Can anybody help me?

You can get some bird sounds from a modulated chorus pedal.

I still say make them yourself. Get yerself a guitar or just the pickup and some strings. Face it towards the amp or whatever is your sound producer.

Just sample a clip from a live album from like My Bloody Valentine or God Speed You! Black Emperor or better yet since you are in Japan go see some guitar monsters like Merzbow or Acid Mother Temple and bring a mini disk. There are tons of people doing noise and guitar art in Japan.
