Use field guides. Field guides can tell you the best times of year for viewing, habitats, behaviors, and identification to use in the field. Enjoy wildlife at a distance. Refrain from touching, feeding, or getting too close to animals. Some birds will abandon their nests if they are threatened.
Animals can be dangerous when cornered.
Young animals that appear orphaned usually have parents waiting in the shadows. Allow yourself enough time in the field. Settle in and enjoy the wildlife that comes to you.
