CATALOGUE OF THE BIRDS OF SUFFOLK. 9 1 



another of a light sepia colour shot about ten miles from 

 Bury St. Edmund's in the summer of 1851 (C. R. Bree in 

 Z. 3330). 



The following facts about "Rooks, recently observed in 

 Suffolk, may perhaps be interesting. At a 1'ookery at The 

 Thorn, Shimplingthorne, a complete change in their habits 

 has been observed. Some years back the Hooks used to 

 leave when the young had flown, and did not roost again 

 on the trees until February ; merely returning periodically 

 to examine and repair their nests. Now they stay all the 

 year round with an increase of their numbers in the winter, 

 and all the nests are destroyed to be re-built in the spring. 

 There is one particular tree on which a pair regularly begin 

 to build, but the nest is never allowed to be completed and 

 is always pulled to pieces by the other birds. This has been 

 observed for r some years. (Mrs. Tyrwhitt Drake in litt.). 

 At Cockfield Rectory Rooks attempted several times to 

 make their home, but never with success, till about four 

 years ago, when one pair built a nest ; a third bird was 

 always with them and sat on a neighbouring tree, cawing 

 as if to encourage them or perhaps to teach them the art of 

 nest-building. It was observed by two persons that the 

 bird which sat upon the nest had food brought to her by 

 both the others. One young bird was reared ; the following 

 year there were three or four nests, and last spring (1883) 

 more than twenty built in the place. (C. B.). The increase 

 of the numbers of the Rook in winter is doubtless due to a 

 partial migration. On the East Coast the arrival of Rooks, 

 Hooded Crows, and Jackdaws in 1879 from about the middle 

 of October to the end of December has been observed at the 

 Corton, near Lowestoft, and other Light-vessels (see Z. 3rd 

 S. iv. 181, and Hele, Aid. 88).
