Yosemite is home to a variety of animals, out of which
deer are the most commonly seen by visitors. They tend to hang out in
meadows early in the morning and in the late afternoon or evening. I was
able to see deer on all my visits to Yosemite. As for other wildlife, I
didn't see any. My guess is you'll be more lucky if you find a quiet spot
during early morning or early evening; you may catch a glimpse of wildlife
in action. Although you are adviced to lock every piece of food for fear of
bears, I don't think bears are easy to find in Yosemite. They tend to avoid
people, so you are not likely to see them in developed areas (I would still
advice that you lock the food). Instead, you will probably be able to see
lots of birds, especially in meadows, along the rivers, and in forests
adjacent to meadows.
