Have you ever seen a squirrel fly? Buzz Lightyear would say they do not fly, they fall with style.
The American Red Squirrel and the Chipmunk are common to Prince Edward Island. PEI is also home to the Northern Flying squirrel. Since they are nocturnal, you re not likely to have ever seen one. You may have seen a shadow passing by and thought it was a bat. See a discussion at McPhail Woods Ecological Forestry Project.
I have set up a bird feeder by my window in the hopes of catching a “noise” from a nocturnal feeder.
