Early in Odyssey 5, Hermes, as he flies off to Calypso's island, is compared to a bird skimming the ocean in search of fish.
Later in the same book, after Odysseus builds his raft and sets out from Calypso's island, he floats along for over two weeks before he finally sees the land of Phaeacia, which is compared to a shield resting on top of the sea.
After Poseidon raises the storm and knocks Odysseus from his raft, the sea goddess Leukothea emerges from the sea "like a sea mew" (A.S. Kline's translation), gives Odysseus her veil to help keep him afloat, and then she dives into the sea "like a sea mew." Note: a sea mew is another name for a sea gull.
Several lines later, Poseidon sends a massive wave that smashes Odysseus' raft "Like a strong wind catching a pile of dry straw, scattering the stalks here and there". Odysseus still manages to straddle one of the remaining timbers "like a horseman".
