I wasn't really bothered by these things till OP posted and I got to researching about them. They only eat a lb of fish a day. They only stay for 90 days and then they migrate on. Those numbers sound small.

Some ecosystems(lakes) in Texas by those numbers lose 9 million lbs of fish during their stay. I'm mad too.

Hey Ketch take a look at these. They only relocate the birds to other lakes and it may not help you considering the area you cover at times. But it's a start.Name:  Screenshot_20210417-215015.jpg
