MIGRATION OF BIRDS IN N.E. LINCOLNSHIRE. 207 



C. corone, Linn. Carrion-Crow. — Two or three Carrion 

 Crows appeared on Tetney "fitties" on Oct. 13th. On the 23rd 

 I noticed over a hundred of these birds coming in to roost in 

 Fenby Top Wood, a considerable increase in their numbers 

 having apparently taken place about this time. 



C. vornisc, Linn. Grey Crow. — Two on the sea-bank at North 

 Cotes on Sept. 27th, but no more until Oct. 8th, when a couple 

 were seen at Grainsby. Grey Crows took part in the great 

 movement of Oct. 20th, and were passing to N.W. along the 

 shore all day until about 3 o'clock, either singly or in small 

 parties of four or five flying close to the sand. 



C.frugilegus, Linn. Rook. — The Eook was almost the only 

 bird whose immigration during the past autumn assumed unusual 

 proportions. Commencing on Oct. 8th, the passage of this bird 

 reached its height on the 20th, and terminated about Nov. 1st. 

 The flight of Oct. 20th was one of the largest that I have ever 

 witnessed. On reaching the coast I observed an unbroken 

 stream of Eooks travelling steadily to the N.W., almost in the 

 teeth of a stiff N.N.W. breeze. The flock was scarcely more 

 than fifty yards wide, and the birds were flying close to the 

 ground, only rising to clear hedges, trees, or buildings which 

 obstructed their line of flight. I watched the passage for 

 about half an hour, and it was still progressing when I left. 

 Numerous other flocks, large and small, were also coming in 

 from the sea ; but the passage came abruptly to an end at 

 one o'clock. 



Alauda arvensis, Linn. Sky-Lark. — The Sky-Lark was less 

 numerous on migration than usual. The passage took place, 

 between Oct. 12th and 20th, the direction of flight being generally 

 N.W. On loth, however, the flocks were moving S. And on 

 the 20th, although the bulk were passing N.W., several flocks 

 went S.W. 



Dendrocopus major (Linn.). Great Spotted Woodpecker. — I 

 saw one of these Woodpeckers at Fenby on Oct. 21st, and a 

 second at Grainsby on 26th. 



Cuculus canorus, Linn. Cuckoo. — On July 16th I observed 

 two Cuckoos on hedges near the coast. 



Asio otus (Linn.). Long-eared Owl. — I flushed two or three 

 of these Owls in a small plantation near the sea shore on
