Pond Boss Forums INTRO Questions & Observations What critter would do this?

Maybe yes, maybe no (the mink), but the dropping water levels might also have something to do with it. The 'rats would have to dig new homes because they would be too exposed with the lower water levels.

I know it may go against your plan, but if I was in your shoes I would also let him target 'coon. They play havoc with nesting birds, not only cavity nesters, but also the ground nesters. And because they swim readily, having an island for the ground nesters only offers slightly more security than a nest on land (it will help keep the opossums and skunks away).

Having another animal to target might help him out due to the low 'rat population. Fur prices are supposed to be up this year, so you might not have to offer a bounty on them like you did with the 'rats. Towards the end of last year, 'rats (XL size) were bringing $7-$8 in the round (not skinned) in this area.
