"I canoed Eagle Lake this morning. I found 6 loons, including the banded loon in image 4389 ( the bird in the background with a green band on the left leg). The banded loon was banded as a juvenile in 2003 on Putnam Pd. He hung out at Gooseneck Pd. in the summer of 2010, and was not seen last year. I was thrilled to have him fly in and whiz right past my ear and land among a group of loons I was watching. He has an orange band on his right leg, and a green band (with a stripe on the green that you will probably never see) and a silver band on his left leg. If you see him or any bands on loons or eagles, please send me an email.
I also watched an osprey catch two fish, and after the second fish it was pursued by a mature bald eagle, but it out-maneuvered the eagle and got away with its prize. A raven flew by carrying a hapless nestling bird to feed to its own squawking chicks. So it is likely that you have an osprey and raven nest nearby, and possibly an eagle nest. Let me know if you see any signs of loons nesting. They did not demonstrate territorial behavior while I was there. They all seemed to get along, like non-breeders.
Also, the causeway bridge is full of barn swallow nests underneath and it is cool to watch the swallows and see the nests when you canoe under it. A great blue heron let me paddle right up to him on the big, inhabited island. It was a great morning. Enjoy your Eagle Lake wildlife."
