contrary to most modern depictions of Sirens. my Sirens are based off some of the earlier bird-like depictions.
some basic characteristics of my Sirens include:
- are carnivores
- nest on small, rocky islands scattered throughout the sea
- are 1.2 meters tall
- capable of flight
- have surprisingly human like faces
- have long human-like hair made out of feathers
- are slightly more intelligent than a parrot
- have parrot level mimicry, which they use with a mix of pheromones to attract their pray
- nest on small, rocky islands scattered throughout the sea
Given these characteristics, what species of bird could they have evolved from, and what evolutionary pressures would lead to them?
