A few weeks ago, I found out that there was a Brown Booby in Arkansas. So I made the 5.5 hour drive to see it since I felt like it was a once in a lifetime chance to see this bird this close to home. The local fisherman that found it was giving boat rides to see it much closer. As we were walking to the bank, the boat was leaving with one of our Oklahoma bird friends. We could see it from the boat ramp, but it was about 1/4 mile away. I wish I could have gotten some close flying shots but when it was our turn in the boat, it stayed perched the entire time.
I was using a 7D mark II, Canon 500mm v1 and a Canon 1.4x teleconverter v3.
