Lark
The  lark is a very popular animal, appearing in literature, song,  mythology, and even religion.  Though we write of the lark very often,  the only true North American lark is the horned lark, which is  named for its black stripes beneath its eyes.  The meadowlark also  inhabits North America, though technically, the meadowlark is more  closely related to the starling.  This doesn’t stop us from relating the  meadowlark to the true lark, 
however.
Larks  are known for their melodious singing.  They also sing while they are  flying, unlike most other birds, who only sing when perched.  This  indicates cheerfulness and reminds us to find joy in our own lives.   Larks are also very good mimics of other birds’ songs.  Perhaps this  tunefulness is the reason that larks are messengers in religion and  mythology.  In Lakota/Dakota myth, larks were the messengers of the god  Itokaga (Okaga).  Itokaga was the representation of the south wind.   South is the direction of the sun and the bringer of warmth, light, and  life.  Therefore the meadowlark is associated with all of these things,  in addition to women’s medicine, which encompasses beauty, fidelity,  happy marriage, and fertility.  Seeing a meadowlark is good news for the  viewer, because the lark brings abundance and impending harvest.
Larks  have a crescent shape across their breasts.  The crescent shape often  signifies lunar qualities, and the moon is often linked with the concept  of self.  Therefore the lark reflects the inward journey that’s often  associated with self-discovery.  This goes hand in hand with their  singing, something that, for humans, is often considered a private  activity and a deep reflection of inner self.  Lark encourages us to  explore our inner selves and sing out loud.
