I have never seen an article or study done on how bats differentiate fresh water sources as opposed to solid ground. I am sure that water makes a different "echo" than ground to the bats, I would love to see a link to something of this nature.
My lifetime goal is to have a few acres of land and a 1 to 2 acre fishing pond, and also have bat houses hung around it. But the pond would be a new "dig" and if there isn't a former year-round water source within 1/4 mile, how are the bats going to find my new pond and take up residence beside it? Do they sometimes echolocate towards the ground in new areas?
Any response or speculations would be greatly appreciated!
Nate
