Great Blue Herons are a common sight in marshes and waterways throughout the US and southern Canada. They are the largest of all the New World Herons and Egrets, and are often misidentified as Cranes because of their dark color and large size. Herons and Egrets nest in colonies and build nests of sticks in low trees near the water. During the breeding season, adult Great Blue Herons grow wispy head plumes, which can be seen blowing in the wind on this bird. This one was photographed at Brigantine NWR, New Jersey, USA. Photo taken with a Nikkor 300mm ED f4.5 lens on Kodachrome 200 film. (Date: April 1986)
