Busy Beavers at Cooper Park

When Scott and I visited Cooper Park yesterday, there were many noisy Mallards out on the water where the beaver pond used to be (before last spring's high floods destroyed the dams). When I got closer I could see a large beaver on the shore, working on some branches, and then slowly moving into the water where he worked for a very long time weaving his branches into the new beaver dam that the beavers are constructing on the upside of the stream entering the marsh. He meandered back towards a small tree and took it down in a few concise bites and then drug it back to the dam where he worked again to weave it into the dam. A friend was helping from the water.
