I have two green, one great blue, and two kingfishers that are around in the mornings.
I've always had an abundance of bullfrogs. I was going to harvest some this year. Then my pond which had been down as much as four feet, due to draught and leak, came up 3 feet. All the weeds that had grown up during the low water, we're now under.
I thought it would help the frogs. I think I was wrong. It appears to be helping the herons. My frog population is declining.
My tadpole population though is almost at saturation.
I guess nothing will eat a tadpole. Ha

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
