Peacocks are surprizingly common in Europe. Charlemagne specified in a Capitulary https://www.gardenvisit.com/history_theory/garden_landscape_design_articles/europe/capitulary_of_charlemagne that each of his manors should have a peacock 'for ornament' and so grand houses quite often have them. I therefore asserted that a magic peacock could well have been brought up in a Covenant.
In myth Peacocks are sometimes associated with guarding the Tree of Knowledge and also eat serpents hence the sense Holiness and Unholiness. The Eye things are I hope obvious....
