todaysbird:

a rare closeup of a black swift, found throughout north america and small parts of south america. swifts are rarely seen up close; they spend more of their life in air than any other species of bird – they eat, drink, mate and sleep while in flight. they are incapable of perching like other birds; they must cling to vertical surfaces.

I had to look this up because “sleep while in flight” ????

but yeah, apparently completely true.  these birds stay aloft for as much as 10 months nonstop, feed on insects, spend more energy at night (when there aren’t warm thermals to ride) and at dawn and dusk climb to 10,000 ft altitude where the 30 min slow descent is probably when they catch their sleep.

they’re unusually long-lived for such active critters (20 yrs) and they may be limiting energy expenditure by being extremely aerodynamic and narrow bodied.  Also a single bird travels the distance of about 7 roundtrip journeys to the moon in its lifetime (>3 million miles).

Reminder: this is a dinosaur.

Oh wow guys I need to tell you something amazing! So one of my collegues at my old university just reported that they found 300 frozen roundworms in the permafrost in the Kolima region of Russia, they unfroze them and… 2 of them were alive and started feeding!!! One of them is 41700 years old, the other is 32000 years old.
