158 BIRDS OF CHESHIRE. 
the species in a county avifauna. Canada Geese may 
nearly always be seen on the meres at Marbury near 
Northwich, Rostherne, Tatton, Mere, Arley, Capesthorne, 
and Alderley, and frequently on smaller sheets of water 
or even secluded ponds. In the winter it is not unusual 
to see flocks, varying from half a dozen to two or three 
hundred birds, feeding in the fields, or flying from one 
sheet of water to another. 
Examples of the Egyptian Goose, Chenalopex cegypti- 
aca (Linnzeus), a species kept on many private waters, 
have been sometimes obtained; and about forty years 
ago a Bar-headed Goose (Anser indicus, Stephens) was 
shot on the marshes at Burton;! but there can be 
no doubt whatever that these birds had escaped from 
captivity. 
WHOOPER. 
Cyanus musicus, Bechstein. 
The Whooper is a not infrequent visitor in winter 
to the Dee and Mersey Estuaries. Byerley says that 
examples have been seen near Upton and Leasowe,? 
and Brockholes records that in the winter of 1870-71, 
Mr. Lawton of Denhall shot one in the estuary of 
the Dee* This was no doubt one of the herd of 
about thirty birds that Mr. A. O. Walker saw on 
January 12th, 1871, between Bagillt and Holywell, 
on the Welsh side of the estuary. Dr. Dobie has 
occasionally heard of Whoopers being seen on the 
Dee Estuary and on the Mersey near Ince.*
