That's a good point, I bet you're right. Where there's a lot of competition for food it would make sense for them to eat on the fly.
It's interesting to walk around under known roost trees here when the numbers drop. There are many dead fish dropped when the initial catcher/eater is confronted on the roost and drops his/her catch either in an attempt to defend themselves or just to avoid the confrontation.
I try to stay out from under trees with these things around, in general
Great shots Eric and congrats.
