Creature designs for various birdlike monsters/creatures in our setting.
The Siren and the Harpy.
Sirens are the more humanoid of the two species. Having heads and faces that closely resemble a human woman, though affixed with a permanent grim and a sharp beak rather than teeth. They are territorial apex predators spread across many of the endless coasts and islands of the Great Archipelago and are very adapt at using their innate magical ability to their advantage. Their siren's song is used to attract prey, intimidate, confuse and many other things. Sailors who've come into contact with the creatures report that the particular voice of the siren's song sounds like their first love to them.
Harpies are quite different. Much less humanlike in both appearance and intellect, harpies are a common type of birdlike creature found all over the great archipelago, the common coastal harpy is a sight almost all inhabitants of the continent are familiar with. While the harpy generally lacks advanced magical abilities, their screech can be loud enough to rupture eardrums and is said to resemble the pitched scream of a woman or child. Mostly they are just really annoying and often pester sailors and people traversing through their territory.
