Final answer:
Sophocles does not consistently use bird metaphors as conveyers of messages from the gods, and therefore the answer is false. Sophoclean literature is complex and cannot be reduced to simple metaphors or singular messages.
Step-by-step explanation:
The question pertains to the use of bird metaphors in the works of Sophocles, specifically whether he uses them to emphasize their importance as messengers of the gods. While Sophocles does employ various literary devices to enrich his plays, this question seems to suggest a more direct and literal interpretation of birds as divine messengers which is not universally present across his works. Thus, the answer to the question would be false.
It is important to understand that literature, and especially works as nuanced as those of Sophocles, seldom convey a singular, simple message. Literary analysis often uncovers a wide array of themes and messages that go beyond simplified morals or direct messages as one would find in Aesop's Fables. In Sophocles' plays, the complexity of human life and existential questions are explored, rather than sending clear-cut messages via avian metaphors or otherwise.
