Facilitating the protection and restoration of species and ecosystems at risk on BC’s South Coast
Height: 60 cm, Wingspan 1.5 m. Both sexes are similar. Adult Great Blue Heron are tall, long-legged wading birds with a sinuous neck held in an “S” curve at rest and in flight. The long thick bill is yellow and black, the head and face are white. In mature birds, plumage is a steel blue-grey with dark blue-grey flight and tail feathers. As birds mature a distinctive black plume extends from above the eye to beyond the back of head and a bib of long trailing plumes on the chest and scapula area become more pronounced. Juveniles are grey-brown on the back and upper wing plumage and lack the black eyebrow and adult head and bib plumes.
