Ok, so this happened two days ago. I was in my kitchen, cleaning up and puttering about after a weekend of both children visiting/living at home (so fun). I heard a very loud thunk, as if a bird had flown into my window, but louder. I live on the river, up a fairly steep bank, and the view of my decks and the marsh beyond is visible through four big picture windows and one sliding glass door. Frequently birds try to enter the reflected world and bang into the glass, mostly flying away, sometimes not.
This time I looked out and saw - what? - some mammal, not much bigger than a squirrel, with a pointy rodent face and wet, dark fur. Muskrat? No - the tail was flat and wide. A beaver?? It was sitting on my windowsill, looking around. What? I started talking to it in an accusatory tone. I have had snakes and mice and chipmunks and bats and even a squirrel inside my house but never a beaver so close! I did not even think they were in the Kalamazoo River. "What are you doing here? Why are you at my window? You cannot come in!" It shook its head and ran under the deck steps. I felt thankful that it had not crashed through the screen at my open slider.
My hope is that it made it back to its parents and the water in fairly good shape. I am happy to know this ecosystem is healthy enough to house beavers. Another score for mother nature!
