hyacinth macaw, but I don't think Gabby's species is one of them. Amazona ochrecephala oratrix (Gabby's species) is from the Yucutan Peninsula in Mexico. The range of the hyacinth is concentrated in Brazil and Bolivia.
I actually thought about hyacinth macaws while Gabby was killing the towel. I'm very glad it wasn't a hyacinth macaw for Gabby's sake. The hyacinth has the most powerful beak of all birds!
