As I was scanning a pond last week for activity at Occoquan Bay National Wildlife Refuge, I spotted this structure. Its relatively large size initially made me think that it might be a beaver lodge, but after more closely examining the construction materials, I have concluded that it is more likely to be a muskrat habitation.
Unlike beavers that use large sticks and logs and a lot of mud, muskrats (Ondatra zibethicus) mostly use cattails and other reeds to form mounds that permit them to dry out and get some air. Occasionally beavers and muskrats will share a beaver lodge, but I am pretty sure that is not the case here. The fragile nature of this kind of muskrat house makes it vulnerable to predators if the pond freezes over and allows access to foxes or coyotes, both of which inhabit this wildlife refuge.

Last Sunday, this masterpiece of beaux-arts architecture, le Grand Palais was open to the public for a few hours and I rushed in along with fantastic photographer, and now street sketch artist, Mike Powell, on one of his last days in Paris, in order to snap a little of the light under the glass.
