This Grey Heron was taking a break on a pole in the Sundays River at Colchester and wasn’t really bothered when we cruised past it on the Sundays River Ferry. The Grey Heron (Ardea cinerea), is a wading bird of the heron family Ardeidae and grows to about one meter in height with a wingspan of between 1,5 and 2 meters. It normally feeds in shallow water, catching fish, frogs and insects with its long bill. Herons will also take small mammals like mice and rats as well as reptiles. It will often wait motionless for prey, or slowly stalk its victim.
