The Seagull was taken with a flash on a cloudy day in Florida with my Canon Rebel ESO camera. The Eagle shot was taken in Florida. He was a captive bird on a perch, which I was able to get close to. This was a real treat for me.
On the other hand, the Airplanes shots were taken at the March ARB, in California with my 400 IS lens. That lens has been a “God Sent” to me for getting close to my subjects and to help with stabilizing movements. It was difficult to use my tripod so the airplane photos were hand-held.
