Sea Birds Feeding as indicator of baitfish?
 

i recently saw a few close to shore feeding sessions in which many sea birds were dive bombing ocean, turning the the glassy surface into a churning, frothy spectacle. not the first i've seen, nor the largest, but one of larger feedings that close to shore.
so, my questions would be; what are they going after? and, what's going after them?

Only one way to find out

may have to!
gotta put plastic bag over the hat and NEVER look up with mouth ajar!

There have been grunion running for the last few days. If the birds were close to shore they might have been on them. Mike
