flock 

 passing inland, which had a few white feathers under the]chin and 

 some of the claws white. Heligoland, Oct. 27th, a small flight. 



Hooded Crow, C. comix, Linn. — Spring : Spurn l.h., March 

 11th, to S., many all day. Corton l.v., from March 21st to 

 April 14th, large numbers of Eooks and Hooded Crows going 

 from W. to E. Heligoland, March 2nd, flights high over head 

 to E. ; March 4th, same ; 12th, N.W., clear, great flights to E. ; 

 13th and 14th, same ; and to 17th, pretty numerous daily ; 

 April 8th, very many high overhead; 9th, same; 11th, great 

 many. Longstone l.h., April 31st, eleven came on island, 

 appeared much fatigued, and then left for land, mod. gale 

 N.N.W. Inner Fame l.h., 16th and 17th, many to W.S.W. ; a 

 great many Crows (Rooks ?) same time. Autumn : Orfordness 

 L.H., Sept. 19th, first seen, one. In large numbers through 

 October and November at stations from Fame Islands to Good- 

 win light- vessels ; great rush Oct. 11th and 13th. Nothing 

 special to note of migration across Heligoland in the autumn, 

 which as usual was in immense numbers in October and 

 November. As a rule, few Hooded Crows cross south of Lan- 

 guard Point, and few Carrion Crows north of Spurn. Rooks and 

 Jackdaws sparingly north of Spurn, and gradually increase 

 southward ; and most plentiful at southern stations. 



Rook, C.frugilegus, Linn. — Spring: Heligoland. Feb. 22nd, 

 N.W., a very great flight; 28^h, several flights going due E.; 

 March 4th, same ; 13th and 14th, less. Autumn : Sparingly 

 north of the Humber, and in large numbers at the southern sta- 

 tions throughout October and November, and on to the middle of 

 December. Immense numbers remain in North Lincolnshire 

 during the winter, feeding in the lowlands on both sides of the 

 Humber, and moving in the afternoon to the high wolds, where 

 at dusk they retire to the great wpods to roost. 



Raven, C. corax, Linn. — Whitby l.h., May 20th, one, ''comes 

 each year about this time."
