Foster on the Birds of Hillsborough. 
[The Birds of Hillsborough. By Nevin H. Foster, M.B.O.U, Proc. 
Belfast Nat. Hist. & Philos. Soc. 1920-1921, pp. 1-19 (separate 
pagination).] 
Hillsborough is a small town in the north of County Down; 
it is a short distance from Belfast, and is the centre of a 
somewhat highly cultivated district. Mr. Nevin Foster 
has in this paper compiled a list of the birds of the neigh¬ 
bourhood, chiefly from his own notes, dating back to 1902. 
The list embraces 109 species, out of which 76 have been 
known to breed in the district. 
Several rare species such as the Golden Oriole and the 
Alpine Swift, the records of which are not entirely satisfac¬ 
tory, are included in the list, but placed in square brackets. 
Gurney’s Ornithological Report for Norfolk. 
[Ornithological Notes from Norfolk for 1920. 27th Annual Report. 
By J. H. Gurney, F.Z.S. Brit. Bds., London, xiv. 1921, pp. 242-252.] 
Mr. Gurney's annual report on Norfolk ornithology 
contains the usual summary on migration and a series of 
classified notes. There were no events of unusual im¬ 
portance during the year, but the Curlew is believed to 
have bred again near King's Lynn and the Sandwich Tern 
at Blakeney. The Spoonbills came to Breydon in May and 
stayed about three weeks, though they did not breed, but 
the Bitterns are now becoming comparatively common, and 
many nests are located every year.
