There’s a certain poetic neatness to the Pacific Swifts nesting on the State Ballet & Opera Theatre in the centre of Ulaanbaatar, Mongolia. I bloody love swifts, whether seen high on a mountain top or in the heart of a capital city. Don’t their screams in Summer bring everyone a bit of joy?

There are more than 11,000 kinds of birds. I evaluated them all and made a definitive list of the 100 greatest names. I consider myself a bird name connoisseur but these blew me away. Over the next 10 days I'll add them to this thread. This is the hardest thing I’ve ever done.

Gold is great for forcing rich institutions/funders to pay tho, which doesn’t happen under hybrid models. I imagine this has led to a smidgen more equality North-South 😎. But the biggest winners in all of this are the mega publishers. Gold OA does nothing to reduce their stranglehold on science.

Gold OA has allowed those in the Global South & in conservation NGOs w/out journal subscriptions to jump the paywall, finally. Whilst also, partially (could do a lot better) protecting the ability for those same people to publish through waivers. So there’s also that. #conservationscience 🧪🌍

They might work OK in the Global North, but beyond that, no chance. The training data are just not there yet, and for the long-tail of rare species in the tropics, it’ll take a long time to remedy this. Human experts can often provide likely IDs, by combining data with priors & info on habitat etc.

And as an extension of this: BirdNet and other global AI classifiers are not useful, generally, for biodiversity research. Despite the #AIhype 😏 For example, I saw a recent paper in PNAS using BirdNet concluding that bird diversity was higher in pasture and agriculture than in old-growth forest 🙃

Surprising piece of information: on average, European eel reach sexual maturity at large age than any whale species. And certainly much older than any other exploited fish species. That's why short-term measures are not useful. Eels need a moratorium mimicking the whaling ban (see below)

Celebrated #WorldRewildingDay looking for brown bear signs in a wild corner of northern Spain. Success! Evidence of a bear enjoying last autumn’s beech mast. We also found clues of other interactions with the beech tree: some glistening inkcaps, and a dormice’s cache of hazelnuts inside a treehole

At the sharp edge of defending nature across the planet, rangers suffer. That’s for sure. They are also largely overlooked and undervalued. Hence, the importance of this call for urgent mental health support for rangers👇 Now that we can’t claim we didn’t know, what are we all going to do about it?

Incredibly shortsighted decision by our govt to cut development funding, including taking an axe to nature recovery projects. It diminishes us a country, both at home & abroad. And so we slip inexorably ever closer to the little Britain dream of Farage and his billionaire mates.

Broadly agree, Zack, & really important to hold Starmer to account for his own words! But not sure I agree with the last sentence, at least on current evidence. It doesn’t seem to be the case that Starmer’s doing anything T wants, more that he’s playing the long game.

Although we have known this for many years—e.g. @neobirdconserve financed early work by Vitek Jirinek—this should have been the top news headline last week. These declines in 'pristine' tropical forests are well-documented, poorly understood and continue apace. www.science.org/content/arti...

Yep I agree, SCR certainly not easy, but the statistical foundations are solid, and it’s easier than the ‘unmarked’ route (REM/REST etc.)! There’s no reason why it shouldn’t be being applied across lynx populations in Europe in a standardised way. Interesting study, too, thanks for sharing!

Lynx (including Eurasian) are actually one of the “easier” ones, since you can identify individuals (unlike for, say, deer). Done with good survey design (and that doesn’t mean throwing a few cameras up and hoping for the best 🤓) and analysis, you can get an accurate & precise population estimate.
