Lost grey parrot in Prawet, please help

My African grey parrot flew out of the window on Sunday afternoon and we have not found him since. He is about 4 years old, grey with a red tail, and he answers to his name when called. He is fairly tame, but he will be scared outside and may not come back when called. He was last seen near the canal behind the Prawet market area. If you see him, please do not chase him, just message me in the app and I will come right away. I check the app all day.
