Fun FactThe Great Blue Heron is relatively quiet compared to other members of its family. The heron releases a soft "kraak" when it is disturbed and in flight. Other calls of the heron include a "fraunk" when the bird is disturbed near its nest, and an "ar" when the heron is greeting other members of its species. |
