Behavior of bird: 

The two Cinnamon Teal were among a large concentration of other ducks, shorebirds, and waders that were assembling at dusk for roosting. Both teal were observed as they preened and generally were not very active.

Description:

The first individual spotted was more in eclipse plumage, but had a strongly cinnamon-washed head, longer, more spatulate bill than Blue-winged Teal (but less so than Shoveler), and had a red iris. The second bird was largely in alternate plumage, showing strong chestnut head, breast, and back, but retained "eclipse" plumage on the flanks and belly. Both were males. Larger than Blue-winged Teal (which were nearby for comparison), but smaller than Northern Shoveler. 

Voice:

None noted.

Similar species:

Blue-winged Teal female, and male in eclipse, is grayer overall, has a smaller bill, and never has a red eye.

Photographs or tape recordings obtained?

Photos of both birds were obtained by Lane (digiscoped).

Previous experience with this species: 

I have seen Cinnamon Teal often, mostly in the western US, but in LA in January of this year (Lacassine NWR).
