New paper with @beatezein.bsky.social & @jedalong.bsky.social:

⭐A new data-driven paradigm for the study of avian migratory navigation⭐

We propose how the multi-modal multi-scale nature of navigation could be studied w/ data mining, machine learning & AI.

A new data-driven paradigm for the study of avian migratory navigation - Movement Ecology
Avian navigation has fascinated researchers for many years. Yet, despite a vast amount of literature on the topic it remains a mystery how birds are able to find their way across long distances while ...

This is WILD.

Power goes out in San Francisco and the robot cars, needing the lights to "self" drive, all stop at once, blocking streets and emergency vehicles - which are needed more than ever in a black out!

We knew AI causes power outages. Turns out it also makes them worse by being stupid.

Waymo has halted service in San Francisco after numerous videos & images showed its autonomous cars snarling traffic during the blackout.

With traffic lights down, Waymos across the city stopped dead in their tracks at intersections.

A bit of solstice cheer from Arran. The "Christmas roses" in my garden are blooming, as is the gorse and more importantly the ivy. The sun didn't show it's face today but a faint glow appeared on the horizon at midday. It may be dark but there are points of light to hold on to.
A greenish white hellebore in flower. A view out to see down my local burn at high tide, a boathouse on the spit and Holy Isle in the distance. It is cloudy but there's a faint glow on the horizon. Vibrant yellow gorse flowers Crowns of ivy flowers and berries.

this field biologist does a great job highlighting the insidiousness of AI editing

these one-click AI edit buttons are incredibly appealing to many photographers, amateurs and professionals alike, and are framed as innocuous

this is worth sharing and educating people about
screenshot of a post on facebook from Alex Lamoreaux, depicting two versions of the "same" photograph of a bobcat in front of a pine plantation, one labeled original game cam photo, one labeling AI processed the markings have been altered on the AI photo, and the head changed and resized text says: Oh! A neat goose hybrid posted to ‘What’s this Bird?’ but when you zoom in on the photos the bill details have been too manipulated by AI photo editing to be accurately assessed for which species may be involved. Scroll on… A cool-looking Red-tailed Hawk that someone is wondering which subspecies it might be - right up my alley! But when you zoom in on the photos literally every feather group has been so heavily manipulated and altered by AI editing that it’s impossible to determine subspecies because the photo is essentially fake now; just a mashup of whatever AI thinks parts of a Red-tail should look like. Scroll on… WOW! That’s a remarkable trail cam photo of a Bobcat! It almost looks like a painting!… but the head looks oddly small…. hmmmm. After some prodding the original photo is produced and sure enough it had been so heavily altered by AI ‘post processing’ that the photo posted was essentially a digital mock-up with totally different proportions and fur markings. No longer the photo off the trail cam; it may as well have just been ‘created’ by AI from scratch. This stuff is killing me. My days on social media are becoming very limited. We can’t even trust simple, everyday photos of animals to be real. The wildlife community needs to quit editing with AI, and we need to start calling out photographers that are using it. Our reality is being destroyed all around us.

64% of vessels operating within Scotland’s Marine Protected Areas (MPAs) are not broadcasting AIS, meaning the majority of vessel activity within MPAs is invisible to the most frequently used monitoring and management systems.

This would allow posting pre-prints of papers that are submitted to journals with a double-blind review, which currently do not allow pre-prints.

A question for science bluesky, is there a pre-print service that would allow anonymous pre-prints? E.g. you could submit a pre-print at the same time as you submitted it as a manuscript to a journal, but the pre-print wouldn't have any names on it until later, when the paper was published. 1/2

A male rock ptarmigan (Lagopus muta) in winter plumage.

Ptarmigan is from Gaelic 'tarmachan' meaning "croaker". The p- was added when people mistakenly assumed it was a Greek word.

A bird forever warning people: "A werewolf!" (just in case of werewolves).

The sunspot number for November is in, and it was a steep drop close to late 2022-levels. We are on the declining phase of the solar cycle.

A "double-hump" solar cycle does NOT seem likely to me, but the declining phase is a very exciting time for aurora chasers, here's why 🧵
