Thanks for your comments,
You're right it's not easy to focus on the eye of a bird flying at some speed.

Especially with a manually focusing lens. I have more luck with auto focus lenses...but I must say, I think you did an excellent job.
I use my 55-300 a lot for birds and I usually set the F stop around F 10 in bright sunlight...as birds tend to fly in and out of the depth of field...particularly when that DOF is so narrow at F 2.8- 3.5 or so. I like taking pictures of big slow moving birds like American White Pelicans...but before I attempted getting pics of them...I found a bench near a bird feeder and spent a fair amount of time trying to get pixs of Chickadees. They're small, fast flying and erratic in direction. Once I got some good experience getting pix of them, bigger, slow moving birds were easier. But I'm still no expert.
