Arabian Trumpeter

Bird

The Arabian Trumpeter is a breed of fancy pigeon developed over many years of selective breeding. Arabian Trumpeters, along with other varieties of domesticated pigeons, are all descendants from the Rock Pigeon (Columba livia). There are several breeds of trumpeter pigeons which are known for their vocal cooing which sounds similar to laughter or trumpeting. The breeds with this ability are collectively known as "voice" pigeons.
