Cool. Birds do seem to have amazing eyesight.

I have never been able to understand how a hawk can see a squirrel in a tree from 1000 feet up anyway.

Very interesting.

Most birds have incredible eyesight and pigeons also have incredible visual memory.

As a curiosity here are 2 videos regarding bird vision:

I feel like 1000 feet is a low estimate for some birds, from what I've heard.

Birds of prey have moved back into my parents neighborhood, as I think the neighborhood environment has improved enough from the environmental ransacking when the neighborhood was built. My dad entertains himself in retirement by watching Hawks pick off the squirrels in the backyard.

Actually, the "wild" squirrels flee as soon as development begins, and it takes several years before "city" squirrels move back in to take their place.

Interesting and understandable. They also are keeping the stray cats at bay. Even in a limited form, it is great to see more nature return to a developed suburban environment.

Ducks are best. Own the water, the ground and the air. Can identify mechanical keyboards in a pile from an eBay potato picture with 99% accuracy.

Also beautiful and delicious. What more could you want?

Looks like I was drunk typing last night.
