Species of the Week: Great Blue Heron

The Great Blue Heron can measure up to 1.4 m in height and weighs between 2 and 3 kg. They are expert fishers and hunters, that tend to be solitary except during the mating season. They nest in trees, and lay several eggs at a time. Their lifespan is between 15-20 years.

Their long sharp beak is used to spear a variety of prey, including fish, snails, insects, snakes, frogs, salamanders, rodents and even small birds. They hunt alone, predominantly around dawn and dusk, and breed in large colonies. Despite this group protection, predators ensure that only about a third of hatchlings survive the first year.
