Their small size and twisting turning flight gives the illusion of great speed. The small, compact flocks commonly fly low over the marshes, and often take the hunter by suprise. They are more vocal than most ducks - their high-pitched peeping and nasal quacking is commonly heard in spring and to a lesser extent in fall.
These teal are among the first ducks to migrate each fall, and one of the last in the spring.
