About These Birds
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
Australian Little Bittern
The Australian Little Bittern is a small heron found in freshwater wetlands and reed beds across Australia and New Guinea. Weighing about 89.5g with a wingspan of 26.3cm, it is a cryptically streaked bird that clings vertically to reed stems to avoid detection. It feeds on small fish, frogs, and aquatic insects.
