introduced to a brand-new GoComics! See more information here. Subscribers, check your

Mrs. Olsen: The Condor is very special bird. It can fly as high as 15,000 feet. Caulfield: Ooh! Ooh! How does it do that without supplemental oxygen? Mrs. Olsen: By being very special. Caulfield: If that's an approved answer on tests, you just changed my life.
You can see California Condors perching and flying at Pinnacles National Park (the “newest” national park, previously a national monument since 1908). I’ve seen them flying at Pinnacles and at the Grand Canyon. They seldom flap their wings once they’ve taken off. Maybe they’ll multiply (slowly) in the wild if California successfully bans lead bullets and lead shot.
Ted Wade: One early wind farm at one site, and petro-addicts think it is standard. It isn’t. Danish studies show birds avoid the whole array as a single object – except for cormorants and gulls which find the service platforms ideal nesting sites. Skyscrapers kill hundreds of times more birds than windmills – try outlawing them!
@hippogriff: I know in San Francisco any new buildings (yeah, it’s a little late, but) have to have windows that are more bird-friendly, less reflective if I remember right.
Interesting to realize that in WWI planes few as high as 25,000 feet – without oxygen. Some pilots may have passed out, we will likely never know. Since many people have summited Everest without ancillary oxygen it is clearly physically possible.

A friend of mine was a radio operator on a B-36 years ago. He told me they once observed a vulture at 29,000 feet.

Your all missing the point she should have said “Excellent question Caufield – that is your homework for tonight”

amaryllis2: Thanks for the information. It is not only too late, but too local. Let’s hope it spreads. I will do my part, such as it is.
