2013 Heron Observation Network Photos from the Field

To celebrate the Heron Observation Network's fifth year, I put together a collection of Photos from the Field, taken by myself, co-workers, and some very talented HERON volunteers.  Many THANKS to all the HERON volunteers who monitored colonies, and to the landowners that allowed access.  Here's to another exciting year ahead of us!  Happy 2014! http://youtu.be/GW31bH30grM

Fall Colony Visit

How Herons Handle the Heat

We’ve had some hot sultry days this summer, and if you were smart you retreated to a shady spot or went for a swim at a nearby pond.  But what about all those great blue heron nestlings that were sitting in their nests 20-100 feet up in a  tree, often in full sun?  Sure, their nest tree may be surrounded by water if it is a snag in a beaver flowage, but that water is completely inaccessible to a nestling who takes around 80 days to learn how to fly.  How do they keep cool on those 90+ degree days?  Like humans, birds rely on evaporative cooling to release heat; however, birds do not have swea

Herons Return to Colony Despite Nesting Owls

Last Wednesday I took to the field to check out a great blue heron colony that I have only seen once during an aerial survey in 2009.  Since then, a volunteer has been monitoring the colony on the ground.  I finally made personal contact with the landowners this

New York Great Blue Heron Lays An Egg
