Ornithophobia
Ornithophobia is a term that I’m curious if you’re familiar with. It’s possible that it isn’t, but there’s no issue if you haven’t tried it yet. In its most basic form, ornithophobia refers to a fear of birds, which is typically brought on by a negative experience with a bird at some point in a person’s life.
It’s possible that you’re perplexed as to why people would be afraid of creatures that appear to be so pure and lovely. Your point is well taken, with the possible exception of the scenario in which the bird is approximately 2 meters tall, towering over you, and putting its beak in your face.
