CINNAMnN TEAL. 35 
Winter nimh. The cinnamon teal of North America retires iii 
winter but little south of it< breeding range in Mexico as Ear as Ma/at 
Ian, Guanajuato, and the Laguna de Chapulco, Puebla. It isfoundal 
this season as far north as Brownsville, Tex., central New Mexico, 
southern Arizona, and Tulare Lake. California. South of Mexico the 
only record IS of an accidental occurrence in (\»ta Rica. There 18 DO 
reliable record as vet for the Wesl Indies. 
During the winter season the cinnamon teal of the Southern Hemi- 
sphere has been noted as far south as tin 1 mouth of the Senevr River, 
in Patagonia, latitude -41 S.. and Chiloe Island. Chile, in nearly the 
same latitude. The northern range in winter is not determinable With 
exactness from present data. The species passes north to Rio Grande 
do Sul, Brazil, and to southern Paraguay. It has been noted at 
Chorillos and Tungasuca, Peru; near Quito, Ecuador; at Bogota and 
Santa Marta. Colombia. These Ecuador and Colombia teal may lie 
accidental occurrences; it is significant, at least, that all the specimens 
from Colombia were taken a half a century ago, and the species has 
not been noted there by recent collectors. 
Spring migration* — The northward movement of the cinnamon teal 
in the United States begins about the 1st of March, and arrivals have 
been noted at Ash Meadows, Nevada, March 18, 1891; Grangeville, 
Idaho, April 11, 1887; Chilliwack, British Columbia, April 24, 1888, 
and April 22, 1889; Beloit, Colo., March 23, 1892; Colorado Springs, 
April :». L882; Loveland, Colo., April 13, 1890; Lay, Colo., April 20, 
1890; Omaha, Nebr., April 10, 1896, and April 12, 1897; Lake Oomo, 
Wyoming, about May 5. 
FaU migration. — Southward migration occurs chiefly in September, 
and the northern portion of the breeding grounds from British Co- 
lumbia to eastern Colorado is deserted about the middle of October. 
Migration in Soitih America. — The cinnamon teal of South Amer- 
ica is migratory in at least part of its range, for in central Argentina 
it is abundant during the winter season, April to September, and rare 
or lacking during the breeding period. The species is migratory also 
in the southern portion of its range in Chile. In northern Chile and 
in Peru migration records are wanting. The time and direction of the 
migration of this species in South America correspond closely with 
those in the United States, but of course the breeding and wintering 
seasons are reversed, since they are on opposite sides of the equator. 
Thus the cinnamon teal is distributed in two distinct colonics, part 
of the individuals breeding far north of the equator, and the rest 
about an equal distance to the south. The northern breeders migrate 
south after nesting, and the southern breeders migrate north. Whether 
or not the members of these two groups now represent subspecies, they 
are so much alike as to indicate a common origin and a former con- 
tinuous breeding range. Whether isolation was gradual or was effected 
rapidly it is impossible to say, nor do we know the cause.
