feathering on the head and neck, and the different distribution of the plumes on these 
portions of the body, have been deemed by some recent writers to be of sufficient 
importance for the separation of many of the Cranes into distinct genera, but this » 
division does not commend itself to us. 
The genus is represented in the northern portions of both hemispheres during the 
summer, the species migrating south in winter. All the Cranes more or less resemble 
each other in habits.

Hab. Arctic anp Suparctic Norta America, breeding from the Fur Countries and 
Alaska to the Arctic Coast, migrating southward in winter into the Western 
United States °9.—Mexico, Mazatlan (Grayson +), San Luis Potosi (Jouy '), 
Guanajuato (Dugés*), Valley of Mexico (Herrera®’), Tizimin, Yucatan 
(Gaumer }°). 
The Little Brown Crane visits Mexico in winter on migration, when it leaves its 
breeding-home in the high north. Grayson‘ says that it makes its appearance in 
Mazatlan in considerable numbers as early as the month of September, disappearing 
again before the end of March. Jouy writes!! that this bird was numerous in 
winter time at the Hacienda Angostura in San Luis Potosi, frequenting the cultivated 
fields; it was often seen in large flocks circling high in the air, its loud cry being 
distinctly heard, even when the birds were almost out of sight. A single specimen 
was also shot at an ‘“‘aguada” near Tizimin in March, and this was the only example 
observed by Dr. Gaumer in Yucatan 7° 
G. canadensis arrives at its Arctic breeding-place in the early part of May, and is 
very plentiful in the marshy grounds which it affects. The nests are placed on dry 
knolls, but they sometimes consist merely of a large depression scooped out in the 
sand and lined with dry grass.
