wickshire (Tomes) ; Stafford (Buchanan) ; Shropshire 
(Shaw); Cumberland (Heysham); Northumberland 
(Hancock); and Aberdeenshire (Macgillivray and 
Robert Gray). 
Mr. J. H. Gurney states that, besides being a sum- 
mer visitant, this species arrives as an early autumnal 
migrant on the east coast, and the birds so arriving 
are mostly birds of the year. 
MARSH HARRIER. Circus wruginosus (Linneus). 
Formerly common in the English fens, but now 
seldom observed, except as an irregular visitant, and 
generally in autumn; nevertheless it still breeds occa- 
sionally in a few English counties. Mr. Thompson 
considered it resident in Ireland, where he found it 
generally distributed in suitable localities. In Scot- 
land it is much rarer, and breeds there but seldom. 
HEN HARRIER. Circus cyaneus (Linneus). 
A local resident; occurring as an autumnal migrant 
in small numbers to the eastern counties. 
MONTAGU’S HARRIER. Circus cineraceus (Montagu). 
A local resident in England, rare in Scotland, and 
unknown in Ireland. It occurs as an autumnal 
migrant in small numbers in the eastern counties of 
England.
