Mother and child, adult osprey have yellow eyes, while the juveniles have a copper colored eye.
That leaves me to this morning. On my way to work I spotted a pair of redtails getting harassed by what I believe were European Starlings. This went on and on for 20 minutes. Would have stayed longer but had to get to work!
Im field testing a new lens, a F2.8 400mm with a 1.4 teleconverter. Its amazing how heavy and bulky it is. I am on day 2 of 7 that I will be using this lens. While the benefits of huge glass are very apparent in this test I did below.
On the left is my everyday wildlife lens, the middle is 'my' new one, also a 400mm, far right is the new one with a 1.4x magnification teleconverter.
