Hab. NortH AMERICA, rare on the Atlantic coast, breeding far to the northward, in 
winter south to Cape San Lucas§.—Mexico (Wagler'), Mazatlan (Grayson *), 
Guanajuato (Dugés*), Valley of Mexico (Herrera !°11), savannas of Nopalapam, 
Vera Cruz, and Santa Maria del Mar, Tehuantepec (Sumichrast°), San Marcos, 
Puebla (Ferrari-Perez °)—Cusa®; Coast or Eastern Asia, Japan °. 
This Goose differs from the European A. albifrons only in its larger size. It breeds 
in great numbers in Arctic America and on the islands of the Polar Sea, passing 
north, in large flocks, at the same time as the Snow-Goose. ‘The species goes south in 
autumn and ranges as far as Mexico, where it is a regular winter visitant. According 
to Grayson, A. gambeli appears in considerable numbers at Mazatlan from September 
to February, and the bird occurs on both coasts, as Sumichrast speaks of large 
flocks in Tehuantepec and Vera Cruz. Ferrari-Perez records it from San Marcos in 
the State of Puebla, and Herrera from the Valley of Mexico, where its native name is 
“ Talacatl.” 
The habits of this bird do not differ from those of other northern Geese, but it 
seems occasionally to make a more substantial nest than some of its allies—a depression 
in the ground being well lined with hay, down, and feathers. In Alaska, however, 
Mr. Dall found the eggs laid in a hollow in the sand without any lining whatever. 
‘The eggs vary from six to ten in number, and are indistinguishable from those of the 
Snow-Goose. .

outside, as in Chen and Anser, and the tomium is almost straight. Count Salvadori
