waters. 
65. OLD SQUAW. Harelda hyemalis. 
Occasional winter visitant.

breeding birds remain through the summer. 
67. SURF SCOTER. Oidemia perspicillata. 
Abundant winter residents on bays and at sea. Both species

quent both fresh and salt waters.

Usually seen in flocks of considerable size. The food is mostly 
green vegetation, such as growing grain and grass.

Formerly common winter residents. Usually found in small 
flocks and sometimes singly. 
71. HUTCHINS GOOSE. Branta canadensis hutchinsi. 
Formerly common winter residents, now much diminished in 
numbers. 
72. CACKLING GOOSE. Branta canadensis minima. 
This small ‘‘Honker” probably comes this far south in winter, 
but I know of no example from this county in any collection. 
73. BLACK BRANT. Branta nigricans. 
Formerly rather common winter residents, now rare. Seldom 
found on fresh waters. 
74. FULVOUS TREE DUCK. Dendrocygna bicolor. 
Rather common spring migrant. Rare winter visitant. Strag- 
glers may remain through the summer and breed. Found on 
fresh waters. 
75. WHISTLING SWAN. Oloer columbianus. 
Rare winter visitants. 
Order HERODINES. Herons, Ibises, ete. 
Wading birds frequenting marshes or the borders of ponds, 
lakes and bays for food, catching frogs, minnows, insects or other 
aquatic forms of life of no economic importance except in a very 
general way. Most species are not edible. 
Family IBIDIDA. _Ibises. 
76. WHITE-FACED GLOSSY IBIS. Plegadis guarauna. 
Rather common spring migrants. Breed in small numbers 
about suitable marshes in the warmer valleys. Edible, the only 
species of the order found here that is edible. This is the ‘‘ Black 
urlew”’ of sportsmen. While externally they resemble curlews 
technically they are not at all closely related.
