While chances of spotting wildlife are plentiful, a few key tips can help you get the most out of your Yosemite wildlife viewing experience.
Avoid groups of people. Most animals are like introverted people and are easily frightened by large crowds.
Attempt to blend in. The color of your clothing (darker colors blend in better) and your overall movement can help conceal you in your surroundings, making wildlife less afraid of your proximity.
Go slow. If you see a large animal like a deer or elk, stay calm and don't make any sudden movements that might alarm them. If you want a better look at a smaller animal that has gone to ground, pick a comfortable spot and wait. If you're patient, they'll probably peek their head out to see what you're up to.
The best way to find a good wildlife watching spot is to look for evidence of where the animals hang out. Dens, trails in the grass, holes where something has been buried.
