The brown creepers are small birds, about 5 1/2 inches. Starting at the base of a tree the brown creeper slowly creeps up to the top, using its tail to brace its self against the bark. The creeper uses its long down curved bill to peck and probe at the bark to find food. It will eat; all types of insects, weevils, beetles, ants, spiders, and at times insect eggs that are hidden in the bark. Sometimes they will eat; corn, sunflower seeds, suet, grass seeds, and etc.
When they get near the top of the tree, they will fly down to the bottom of another tree, or the same tree, and start all over again, looking for food. It is rare if the creeper climbs downward, once it is near the top.
The colors and markings on a creeper are about the same colors on barks on trees. The bird blends in well with the tree bark, making it hard to see and find. If a creeper hears or sees a predator, it will spread it wings and press itself against the bark of a tree, and freeze until the predator has moved away.
