Hey! Total eclipse in the U.S. tomorrow. People are driving to watch from all over the country. The whole continent even. The last one was in 1991. So this one’s a pretty big deal. First time ever that 20 million cell phones witness a total eclipse.
Be careful if you go. Some say they have a profound effect on people. I can see that. This one may cause the biggest traffic jam ever.
And if you are planning to watch be sure to use those special glasses. I’m sure you have a pair and are all ready. But if they were out of them at Walmart don’t worry. They say you can still look at it. But only during the couple odd minutes the moon completely covers the sun. And never, never look at even a sliver of sun. I see a problem with that. How do you know when not to look? Without looking?
Oh, and be careful. I read there are knockoffs out there that are nowhere near dark enough. Your retinas could be toast. If they’re good glasses you shouldn’t be able to see anything besides the sun. (Be careful walking around in them while testing yours.)
So what if they don’t meet the test? NASA says there is still a way.
Wear a welder’s helmet. No kidding. If you have one. But even then it needs a special lens. Extremely dark. Class 12 or something. For special kinds of welding. Very uncommon. So NASA says be sure to check the class. Because you probably don’t have one.
So now. Finally. How will birds act?
Take this tiny Northern Pygmy Owl. Here are a few facts. He is only 6” long, give or take an inch. Spread your forefinger and little finger wide open. Like Texas Longhorn fans. (Texas A & M alumni use your imagination.) The distance from pointer to pinkie is about how big this owl is. Top of head to end of tail. But he’s all heart. He can take prey as big as pigeons. Even chickens.
And he’s diurnal (see Bird-nerd-word.) That’s birder for “flies-around-in-daylight.” So. Will two and a half minutes of darkness during the day make any difference to him?
Who knows? Certainly not me. And I’m not alone. No one Knows.
But scientists are intent on finding out. So they made an app. iNaturalist. They want people to report what birds are doing before, during and after the eclipse. Good idea. I hope you’ll take part.
But there is one thing that’s not clear to me. How are you supposed to watch what birds are doing?
You’ll be in the dark.
Wearing a welder’s helmet.
