they eat more than just baitfish, they will even attack Comorants. On the Red River at Lockport, these birds outnumber the rocks on shore. they swim around in pods and attack schools of good sized goldeye, Saugers, Drum, White Bass, etc.

I have even noticed now they are on the North Saskatchewan River in Fort Saskatchewan.

First time i ever seen one was on Beaver Lake by Lac La Biche years ago.

I wish nothing but pure evil on them
