We're wondering if it's the same young squirrel that was treated for injuries by Toronto Animal Services and then released back in to the park in September 2012....? The Toronto Star did an article at the time.
The Toronto Star's Margaret Bream also did an article called Wild in the City: Encountering the Mythic White Squirre which gives some good information about what they are. It explains that what we have at Trinity Bellwoods Park is an albino eastern grey squirrel (Sciuris carolinensis) rather than a white morph — the name biologists give to a local variety of a particular species that appears different from the norm. Toronto’s black squirrels, for example, are a black morph of the eastern grey squirrel.
There is more than one in our park so there are sure to continue to be sightings -- but, sadly, fewer.
