Breeding and Nesting

Common Teal: These teals usually arrive at the breeding grounds with pair bonds formed. Six to eighteen creamy white, light olive or buff eggs are laid in a down-lined ground depression filled with grasses, twigs and leaves, located in meadows, open woodlands or brush, often several hundred yards from water. Incubation ranges from 20 to 24 days and is carried out by the female.

Foraging and Feeding

Common Teal: These teals have a broad diet including the seeds of sedges, grasses and aquatic vegetation, aquatic insects and larvae, mollusks and crustaceans. They are opportunistic foragers, feeding on animals or plants in high abundance. Typically they feed in shallow water, near shorelines and on mudflats.

Vocalization

Common Teal: Male emits melodious whistling, described as "prip-prip" or "KRICK-et" as well as burp calls. Females produce shorter, harsh "quack" calls.
