bluegills are well known eye peckers yawl , any minner guy will tell you they are a nightmare on live bait.
not sure if its a kill thing but to be for sure sure they love to peck heads on minnow type items .
might just be they like the taste of eyeballs ? I seen a many ketched before on JUST fish eye balls …..
and there you have it …..
KABOOM is the word
