The front half of the image is made up of vegetation in various hues of red and orange: this is glasswort or marsh samphire. The back half of the image is overexposed: these are mud flats carrying the reflection of bright sunlight. At the front of the mud flats, close to the red vegetation, a single oystercatcher stands at rest on one leg, its long bill tucked under its wing. Behind it, various groups of birds, mostly oystercatchers, can be seen resting. Some bright green lines cross through the mud flats, probably algae or other sea plants that have washed up on the flats.

More housebound than I'd like at present so here's a coastal image from October: glasswort (zeekraal) turned red on the Schiermonnikoog coast, with wading birds like oystercatchers resting on the mud flats, turned a bright white by the reflection of the sun. #birds

Echt benieuwd of ze dit laten staan! Het is ongetwijfeld behandeld hout en nu is de vraag dus of dat het meer of minder lekker maakt...

Haha, ja ze zijn uiteindelijk niet heel kritisch. Bij mij zitten ze ook gewoon in de woonwijk! Er is een plek waar ze steeds jonge boompjes langs het fietspad omknagen, en dan plant de gemeente steeds nieuwe boompjes bij, echt heel handig voor ze.

The number of species that visited during garden birdwatch was actually fairly limited this year - the great tits and blue tits, which are normally very present, remained absent. But the wren and robin did show and they're rarer visitors, so I was fairly satisfied. #birds #tuinvogeltelling

Four long-tailed tits eat from a bird feeder stocked with fat balls

It was nice to see a group of five long-tailed tits (staartmees) arrive in my garden this afternoon - they've only started visiting recently! Four swarmed the feeder while a fifth kept watch from a distance. #tuinvogeltelling #birds

De economische keuzes van het nieuwe kabinet zijn vooral goed voor het bedrijfsleven Het regeerakkoord is een integrale vertaling van het rapport Wennink: zoveel mogelijk publiek geld richting bedrijven, en zoveel mogelijk regels voor bedrijven afschaffen.

In de week dat ASML een winst van 10 miljard bekendmaakt en ING een winst van 6 miljard haalt het nieuwe kabinet de miljarden bij… de mensen.

Hoe werkt de Tuinvogeltelling? Doe mee met de Nationale Tuinvogeltelling? Vogels tellen in 3 stappen.

Maar bij ons mag het helaas niet, wij zijn veel strenger dan de Britten: www.vogelbescherming.nl/tuinvogeltel...

A long-legged bird with brown back, white belly and fairly long bill walks along a line of sand surrounded by water. It is walking away from me, but looks over its shoulder in my direction.

A common sandpiper (oeverloper) about a week ago. A small, easy to miss wading bird that allowed me to come pretty close as it was foraging along the shoreline of a local lake. #birds

I did just see they have a tiktok video out also debunking fried rice syndrome by name, emphasising that it's okay as long as you store it well, so I guess they're doing their best now to combat the myth!

Bacillus cereus Bacillus cereus is een bacterie die voedselvergiftiging kan veroorzaken. Het kan voorkomen in voedsel dat te lang en niet koud genoeg bewaard is. Meer weten?

The Dutch official voedingscentrum used to warn against reheating takeaway rice in the past. Their take is more nuanced now but the same idea is still there, although the problem according to them is not with reheating itself but with improper storage: mobiel.voedingscentrum.nl/encyclopedie...

Nee, ze eten de stenen niet op Maar we zien ze wel stenen slikken soms. Het doorslikken van de stenen heeft een andere functie.

Slechtvalken gebruiken ze in ieder geval wel: www.vogelbescherming.nl/beleefdelent...

Dank je! Daar lijkt het inderdaad op, maar de lichte stip is niet de iris maar de reflectie van de zon op het oog. πŸ˜… Het oog van de ijsvogel zelf is helemaal donker (hier met semi-transparant knipvlies eroverheen) en daardoor is het moeilijk te zien waar hij (in dit geval) naar kijkt.

A kingfisher flying past me at fairly close range. Its nictitating membrane is closed - this is its "third eyelid", a very thin, translucent eyelid that can close without fully impairing the bird's vision. The colourful bird has an orange belly and its wings, back, cap and moustache are all greenish blue. The bird, with a fully black lower mandible, is a male.

On my walk yesterday a kingfisher (ijsvogel) suddenly flew past at quite close range. I was lucky to respond fast enough and got a sharp photograph when he was about to pass me, just as he blinked with his nictitating membrane (knipvlies). #birds

The bird flies off into the distance above the smooth water surface, which perfectly reflects the bright orange underside of the bird. The reflection is mostly black from the shadowy water side, but on the lower half of the image vertical lines in the water show the reflections of individual trees.

After discarding his catch, which appeared to be a bit of vegetation, he flew off again. #birds

The kingfisher emerging from the water, his beak (holding its faulty catch) pointing downwards and water drops flying above and around it, with everything perfectly reflected on the smooth water surface.

The kingfisher emerges further, its entire head and beak becoming fully visible now. You can see the bird is making tiny flaps with his wings to propel himself out of the water.

I know this kingfisher's favourite fishing spots, which are hard to see as they have a lot of cover, but he surprised me by fishing from a nearby fencepole stuck in the water. And I surprised myself by getting sharp shots of the small bird emerging from the water after his dive! #birds

A sandy hill with a shrub on it and covered in a light sprinkling of snow. Four small birds sit in the shrub, three of them prominently at the top and one towards the bottom.

A group of four twite (frater) has ventured further south than they normally would. These birds only visit the Netherlands in winter, when they tend to stay along the northern coast, so where I live these are considered a rarity. They've now made their home on an unappealing island. #birds

A kestrel sits on top of what appears to be a large plank pointing up. In one claw it holds an already dead meadow pipit, one of its legs pointing upwards, lumps of ice sticking to its long nails.

Meadow pipits (graspieper) were foraging in a group along the snowy Beuningse plas on this very cold day, when a common kestrel (torenvalk) saw an opportunity and snatched one. Small lumps of ice were still stuck to the pipit's long claws. #birds

A brownish bird on a snowy, stubble-covered field. The woodlark has a very distinctive whitish eyebrow. It has raised its crest and looks altogether more orb-like than it would in spring or summer. Its plumage consists of lighter and darker shades of brown with a lighter belly and striped chest. There are dark brown triangles on its wings.

An image from an earlier winter, but appropriate considering the current weather conditions here. A woodlark I discovered not far from my then-house, foraging for food on a snowy field back in february 2021. It had puffed itself up a bit against the cold. #birds
