I thought for sure this bird was going to need the Heimlich Maneuver, but he flew away just fine a couple minutes later. I'm guessing the pike is at least 15" long and weighs around 1 pound. A full-grown GBH should be around 6-7lbs, meaning that this meal is probably 15% of his body weight or more. Quite a hearty breakfast.
These were taken with a 100-400L that I rented for a week and this set convinced me to buy one of my own. Also got a CP filter, which I understand would reduce the glare seen especially in the first 4 shots below. Now that I have the right gear, I just need to make a point of being in the right place at the right time as often as possible. : )
