Light pollution affects animals by changing the natural darkness they use to navigate, feed, rest, avoid predators, reproduce, and time seasonal behavior. Artificial light at night can pull migrating birds toward cities, draw insects into dangerous places, disrupt sea turtle hatchlings on beaches, change how bats and mammals use habitat, and alter the balance between … Read more
Animals that live in cities are not just strays, pests, or occasional visitors. Many are wild species that have learned to use streets, parks, rooftops, storm drains, gardens, bridges, and building ledges as part of their habitat. Some eat a wide range of foods. Some hide in small spaces. Some are active at night when … Read more
Urban wildlife is made up of wild animals that live in, move through, or regularly use cities and suburbs.

These signals can say a lot without a sound: who has been in an area, whether an animal is ready to mate, where food may be found, whether danger is nearby, and sometimes which group … Read more
Animal sounds can mean many different things, but they are not simple word-for-word translations. A bird song may help defend a nesting territory. A frog call may advertise a male during breeding season. A wolf howl may keep a pack connected across distance. A whale song, click, whistle, or pulse may carry social, feeding, mating, … Read more
Animals communicate by sending signals that other animals can detect and use. A signal may be a sound, smell, color, posture, movement, touch, vibration, electrical discharge, or a combination of several cues at once. The meaning is not always as simple as a human word. A bark, flash, scent mark, or courtship dance usually makes … Read more
Animal communication is the way animals send and receive information through signals. Those signals can be sounds, scents, colors, movements, touches, vibrations, electric pulses, or combinations of several at once. A wolf howl, a bobcat scent mark, a bee dance, a beaver tail slap, and the low electric pulses of an electric eel all solve … Read more
