Bird shelters are structures designed to provide a safe and comfortable environment for birds. The two most common types of bird shelters are dovecotes and cotes. A dovecote is a structure specifically designed to house doves and pigeons, while a COTE is a more general term used to describe any type of shelter for birds. Both dovecotes and cotes provide protection from the elements and predators, as well as a place for birds to nest and raise their young.
