A unique sound, not what you would expect, but one you will not forget.
The call is deep and raspy, almost a long drawn out cough.
The Great Blue leans back and stands up tall.
Most calls are reserved for their mates. Early in the year calling out for them to return to a nest, and later when a mate needs the other to return.
When out photographing you will hear them from a long ways. For me the call tells me to walk a little faster, the Herons are on the move.
