ardea herodias

Great Blue Herons in B.C. are feeling the pressure of human population growth. Herons are very sensitive to activity near their nests, in particular early in the nesting season. Though they can get used to day-to-day human activity, novel noises (e.g. sudden blasts of horns or chain saws) can cause the birds leave their nests, making the young vulnerable to predators such as eagles. If the noise persists, it’s possible that colonies will abandon their site completely.
