Why Evolution is True is a blog written by Jerry Coyne, centered on evolution and biology but also dealing with diverse topics like politics, culture, and cats.
Our reader/photographer in the beautiful wilds of Idaho has been monitoring a nest of bald eagles (two chicks, I believe), and sent these photos of one parent taking wing:
According to EXIF, a Canon 5DIII with a 400 f/5.6. ISO 1000 @ f/1500 @ f/13.
And I know these birds don’t weigh all that much, but it still seems impossible for such a small twig to support that much weight, plus the force of liftoff….

If the initial lifting of the wings were done slowly enough, the bird could lift off with virtually all the force being born by those massive wings alone.
Thanks Ben!
Ben, how do you recommend looking at the EXIF data? I’m not real great on that. Mainly I only see my own, automatically in LR or PS so I never try on others’ pics.
Thanks!
I don’t tend to do that sort of thing very often, so I just fire up Adobe Bridge. Huge overkill and it’s not the best EXIF interpreter, but I don’t remember the last time it didn’t answer whatever question I wanted to answer.
Simply save the file to your pc, JPG format, then if you use Windows, double-click the image and the native Windows Photo viewer will open it. Right-click on the image and select the Properties option. Look under the Details tab to see the EXIF data.
“…such a small twig…”
I think you’re underestimating the scale of the photo. According to Wikipedia, “The Bald Eagle has a body length of 70–102 centimeters (28–40 in).” Picture a meter stick lined up next to the bird from beak to tail. That would make the “twig” it’s perched on around the size of a broom handle or closet rod.
Um.
Okay!
BIIIIIIIIG bird.
(No, not the yellow one….)

These photos are beautiful, and very appropriate after the previous post.
Awe-inspiring. Thanks!
What a pleasure it is to have this crisp and up close view. The simple blue background really makes the bird stand out beautifully. The intense gaze of that bird is truly amazing.
Fantastic!
Wow! Gorgeous photos.
Wow, gorgeous! Thanks for sharing these!
What lens and camera body were used? Thanks!

If I needed more, I’d probably turn to ExifTool.

Thanks again Ben!

And the great news is, now you don’t need any skills or training should you ever decide to go for a Second Amendment “remedy”.
Now, where’d I put that barf bag…?
