I am so sorry for your traumatic loss. It sounds like a Hawk, perhaps a Coopers Hawk. They attack and poke out the eyes of their victims. We have them here and I have to watch for my Chihuahuas also. If you have a hawk in the area it is not safe to put any pet birds outdoors since birds are prey to Hawks. So sorry about your bird.


Although hawks do not have red on them light refraction can display colors in a bird that are not present.

It may also have been a younger Hawk looking for an easy meal.
