question about fishing under the birds

[Marque]

I find fishing birds to be a losing proposition 75% of the time. This time of year they are mostly on gaff tops and sand trout. I find the groups of 5 to 10 birds in a tight formation the most productive. A group of 20 spread out and hovering is going to be small fish and will most likely be moving to fast to keep up with on the trolling motor. I try to get in behind them because I think that the feeding fish are basically facing the same way as the feeding birds. I like to throw tsunami type swim baits and work them with the current. Birds and fish usual feed facing into the current. I have approached them from upwind/current before and not had a bite until I drifted down current enough to present the bait with the current. I find the bigger fish corral the school of bait a lot tighter than the little ones. If you get on a school of decent trout under birds you can almost anchor because the birds won't move far.
