Boston's Emerald Necklace
Great Blue Herons
by Stephen Baird
Great Blue Heron - Ardea herodias
Great Blue Herons are common in the Emerald Necklace and can be seen wading and hunting for fish, frogs and mice near or in the water at Franklin Park, Forest Hills Cemetery, Arnold Arboretum, Jamaica Pond, Olmsted Park and the Muddy River. Herons are large majestic birds which have inspired stories, myths and legends since ancient Egypt. See references below.
Adult birds grow to 3-4 feet in size with a 5-6 foot wingspan and weigh 5-7 pounds. Males are larger than the female.
Song is harsh low “Cronk” when disturbed. They have many other calls. See references below.
Life span is 15 years in the wild. About seventy percent of young birds die in the first year. Oldest known Great Blue Heron was 23 years old.
Most active at dusk and dawn, but also hunts during the day and at night.

This Great Blue Heron caught a very big hornpout catfish in Leverett Pond in Olmsted Park. I watched it as it repeatedly speared the fish with its razor sharp bill and attempted to swallow the fish whole head first for over an hour. Hornpout have very sharp spiney fins. A dangerous meal for a Great Blue Heron. Great Blue Herons have died because they swallowed prey that was to large for their long S shaped necks and internal intestinal systems.

Great Blue Herons conduct courtship during March by exchanging nest branches, clicking beaks and body movements. Usually lay 2-6 blueish eggs in colonies of 5-300 nests in tall trees called herones. The incubation by both male and female lasts around 30 days and eggs hatch during April and May. Young herons fledge in 8 weeks. Great Blue Herons mate with different partners each year.
Solitary hunters and primarily eat fish, frogs and reptiles, but also will eat insects, mice, rats and birds.
Great Blue Herons will migrate south to open water during the winter. Several hardy individual Great Blue Herons have spent the entire winter in the Emerald Necklace Parks.
Fun Facts:

Kills prey by using long sharp beak as a spear
Regurgitates foods for young
Can fly 20-30 miles per hour
“Grande Héron ” and “Garza morena” are the French and Spanish names for Great Blue Herons
