Five or 6 eggs are usually layed. The male then abandons the female, who must incubate and care for the young alone. Incubation lasts for about 23 days, during which time the female spends almost three-fourths of her time on the nest, while the rest is spent in feeding and comfort movements. Once hatched, the Teal ducklings are more sensitive to cold than other duck species, and the mother must protect them from extreme cold through brooding. She also leads them to water and food and protects them from predators by using techniques of distraction.
Teals are rapid, agile flyers.
They are the only duck known to scratch while in flight. They do not dive for food, but have been seen diving to escape predators. Males exhibit distinctive whistles, while females typically vocalize through a series of quacks. The sleeping and preening behaviors of the Teal strongly resemble other duck species. For example, they sleep standing up with their bill turned into their back feathers.
