I was driving past a local golf course (has a lot of mature oak trees) and I saw of all things a black squirrel. For as much as I hate squirrels, this was a pretty thing, it was totally black. I didn't know they existed! About a quarter a mile down the road and there was another one. I looked around the web and it seems that the black squirrel simply has a more melanin than the grey squirrel, and the all white is an albino with no melanin. The black is rare, but the albino is rarer.
Anyone ever see a black squirrel? If you have, please forgive my childish enthusiasm, I just wanted to share this cool sighting.
