Classic agricultural methods boosting biodiversity!

Soils of surface-drained grasslands retained more moisture than soils of deeply drained grasslands. Moisture caused earthworms to contribute to soil processes and being available as food for meadow birds.

Just noticed these upside down spikes in the corners of my hotel room in Spain. What a shitty way to keep the swallows and martins from nesting here. ๐Ÿ˜ช

YOUNG GODWITS, GRAND FLIGHTS - Last autumn two young godwits that we feared to have died suddenly sent amazing data from Senegal. They had flown to West Africa in a non-stop flight. Among them W1WCCG, who achieved an AVERAGE speed >90km/h. ๐Ÿ˜ณ๐Ÿคฏ

A blue and red feathered parakeet? with a simple bar magnet illustration overlayed on it, and yellow lines of force radiating out from the head.  It also has the word "yes*" underneath it.

I stole this from a cover photo for a video on the topic from YouTuber "Learn with Kay" with title "Birds navigte with Magnets in their heads ??" [sic]

We know that birds can sense magnetic fields for navigation. But how does that work?

Do they have little magnets wired up to their brains?

The most likely answer is 1000X times weirder than that, and involves quantum spin.

Let's talk about 'cryptochromes' & magnetic sensing.๐Ÿงช

On the train back home, still buzzing from some great days at @vogelwarte.bsky.social where Hans Schmid wrote "Getrennte Wege" - a classic synthesis of Honey Buzzard migration. A quarter century later the species has revealed a few more, but still not all of its migratory "Geheimnisse". #ornithology

Great day exploring the hills around Sempach ahead of a work visit to @vogelwarte.bsky.social. Good practice wt woodland birds of which I've seen very little since moving to Fryslan few yrs ago. Lovely soundscape wt whistling Red Kite, croaking Ravens, ticking Hawfinch, rattling of Mistle Thrush...

The meadows still have to flood, but the winter bird community at Blaugerzen is starting to form. The first Barnacle and White-fronted Geese are back, and mixed flocks of Lapwing, Starling and Golden Plover are on the fields again. They'll define the birding scene for next five months. #birding

Teenagers SILENE and SPARTINA only reached France and N Morocco on their 1st journey in 2024. Now they caught the wave to W Africa! They flew together for 10h until SILENE split of to land in basins of a phosphate factory. Let's see how far they'll go! 2/2

Over the past 2 weeks, no less than 10 Dutch GPS-#Spoonbills made the crossing from Iberia to Africa. They did so in classic Spoonbill fashion by starting the ocean-crossing near Cadiz, rather than taking the Strait of Gibraltar. 1/2 #ornithology

170.000 RAPTORS IN ONE DAY!

After yesterdayโ€™s heavy rain and a quiet morning, today the sky exploded with Steppe Buzzards and large eagles! Continuing from 10 am until almost the end of the count.

At some point, we counted over 14.000 raptors in less than 20 minutes. THAT'S BATUMI!

After a super intense week with a back-to-back Spoonbill and Wader Study conference, its time to shift to lower gear for a bit. Starting the day with a slow stroll through the fog at Griene Dyk. Hoping for a Yellow-browed Warbler among the plentiful Gold- and Firecrests. #birding

After the thrill of reaching the million, we went straight to the peak of diversity. The challenge of counting high numbers of birds slowly shifted into identifying the (relatively) fewer but more difficult ones: the large eagle species!

But they also brought a special guest along...๐Ÿ‘‡
