S. Bishop Light (Pembroke) on the 20th/21st, while on the 27th a flock 

 was noted going south at Morecambe Bay Light-vessel (Lancashire), 

 During December there were only a few records of single birds. 



THE NUTCRACKER [Nucifraga caryocatactes). 



During the autumn (1911) one of the periodic irruptions of this species 

 occurred. The birds first appeared in the Russian Baltic provinces and 

 Kurland at the end of July. Here they became very numerous towards 

 mid- August and diminished in numbers at the beginning of September. 

 A flock was seen in W. Prussia also, towards the end of July, which 

 appears to have dispersed westward during August and September, but 

 none were recorded from E. Prussia until the end of August. From the 

 beginning of the second half of September the birds spread to Pomerania, 

 Mecklenberg, Prussian Silesia and Hanover, and by the end of the month 

 they had reached Mark Brandenberg, Bohemia, Lower and Upper Austria, 

 Croatia and Dalmatia. At the beginning of October they were reported 

 from S. Styria, Bavaria, Eisass, Westphalia, Northern and Central 

 France, while at the end of the first week they reached the British 

 Islands. 



One was shot at Cawston (Norfolk) on the 6th, a second at Whit- 

 church (Bucks) on the 7th, a third at Sparham (Norfolk) on the 9th, a 

 fourth at Broome (Kent) about the same time, a fifth at Beyton (Suffolk), 

 where it had been seen for at least a week, on the 9th of November, and 

 a sixth at Brede (Sussex) on the 2nd of December. 



All the specimens, both Continental and British, that have been 

 examined, have proved to belong to the Siberian or slender-billed race 

 (xY. c. inacrorhynclms). 



THE JACKDAW {Corvus monedula). 



The returns relating to this species were scanty. During the last half 

 of October flocks were noted in north Suftblk coming in from the east, 

 frequently accompanied by Rooks ; arrivals were also recorded inland in 

 Suffolk about the same time. On the 15th of October a single bird 

 occurred at Skerryvore Light (Inner Hebrides) and on the 30th at the 

 Leman and Ower Light-vessel (Norfolk). Further arrivals were noted 

 in north Suffolk, flying west, during the first week in November and 

 in S.E. Suflrolk on the 7th. On the 5th and 12th of November odd 

 birds were seen coasting south on the Northumberland coast, on the 7th 

 flocks were going west past the Leman and Ower Light-vessel, while 

 on the 10th arrivals were recorded at the Bell Rock Light (Tay) and on 

 the next day in Tiree (Argyll). On the 9th of December one was taken 

 on St. Kilda (Outer Hebrides).
