FUN FACTS

1. Cape teal are one of the few species of dabbling ducks that actually dive. They are capable of swimming underwater with their wings closed like other true diving ducks. Normally, dabbling ducks dive with their wings open.
2. These ducks have tooth like serrations around their bill, which scientists think means filter feeding is important to this species.
3. Teals are not very vocal, but males do emit a high-pitched whistle and the female responds with a nasal quack.
4. Cape teals are known to perform what is referred to as 'nod swimming' during courtship. It is a rapid scoot over the water surface in a semi-circle with the wings positioned so that the speculum is showing. However, during such a dance, at no time does the duck ever actually nod.
5. Many ducks have high mortality rates during the egg and duckling stage, but because both parents raise the teal ducklings, fewer offspring die. Cape teal are good parents and will often aggressively defend their young against larger birds.

ECOLOGY AND CONSERVATION

Cape teal are not endangered. In fact, the population is most likely increasing due to new dams, reservoirs, and irrigation projects. They are commonly hunted for food by both animals and humans.
