Well... I can actually tell you how to get rid of this fear because, I suffer from it, I am terrified of pigeons... and I have no idea from where it started... Im only 17 years old, and I hate to have this problems, because when Im on the street or school I always have to change route or ask a friend to scare them away (and well... you can imagine thats pretty embarassing thing for a teenager...) rigth now, I just what to know the technical name of the fear...
