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.
Bermuda Night Heron
The Bermuda Night Heron was an extinct night heron endemic to Bermuda, known only from subfossil remains recovered from cave deposits. It likely fed on crabs and marine invertebrates in the island's intertidal zones, as its name suggests. It became extinct following the arrival of European settlers and the introduction of predatory mammals.
