ANAS DISCORS 
Escondido in the same State. It is said to winter in great flocks on Lake Nicaragua (Rendahl, 1919). 
It is an abundant bird on the Pacific coast of Costa Rica (Carriker, 1910) and has been foimd in that 
country by Zeledon, Cherrie, Calleja and von Frantzius (JUe Salvin and Godman, 1897-1904). In 
Panama also it is found in winter (de Armas, 1893; W. Stone, 1918), and is said to be abundant 
(Jewel, 1913). 
In the Pacific Ocean the Blue-wing has been found on Clipperton and Cocos Islands, and on 
Pacific Albemarle and Chatham in the Galapagos group (Gifford, 1913). Its winter status 
Islands in South America is not wholly clear. Evidently it straggles far south, but it is prob- 
ably of regular occurrence on the north and northwest coast only and outside the hea\'y forest 
regions. The British Museum has specimens from Medellin and Bogota (Colombia) 
Colombia and A. A. Allen found the species not uncommon near Cali (fide F. M. Chapman, 
1917). F. M. Chapman (1917) took specimens at Cali and Puerto Valdivia. It is 
rather common in Ecuador and has been taken at Quito (U.S. Biological Survey), at Colta (Chubb, 
1919), at Esmeraldas and at Chone Venavi in October, December and January 
(American Museum of Natural History), and at La Carolina (Lonnberg and Rendahl, 
1922). The British Museum has a specimen from Lima, Peru, and Beck took another at Lake 
Junin in March (Brewster-Sanford collection). The southernmost record is for Ovalle, 
Chile (Schalow, 1898). 
In Venezuela specimens have been taken at the Lake of Valencia (P. L. Sclater and Salvin, 1869b), 
Venezuela Zulia (Ernst, 1877) and in the same general region by Osgood and Conover 
Guiana (1922). C. B. Dawson (1916) and Chubb (1916) have recorded it from British Guiana 
and the Penards (1908-10) say it is common in Dutch Guiana in November and 
December. Von Berlepsch (1908) includes the species in his list of the birds of Cayenne. There is 
even a record for Brazil (von Pelzeln, 1868-71), but it seems to be open to doubt. 
This species is known to have straggled several times to western Europe. A specimen was taken 
in Dumfries-shire, Scotland, in January, 1858 or 1863 or both; another in Cheshire, England, 1860; 
a third at Ballycotton, county Cork, Ireland, September, 1910, and possibly a fourth 
in Cambridgeshire (British Ornith. Union Checklist). Degland and Gerbe recorded 
a specimen for Normandy, which was probably the same one recorded by van Schauberg as having 
been taken on the Straits of Dover in 1857. Another specimen was taken on October 24, 1899, at 
Dokkum, Province of Friesland, Holland (van Oort, 1922), and there is also a record for Den- 
mark, at Saby, northeastern Jylland, April, 1886 (Winge, 1888).

Migration 
Throughout the entire central and northeastern section of the United States this Teal is known 
primarily as a bird of passage. Such is the case in Colorado, Wyoming, South Dakota, Nebraska, 
Kansas, Iowa, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York and the New 
England States. In eastern Canada and even in Quebec and Ontario, as in Wisconsin and Michigan, 
it is also seen primarily during the migration season. The species is the least “hardy” of the ducks 
and leaves late in the spring for its breeding areas, while it is the first to start south in the autumn. 
It does not appear to leave its winter quarters until the middle of March when its numbers become 
greatly increased in southern Texas. During early April it reaches its greatest abundance in Louisi- 
ana, though it stays in the Gulf regions until well into May. It reaches the central States in April, 
earlier in the east apparently than in the west. By late April or May it arrives at the breeding 
grounds in the northern States and in south-central Canada, on the average at least three weeks 
after the Mallard. 
In the autumn the species begins to move throughout the northern States as early as August, and 
by the first half of September it has beeome common. I have seen a single specimen in Massachu-
