Perches serve many functions for birds. They provide a place to eat, drink, sleep, rest, exercise and play. A perch provides lots of exercise, giving your bird a reason to fly and jump back and forth between perches. Some perches are made of cement and some are sand-coated, which is good for keeping nails and beaks trimmed. There are wooden perches and cotton rope, both help to satisfy a bird’s natural chewing instincts.
