Up here, My wife, son and I tend to do a lot of lake fishing for cats, even tho the Red River is notoriously famous. I just like lake fishing. We have some favorite large shore to deep water sand bar stretches that drop off into deeper water.Normally we watch for the above mentioned birds..if they're present or how far out they are and how fast they're moving in towards shore. We think that they're following the bait fish. So we can almost predict whether it's going to be a good lake day of fishing or a poor one just by watching the birds. If the birds are moving in closer as the day streches out into evening we just stay shore fishing. If the birds are a distance out and not moving in we take the boat out. Works for us..just thought someone else might want to try this. Have fun.
