I have one Kingfisher that usually hangs out at the pond from spring to fall. I think they are gorgeous and so fun to watch. I marvel at their skill in spotting and catching fish. It seems the one by me mostly takes smaller minnows for an occasional meal and I have no problems with that. They are loud, chatter like crazy but that also helps me know when he/she is back at the pond again which is nice to know.

There must be a nest near by I have never seen a 2nd adult or young kingfisher around our pond.

This year the kingfisher appears to like to perch on my mallard nest tube which gives it a closer vantage point to the water.

I'd say enjoy that you have 3-4 of them.
