Ardea herodias
The great blue heron usually breeds in colonies, in trees close to lakes or other wetlands. Often such colonies include only Great Blue Herons, sometimes they nest alongside other species of herons. These groups are called heronry (a more specific term than "rookery"). The size of these colonies may be large, ranging between 5–500 nests per colony, with an average of approximately 160 nests per colony. Great Blue Herons build a bulky stick nest, and the female lays three to six pale blue eggs. One brood is raised each year. If the nest is abandoned or destroyed, the female may lay a replacement clutch. Reproduction is negatively affected by human disturbance, particularly during the beginning of nesting. Repeated human intrusion into nesting areas often results in nest failure, with abandonment of eggs or chicks.

Thanks for the interesting information and lovely pictures.
I agree Karen, early to mid spring and early fall are my two favorite times of year. The temperature is at a perfect place and the wildlife is absolutely fabulous.
Thanks Karen i agree is awesome!
Gerardo, there were many herons on the nests & also soaring overhead! It really was an awesome sight!
Apple, today was really springlike in middle Tennessee. I love this time of year - such a lovely few weeks between the cold & the unbearable heat & humidity!
