It was heavily overcast and even drizzling a bit. I used the monopod and here is a 100% crop of the Bald Eagle nest. I was cropping the Sigma lens shots at 1300 pixels wide while this one is 900 pixels wide. With better lighting conditions, I think the Canon lens out performs the Sigma.

An advantage of the 55-250mm focal length range is that you can get other types of shots while you wait for something to happen with the Eagles. Here are some three file HDR shots on the trails along the way. I bracketed +/- 1.5 stops. Exposure info is for the normally exposed file.
|55mm, f/8, 1/1500 sec., ISO 800|
|200mm, f/8, 1/180 sec., ISO 400|
|152mm, f/5.6, 1/90 sec., ISO 400|
Should have used f/8 for more depth of field

And on Peebles Island there's always the deer you see on the way out.
