Dafila acuta, Baird, Gen. Rep. IX, 776. 
Plentiful, especially so in spring, when they collect in large flocks on the open plains and 
about the fresh water ponds previous to migrating northward. 
ANAS BOSCHAS, L i nn .—Mallard. 
Anas boschas, Gmel. Syst. Nat. vol. I, part II, p 538.— Nutt. Ora. vol. II, p. 379.— Aud. B. of A. Oct. vol. VI,

abundant; breeding wherever a suitable and secure locality offers, having found its nest in 
the marshes, on the edges of small fresh water ponds, and once also in a wild oat field at some 
distance from water. The Indians entrap these as well as other ducks in a weir constructed of 
willow branches and shoot them with arrows from ambushes built on the shore. 
QUERQUEDULA CAROLINENSIS, Gmel.—Green Winged Teal. 
Anas carolinensis, Gm. Syst. Nat. vol. I, part II, p. 533.— Aud, B. of A. Oct. vol. VI, p. 281, pi. 392. 
Nettion crecca, Baird, Gen. Rep. IX, 778. 
Abundant in California, having procured it as far south as Carissa creek on the borders of the 
Colorado desert. 
QUERQUEDULA CYANOPTERA, Vie ill.—Red-breasted Teal.

Anas rafflesii, King, Zool. Journ. vol. IV, p. 97. 
This beautiful teal is abundant in California during spring and summer, incubating on the 
marshes and migrating south on the approach of winter. Its nest is composed of coarse grasses, 
lined with the down taken from its own breast, and contains from twelve to fourteen eggs of a 
faint green color. I found this species in January near San Diego and at a later period in 
Texas near Fort Thorne, where Dr. C. Henry, United States army, informed me that it was 
quite a common bird. Its habits and flight, as far as observed, are similar to those of our blue 
wing teal, (Q. discors.) 
CHAULELASMUS STREPERA, Linn .—Gadwall Duck. 
Anas strepera, Gmel, Syst. Nat. vol. I, part II, p. 520. — Aud. B. of A. Oct. vol. VI, p. 254, pi. 388. 
Not rare, and some few pair incubate in the country, as I have procured the eggs in the marshy 
districts of Sacramento valley during the spring. 
SPATULA CLYPEATA, Linn .—Shoveller Duck. 
Rynchaspis clypeata, Gould. B. of Eur. vol. V, pi. 360. 
Anas clypeata, Gmel, Syst. Nat. vol. 1, part II, p. 518.— Wils. Am. Ora. vol. VIII, p. 65, pi. 67, fig. 7.— Nutt. Ora. vol. 
II, p. 375.— Aud. B. of A. Oct. vol. VI, p. 292, pi. 394 
Plentiful, preferring the fresh water ponds and streams, where it is found associated with the 
teal and mallard. I procured it as far south as the Big Lagoon of the Colorado desert.
