Scarleteen Eagle

Scarleteen Eagle
The scarleteen eagle is one of the most deadly animals on the planet. It looks like an ordinary eagle except for the blue patches on its wings. If you touch its feathers, poison will spread through the victim's body. If the poison doesn't kill the victim, it will paralyze or open wounds in usually fatal places, like the chest or the neck. Chances of survival are slim. The Scarleteen Eagle will only attack Ravenclaw students.

The Cure
The only cure for a victim is the juice of a Scarleteen rose, which is only found around a Scarleteen Eagle's nest.
