In the first place, I did not know that cormorants hunt in packs.
At Brays Bayou in Houston, TX this morning I witnessed a flock of maybe 40 in an absolute feeding frenzy, working their way downstream in a tight grouping and spreading terror, no doubt, throughout the fish community below. I captured some surface turmoil at one point and later discovered this huge fish had burst into the air to the amazement of everyone, including the cormorants.
Anyway, I had no idea there were fish this big in the local bayous. What do I know? Next to nothing, apparently.
