FOWL

The term fowl was once used as a synonym for bird, but since around 1900 the term fowl has come to refer to woodland birds of the genus Gallus. They resemble the pheasants, but the crown of the head is generally naked and furnished with a fleshy comb, the base of the lower mandibles also bears fleshy lobes (wattles). In the wild fowl live in forests and woods, scratching around the forest floor by day and flying up into the branches to perch and to sleep at night.
