Not many zoos can show the northern screamer.

In contrast, the Northern Screamer is relatively rare and therefore considered near threatened.

Among the more remarkable inhabitants of river islands and large beaches is the Northern Screamer, which can be seen in the park throughout the year.

There are three screamer species, the other two being the Southern Screamer and the Northern Screamer in the genus Chauna.

The Northern Screamer (Chauna chavaria), also known as the Black-necked Screamer, is a large species of bird in the small family Anhimidae, the screamers.
