Today at the Chimney Swift roost... #birds
Fun fact - the tree they are roosting in is well over 300 years old and has its own Wikipedia page:

Chimney Swifts filtering into a tree cavity shortly after sunset. Right in the middle of UNC’s campus! Draws a crowd every evening while it lasts. They’ll soon migrate south for the winter. Very fortunate to witness them using a natural roost. Shown in thermal infrared. #birds
Do you like birds? Do you like maps? Do you like birds AND maps??
I made maps for every species in the US, showing where they've been recorded, and how recently, at the county level. Check it out! #birds

This is how Reddish Egrets hunt for fish. By prancing through the water. #birds
I took some comet pictures and I stumbled on two cool things about it.
1) The comet is casting a shadow on its own tail - you can see a faint dark line down the center of the tail.
2) There's like a second faint line pointing in the opposite direction of the main tail
Perhaps the other line is the “anti tail”? en.m.wikipedia.org/wiki/Anti…
here's the comet at 85mm
also I think there are like 10 starlinks in this one picture, that's a new one for me, having not done much astrophotography in a while
