perfect winter plumage, from which its name is derived, was shot 
on the 24th of November at Beeston, near Cromer, but a male, 
shot on Breydon on the 15th of December, still retained traces of 
its summer plumage on the throat, neck, and wings. 
Norfolk Heronries. The pair of herons which I noticed last 
year as having nested and reared their young in the Keswick 
rookery, near Norwich, a former haunt of this species, returned to 
the same spot this spring, hut, from the persecution of the rooks, 
failed to establish themselves a second time. At Sheringham, 
near Cromer, a single pair, as Mr. H. M. Upcher informs me, 
have reared their young, both this year and last, stragglers, pos- 
sibly, from the flourishing colony in Gunton Park. 
Books migratory. A large increase of rooks, (apparently 
migratory) accompanied by great numbers of jackdaws, was 
remarked both at Northrepps and Sheringham on the 7th of 
November. Mr. Gurney has remarked for some years the annual 
arrival of rooks on our coast from across the German Ocean, in the 
months of October and November, but this year the number of 
these migrants was considerably larger than usual.* 
Magpies. On the 24th of December seven magpies were seen 
together on a hedge at Weyborne, and on the 30th six were 
observed in the same spot. So scarce has this species become of 
late years, in this game preserving county, that there is little 
doubt these were recent arrivals on that part of the coast, and it is 
not the first time I have heard of as many being seen at one time 
at Weyborne. A pair of these birds were shot on the 4th of May 
at Tylney All Saints, on the opposite side of the county, which 
possibly might have remained to breed. 
* In the ‘Zoologist’ for March, 1876 (p. 4S37), Mr. Cordeaux quotes 
as follows from a letter, dated Christmas Day, 1875, from Mr. Giitke, of 
Heligoland. “ An abundance of rooks there has been, as nobody ever 
witnessed before on this island ; these last ten years together have certainly 
not seen here so many of these birds as this one autumn alone.” See also 
a note in the ‘ Field,’ Feb. 12th, 1876, from Mr. It. Collett, of Christiania* 
on the periodical migration of rooks to and from the south coast of 
Norway.
