n. Fear of birds.
Wikipedia
Ornithophobia is a type of specific phobia, which is an abnormal and irrational fear of birds. The origin of the word ornitho is Greek (meaning bird) and phobia is Greek (meaning fear). The fear of birds is not uncommon, and it stems from the menacing, darker image of some birds of prey. Sufferers of this phobia might fear that they will be attacked by a bird or may simply be uncomfortable around them.
Some people may only fear predatory birds, such as vultures, while others will even be afraid of household pets in the likes of budgies. The phobia itself causes heart palpitations, sweating, nervousness, and avoidance behavior in those who suffer from Ornithophobia. Without treatment the phobia can become life-limiting.
