Though the peacock is well-regarded for its lustrous feathers and its regal appearance – to the point that it was declared the national bird of India – many people are genuinely scared of peafowl. Ornithophobia is the fear of birds in general, but enough people have experienced feelings of terror and panic in the presence of peacocks that the term "pavophobia" has entered the lexicon. And for good reason: Peafowl can be aggressive birds, and peacocks (male peafowl, known for their patterned tail feathers) even more so.
