I also love they've now got the second language abstracts option! Meanwhile, some other unspecified publishers using a combination of multiple fonts to spell my surname (Minařík) correctly throughout our paper 😂

Hi, thanks! I'd love to join if you can add me 😊 If you take hobbyist nocmiggers, that is. I'm more into fish electroreception during the day 🙂

The call example also (in fact, mainly) including Chiffchaff also doesn't help 😅

The sound example they provide here is a bit confusing. There's a Chiffchaff calling in it, too - in fact, the first two sharp calls are Chiffchaff, only the third is the Yellow-browed Warbler.

Interestingly, while Sturgeons cannot swim backwards, they seem to be able to speak Spanish backwards 😅

That sounds great, thanks! Will have a look!

Bike twitching should be the only acceptable form of twitching! 😂 Lovely bird!

Thanks! Might give it a go then, but at this stage I still prefer improving my ID skills by manually raking through all the recordings 😃 Will need those later to be able to assess which classifier works best for me anyway, and how reliable they are 🤷🏻‍♂️

Thanks! No, slowly working through it, the old-fashioned way. Tried BTO Acoustic Pipeline, but seemed to be missing quite a lot of the faint calls, and misidentifying some loud ones (Wigeon/Oystercatcher being repeatedly suggested for what was a resident Little Owl). May give it another go, though.

Don't get too excited about the landfowl NFCs. The first one is a Quail, yay! But the other two are just Pheasants. Nocturnal migration? No. Nocturnal flight call? Yes, if a few meters worth of escape flight after being flushed by a fox, or something, counts :)

Maybe just for better readability, here's the same data split by major bird taxa.

Waders are more evenly distributed throughout the year. This will a nice one to plot by species at some later point. Same with rallids, in fact. Anyway, back to IDing now, I guess 😂

Overwhelming majority of the autumnal songbird flight calls are Redwing. They clearly cluster into nights with lots of movement. The concentration of rallid calls (Moorhen, Coot, Water Rail) into spring months is also nice 😊

Interesting! I would have thought they'd rely on electroreception from early on, considering their head is already practically covered with ampullae of Lorenzini at the onset of feeding (doi.org/10.7554/eLif...).

Meanwhile, Redwing counts indicate these winter thrushes are already leaving East Anglia for Scandinavia, while Moorhens and Coots will be ramping up their territorial flights with the coming spring. Good to hear a Barn Owl above our village too, along with the usual Tawny.

Here's a screenshot of a spectrogram of the Stone-curlew as shown in Audacity.

After you posted this, a Stone-curlew flew over our Cambridge garden the following night 😊
