What are the Herons natural predators?
Herons are susceptible to disturbance from Bald Eagles that prey on chicks and adults in the colonies. A nesting heron study conducted in 1999 in the Georgia Basin concluded that Bald Eagles targeting heron eggs or young were responsible for the abandonment of 13 of 31 colonies (Vennesland, 2000). However, humans might have been ultimately responsible by creating a fragmented landscape that allowed eagles easy access to herons and their nests.
