I have often seen Great Blue Herons sitting in the fields west of the main dike at Farmington Bay during the winter, all crouched down and looking very cold. Last Friday while I was out there taking pictures I watched them in action and found the real reason they are huddled out in those fields. I saw one in his ready to pounce stance so I stopped and watched, he stood motionless for a long time then with lightening speed he struck and came up with a very chubby and delicious looking Vole. Birds survive because they learn to adapt to their environment. While watching I took pictures of the whole event and here are a few.
Now that the ponds are all frozen over the Blue Herons are hunting with the Harriers, Kestrels and Red-tails but with their own unique and deadly method.
