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.
Great Tit
The great tit is the largest European tit and one of the most studied wild birds in the world. Research at Wytham Woods in Oxford has monitored great tit populations since the 1940s, contributing enormously to ecology and evolution. These innovative birds famously learned to open milk bottle tops in 20th-century Britain.
