Would have been really interesting if that was the real result of the SDM.. Luckily, it was just a small mistake in my R code.

In Defence of Bird Conservation in a Broken World
In a world torn by wars and crises, bird conservation can seem irrelevant. Yet to protect life itself is not indulgence – it’s resistance.

Just started reviewing a paper that's supposed to be double-blind. There are indeed no names in the document, but the file names are the name of the first author...
Which made me think - how often do you really not know who's paper you are reviewing?

A second paper from the story of the discovery of the Egyptian #Nightjar in the Dead Sea area was published recently.

A new study led by @moveandconserve.bsky.social used GPS tracking to test the monitoring potential of Eilat and Batumi.
An invaluable step toward linking counted birds to their origins, but we found it needed some elaboration from a migration count perspective!

Yes! I like the idea!
But why stop there? What about removing human settlements from remote areas so that Putin can't attack them (and to reduce human effects)? Reducing the number of flights to avoid being targeted (and reducing CO2 emissions)?
Any other ideas?

If you don't know it, it really is an amazing tool (with some problems, obviously). The most important thing is that it allows me to read (well, hear) a few more papers, missing a little less of what's new in science.
