At what height does a pigeon sky out in clear conditions? Turned my tipplers out today and as I was picking tomatos and peppers in the garden, I looked up and they were just gone... After a few minutes, I finally saw tiny dots, so small I couldn't even see wings flapping. Later they disappeared from view again and they're still up. Usually they only go up about 100ft. But at what height does a bird "sky out" or become less than visible to the naked eye? I was told by one guy that it was about 1500ft but I was curious what other people thought?
