TIL that the ruby-throated hummingbird flies non-stop across the Gulf of Mexico as part of its spring migration and has a VO2 max that is about 10 times higher than elite human athletes. (en.wikipedia.org)

From the article:

This feat is impressive, as an 800 km (500 mi), non-stop flight over water would seemingly require a caloric energy that far exceeds an adult hummingbird's body weight of 3 g (0.11 oz). However, researchers discovered the tiny birds can double their fat mass in preparation for their Gulf crossing, then expend the entire calorie reserve from fat during the 20-hour non-stop crossing when food and water are unavailable.

This is nuts!

Birds are fucking crazy.

IIRC, they come back to the same exact location as the year before. Can't tell if I'm seeing the same ones.

I've heard similarly. I guess you're just going to have to introduce yourself and get all their names. But don't tell them they all look the same. Birds find that offensive. 🙃

Additionally, it would be appreciated if the location of the sighting and a date were given when a photo or question is posted. You do not have to give the precise location, something like "Northern Idaho, June 2023" or even "North-Western US, June 2023" suffices.
