THE JACKDAW {Corvus monedula). 



All the records of the Jackdaw were received from the Suffolk coast, 

 but it is prohable that many lightship records of " Rooks " and " Crows" 

 relate also to this species. The earliest migratory movements were noted 

 on the 2nd of March and continued on all suitable days until the 22nd of 

 April. On that part of the coast (Lovrestoft) there would appear to be 

 two lines of migration ; the majority of the flocks (which generally in- 

 cluded Rooks) collected on the coast fields, often after having arrived 

 from the west (inland), and then proceeded east or south-east, quite 

 independently of the direction of the wind. Now and then a single 

 flock was noted going due south. On seven days between the 30th of 

 Marcb and the 22nd of April (only) flocks were observed to take a N. or 

 N.E. direction, while on the 10th of April flocks were also noted going N.E. 

 in the south of Suffolk. Fog or haze at sea appeared to stop migration, 

 and no movement seemed to take place during N.E. gales with snow ; a 

 few birds, however, were seen to start on migration in the face of a strong 

 east wind, but this acted as a deterrent to the majority. 



THE ROOK {Corvus frugilegus). 

 TflE HOODED CROW {Corvus coriiix). 



As the light-keepers do not as a rule distinguish between these two 

 species, and as they are generally associated while on migration, they 

 are treated under one heading. 



On the 3rd of February a flock arrived on the coast of S.E. Suffolk and 

 on the 28tb and following days flocks were reported as flying N.W. past 

 the Shipwash and Kentish Knock Light-vessels, and at the latter station 

 again on the lltb of March. Migration was first noticed at Lowestoft 

 (N.E. Suflblk) on the 2nd of March, and on most days during that month 

 and up to the 22nd of April flocks of Rook?, with Hooded Crows and 

 Jackdaws, collected on the coast fields, often coming from the west on 

 migration. These generally departed in an easterly direction, though 

 some went S.E. This movement was also observed at the Corton Light- 

 vessel (Suffolk). On six days between the 30th of March and the 22nd of 

 April (only), as in the case of the Jackdaw, flocks were observed going 

 N. or N.E. The remarks made above (lide Jackdaw) with regard to the 

 weather apply equally to these two species. In N.W. Suflblk numbers 

 of Rooks were seen during the latter part of March collecting or moving 

 off to the east. Flocks were seen at Coquet Island (Northumberland) 

 going west on the 23rd and 31st of March and on the 8th and 17th of April, 

 while at South Bishop Light (Pembroke) a few were noticed going east 

 on the 25th of March. The only other record in the west came from More- 

 cambe Bay Light -vessel (Lancashire), where two birds were noted going
