MIGRATION OF BIRDS IN N.E. LINCOLNSHIRE. 127 



Crows in number. On Dec. 1st I saw a flock of quite two hundred 

 in a stubble-field outside Autby Wood — a favourite roosting-place. 



C. comix, Linn. Grey Crow. — A few appeared on Oct. 5th. 

 I noticed a good many inland on the wolds on 15th, mostly 

 flying west. 



C.frugilegus, Linn. Rook. — Numerous on grass-land in the 

 vicinity of the coast on Oct. 2nd. On 22nd single Rooks were 

 coming in and going W. at short intervals, until one o'clock ; 

 almost all appeared to be old birds. On 25th they were still 

 coming in in straggling flocks from E. to W. until two o'clock, 

 both old and young birds travelling together. On Nov. 29th a 

 similar migration took place, the flocks moving in the same 

 direction until two o'clock. As far as I could see the last con- 

 sisted entirely of young birds. 



Alauda arvensis, Linn. Sky-Lark. — Very little visible migra- 

 tion, but the species was present in its usual numbers during the 

 winter. On Oct. 3rd small parties were going N.W. all day. On 

 the 4th a few flocks going N.W., and a smaller number going S. 

 On 22nd large flocks coming in from the sea from E. to W., and 

 on Dec. 1st a few passing S.W. over Grainsby. 



Cypselus apus (Linn.). Swift. — Last Swifts seen on Aug. 

 23rd. The majority left before the middle of the month. 



Dendrocopus major (Linn.). Pied Woodpecker. — Fairly 

 numerous in the winter. I saw the first at Grainsby on Oct. 

 3rd. One was said to have been killed on the Tetney sea-bank 

 on Nov. 16th, and on 26th I saw two recently killed young birds 

 at a Grimsby birdstuffer's. 



Alcedo ispida, Linn. Kingfisher. — First seen on Saltfleet 

 Haven on Sept. 6th ; a second at North Cotes sluice on 25th, 

 and several along the sea-bank on Oct. 4th. 



Coracias garrulus, Linn. Roller. — In the ' Field ' of Oct. 5th 

 Mr. L. D. Marsden notes the appearance of a Roller, which was 

 seen at Brackenborough, near Louth, on Aug. 29th, and again 

 on Sept. 26th. 



Cuculus canorus, Linn. Cuckoo. — Fairly numerous at Grainsby 

 during the last week of August. Last seen near Scarthoe on 

 Sept. 9th. 



Strix flammed, Linn. White Owl. — A single Barn-Owl in 

 a small plantation near the coast at Tetney on Oct, 9th,
