I would feel bad if I knew someone that had an accident with a heron. And my customers would remain blissfully ignorant. But please do not take me for kill em all let God sort them out Frog. I go out of my way to take care of species I see at my ponds, even those I don't want. For emample Garter snakes. They are super frog killers. But not that difficult to catch. I have a critter container, normally carry it in my truck just in case. I catch them, get all stinky, and relocate them to a nature reserve creek area by my home.
Several times this season while mowing cattails I have come across active bird nests. Mainly coots and blackbirds. I actually leave them completely alone. Last week I was cutting back cattails and my son said there is a nest with a baby bird in it. We cut around it and left the stand and nest there. And I am under contract to cut this stuff down. I just explain to the customer and normally they are appreciative as long as I come back when the nest is empty and do my job.
The geese are another issue. Dam poop machines. Really bad. Even if I bottle rocket or popper them away I usually see them back later in the day or next week. If I could capture and relocate to a safe haven any animal or bird I would. Well, maybe not muskrats.
