the monster manual: perytons [implied general] hunt humanoids and tear out their hearts
the monster manual: female perytons [clear specific] need to eat a freshly-killed humanoid heart as part of their reproductive cycle
the monster manual: when attacking a humanoid, a peryton [again implied general] is single-minded and relentless, stalking lost prey until it finds it again
me, taking careful notes: perytons... must... eat a humanoid heart... to become female... and lay eggs
