|Real Name:||Stymphalian Birds|

|First appearance:||Cronus' Flying Circus|
The Stymphalian birds are enormous hawk-like birds with brass claws and sharp metallic feathers, originally defeated by Hercules for one of his Labours. They reside in a dark cave with luminous trees, where they have nests. While fierce and dangerous and highly resistant to most weaponry, they are not very intelligent and are easily attracted to shiny reflective objects, like Neil's three panel mirror. The parents flew into Cronus's escape tunnel and their only offspring was under Chiron's care. Another type of Stymphalian bird with feathery wings and a black body also attacked Theresa before she was rescued by Hermes.
Stymphalian birds are man-eating birds with beaks of bronze and sharp metallic feathers they could launch at their victims, and were pets of Ares, the God of war.
Beridding a swamp of Stymphalian birds was the sixth labour of Heracles.
