So, I went for a run earlier today, and stopped to look for a new song on my iphone. I looked up at the beautiful blue sky, as the weather is quite lovely these days. I noticed what seemed to be moving black dots, scattered about the billowy clouds. I kept staring, mesmerized, realizing they were birds, as they swooped down, then shot up to ''touch the clouds,'' once more. Perhaps, it was merely an optical illusion, but I didn't realize that birds flew so high. And then...I discovered this: https://www.birdnote.org/show/how-high-birds-fly-i
An alternative question would be "How low, birds go"? While (scuba) diving in the PNW I've occasionally seen birds under water (Cormorants). I knew that some birds dived out of the sky to grab a fish (like Bald Eagles) but I didn't really picture them being able to stay underwater. If figured their air cavities would cause them to bounce back up immediately. They are quick so most of the time by the time I noticed one was underwater they would be zooming back up toward the surface. I was on a dive once though where one came down and stayed down for a short period of time and chased a fish down by swimming in a rapid zig zagging pattern. Bird fly high and dive low.

Wow, that's so amazong! I didn't realize what remarkable creatures they are! How incredible to be able to soar to such great heights, and dive beneath the ocean to extreme lows. I'm a bit jealous, they have the best of both worlds. lol
True, but it seems like a lot of work to be a bird. Please Register or Log in to view the hidden image! How high butterflies fly?
Some eyewitnesses have spotted butterflies soaring as high as the top floor of the empire state building. Please Register or Log in to view the hidden image!
We you must admit not many fish in the upper atmosphere Perhaps a few after cyclone/tornado Please Register or Log in to view the hidden image! Please Register or Log in to view the hidden image!
occasionally high flying air craft strike birds https://www.flightglobal.com/news/a...tigate-high-altitude-bird-strikes-nea-334523/ 06 November, 2009 SOURCE: Air Transport Intelligence news BY: John Croft Washington DC
some migrating birds wait till the right weather conditions then use thermals to ascend so they can fly to other countrys. eagles & condors & some sea birds can be seen doing this quite commonly. they can only go as high as the thermal will allow generally speaking while some birds get carried off into the wild blue yonder, possibly frozen to death while in the air. i would guess their tiny little frantic hearts would simply give out.
