That rock reminds me of a pyramid shaped one in the river here. Waterfowl like using it to stand on when the water is low. Good to see some birds from you. I had an eagle fly over me while driving yesterday, but is the first one I have seen for at least a couple months now. I suppose it is the wet weather we have had this year. Messed up the nesting sites for the herons. They have been very scarce this year. I still have not seen an egret at all either in 2018.
