The term CATTLE BIRD is composed of five words: EGRET (5 letters), MOO (3 letters), STEER (5 letters), PROD (4 letters), and KINE (4 letters). An EGRET is a type of white heron, and MOO is the sound made by cattle. A STEER is a castrated male bovine, and PROD is an action of pushing or poking. KINE is an archaic word for cattle. Therefore, the term CATTLE BIRD can be interpreted as a combination of animals and actions related to cattle.
