A White-footed Mouse spent at least an hour on the frozen ice of The Lake running around in circles on Wednesday, in Central Park. There are a few recordings of mice doing the same thing in other locations on YouTube. I wonder if in the below freezing temperatures on Wednesday had the mouse doing its best to raise its body temperature. Or it could just be pre-Winter Olympics hype sponsored by NBC/Comcast.

Update: Based on discussions on my Facebook page, it could be a neurological problem due to a raccoon roundworm infection. A primer on Baylisascaris procyonis has been written by the USGS: https://pubs.usgs.gov/circ/1412/cir1412.pdf
