hoothoot doesn't learn fly by itself, in fact NO Pokemon does. You have to teach fly to it with a HM. In diamond/pearl/platinum, you get it in team Galatics wherehouse in Veilston city. In soulsilver/heartgold, after you defeat Cianwood gym leader Chuck there's a lady outside of the gym that gives it to you when you talk to her. In Black/White, after you defeat the Driftveil gym leader, you fight Bianca and she gives it to you. I hope this was of some help, if not, I got all this off Google...
