Midway Atoll has a new cam that allows you to see intimate moments in the lives of Laysan albatrosses. I wrote an article for @smithsonianmag.bsky.social about what to watch for... @friendsofmidway.bsky.social, @explorerwieteke.bsky.social www.smithsonianmag.com/science-natu...

You can see the large white seabirds dancing, preening, feeding and raising young—though the live feed might show a dark side of island living, too, with potential predation from invasive mice

Just reposting this which I think is the most gorgeous thing I have seen in my career - a critically endangered orange-bellied parrot feeding on a carpet of daisies after an ecological burn. This was the first time they’d had the chance to feed naturally in 15y and was wonderful to witness 😭😭😭🧡🧡🧡🧡
