by a black patch, and a more or less distinct white half collar on, the

than B. c. hutchinsit. Length 23-25 ; wing 14-0 ; culmen 1-0; tarsus 2-6, 
Distribution—Breeding in Alaska and the Aleutian Islands; in 
winter from southern, British Columbia to southern California; else-

The Cackling Goose is a rare straggler to Colorado. One specimen, 
only has been identified (Cooke) ; this was shot near Loveland, April 
10th, 1898, by Mr. J. F. Campion, and is now in the State collection 
in the Capitol at Denver. 
This example appears to me to be more properly referable to 
Hutchins’s Goose than to this species. It is the only definite record.

Description. Adult—Head, throat, neck and upper-breast black ; 
a little white mottling on the sides of the neck; back brownish-grey 
margined with lighter; longer lateral upper tail-coverts white ; lower-

sides ; iris brown, bill and feet black Length 24-0; wing 13-0; tail

Young birds are very similar, but have less white on the sides of the 
neck and the wing-coverts and secondaries are white tipped. 
Distribution.—Breeding on, the west coast of Greenland, and as 
far north as land extends; south in winter to the Atlantic coast from 
New Jersey to Florida; a straggler only elsewhere. 
There is only one recorded notice of the occurrence of the Brant in 
Colorado. Captain Thorne shot a specimen at Fort Lyon, April 11th, 
1883. Though not preserved, there can be little doubt about its 
identification. 
Subfamily CYGNINZ. 
The Swans resemble the Geese, having reticulate tarsi, 
a simple unlobed hallux and sexes alike ; they are dis- 
tinguished from them by their long necks, and by having 
the lores between the eye and the bill naked and without 
feathers—at least in the adults. 
Genus OLOR. 
In addition to the above-mentioned characters, the prevailing 
colour of the plumage is white, and normally the trachea is prolonged 
and coiled in 2 cavity in the sternum. 
Several species in the northern hemisphere and South America.
