"Ze gaan hout hakken"

The local fens now have a shockingly low water level due to the drought. One small positive side effect: the migrating common snipe who love to forage along the water's edge, preferably from the cover of the reeds, have to come out. Absolutely stunning birds, and very alert. #birds
A common snipe walking along the water's edge, but looking up as it is very wary. The common snipe has reasonably long yellow legs and a very long bill, with which it usually pokes in the mud for food. Its plumage is spectacular: various hues of brown, white and some black, mostly in a stripey pattern to provide better camouflage. The bird is mirrored perfectly in a reflection in the water below it.

Thank you AB! Shooting in the rain is a challenge but (with weathersealed gear, a crucial condition 😅) it can lead to some very cool results! A nice theme for today. :)

The first time I saw an overwintering red-breasted goose (roodhalsgans), the skies suddenly opened and covered all of us, man and bird alike, in something in between hail and rain. Luckily it lasted only a moment! #BirdOfTheDay #BadWeather #Birds
A group of geese in a field with small drops raining down on them. Most of the birds are greater white-fronted geese, but in the centre stands a red-breasted goose, standing upright and flapping its wings - black with white stripes. Because the light has mostly gone the bird's dark red breast and throat no longer stand out as much, but with some effort they can be made out, as can the white lines separating the black and red parts of his neck and face.

Nee precies. Ik ben benieuwd wat er op de kaart overblijft als je de gevallen wegfiltert met maar één melder en zonder bewijs. Maar duidelijk is in ieder geval dat er echt een klein golfje begonnen is, dus dat biedt hoop!

Maarja, zuidoost is ook wel de laatste plaats waar ze logischerwijs doortrekken.

Die bij ons was ook twijfelachtig en niet door meer mensen dan de melder gezien, helaas

Er kan natuurlijk ook een soort van massapsychose ontstaan onder vogelaars waarin iedereen denkt notenkrakers te zien... gelukkig is er bij veel gevallen bewijsmateriaal

Today's #BirdOfTheDay theme is #WingsOpenNotFlying and this guillemot (zeekoet) coming ashore is a nice example of that. With the proportion of body size to wing surface it's a bit of a miracle these birds can still fly! #birds
A guillemot coming ashore, standing upright on some rocks as it flaps its wings to dry off. The bird is black and white, and facing us its bulky white torso stands out. Half of the birds head, including the chin and the side of the head, as well as most of the downy looking under wing are also white - in other words, all the parts of the bird that would be facing the water when swimming. The back and upper parts of the bird, as well as the legs and bill, are black.

There's a modest population of red crossbills (kruisbek) in the woods near Nijmegen, supplemented with more birds from the north during winter. It had been a while since I saw one, so on friday I set out to find one, and after some pretty intense searching I was happy to succeed! #birds
A red crossbill in the top of a pine tree. It is sitting very upright and has a rounded head. Its bill is curved upward and downward, although the curve upwards is obscured here.

De toename van de oehoe in Nederland gaat echt bizar hard, we zitten ondertussen op 120+ paartjes (gegevens van vorig jaar), dus de kans om ze tegen te komen wordt ook steeds groter.

Kor Bosch @korbosch.bsky.social · 03/10/2026
Deze tijd van het jaar gaan uilen op zoek naar territoria, dus dan kunnen ze ook opduiken op onverwachte plekken zoals woonwijken, en soms blijven ze een paar dagen hangen als er veel eten te vinden is (zoals duiven). Met wat geluk overdag dan in een boom of op een dak te zien!

I had forgotten to post this image from last month - an upside down Queen of Spain fritillary (kleine parelmoervlinder) on the heather, a stunning butterfly. It had been a few years since I last saw one so I was very happy to see it!
Purple flowering heather with a Queen of Spain fritillary butterfly on it, seen from below and upside down, with the light against it. This is a mostly orange butterfly with black and white spots, with the white spots looking like pearls, after which the butterfly is named in Dutch.

The #BirdOfTheDay theme is #BokehBirds, and this spotted flycatcher (grauwe vliegenvanger) on a branch qualifies quite well. This was a parent from a nest I discovered back in 2024, right next to a foot path, and they could usually be seen foraging right next to the path.

Oh wat stom, Geert. Is dat alleen voor het vignet of ook voor de boot? Als je het relaas aan me doormailt gooi ik het in het VWG-bestuur, want het lijkt me niet dat jij hier voor dubbele kosten moet opdraaien.

Maar zilvermeeuw/Pontische meeuw/geelpootmeeuw is ook wel de grootste uitdaging van allemaal, haha 😅

Klopt niet helemaal denk ik - Pontische en geelpootmeeuw staan hier niet op en zijn allebei algemener dan dwergmeeuw (en broeden hier ook, itt die soort). Bij ons zijn ze ook een stuk algemener dan zwartkopmeeuw, maar dat zal bij jullie langs de kust wel anders zijn.

These kestrels (torenvalk) I saw today weren't really hidden, but the patterns on their plumage made them blend in surprisingly well. I don't often see a pair together like this, resting in a tree, as they're often out hunting individually. #BirdOfTheDay #Pairs #birds
A male (left) and female kestrel in a tree. The tree still has plenty of leaves, and although only a few are in front of the birds, their spotted plumage and brown colours make them blend in surprisingly well.

One of the local beaver lodges had a visitor - a common kingfisher (ijsvogel), resting on a branch sticking out (on the left). Kingfishers can benefit from beavers, too, and I've often seen them near their lodges, dams and pathways. #birds
A huge beaver lodge on the water's edge, with foliage behind it on the landward side. A branch sticks out to the left, and a kingfisher is sitting there with they bright blue back turned towards us, looking up towards the right with its head visible in semi-profile. The bird's bill catches the light.

Sometimes when you see an image you have an irrepressible immediate association.
Het spel "Wie is het" met alleen vrijwel identieke portretten van clerici, in dit geval de martelaren van Gorcum.
The game "guess who" but with only near-identical portraits of clergymen, in this case the "Gorcum martyrs".

Treurig, het ontbrak bij het volledig op machtspolitiek gestoelde stemadvies van de partijtop zowel aan idealisme als aan inzicht of zelfs maar interesse in de vraag waar de beide blokken eigenlijk voor staan. Echte discussie ontbrak. PES is niet mijn partij in de EU.

A carrion crow (zwarte kraai) parent was trying to feed the kids, but they were at serious risk of poking the parental eyes out in their enthusiasm, so they had to be kept at bay at the same time. It isn't easy being a crow parent! #BirdOfTheDay #Corvids #birds
A crow parent, on the right, holds a piece of wet bread (it had been dipping it in the lake) and is being swarmed by two juvenile crows who are snapping at the food. The parent turns their head away so as not to get their eye hurt more (both eyes were already showing damage likely caused by the kids!), and sand is kicked up by all the crows in their enthusiasm.

Maar hij wordt toch echt genoemd in een contemporaine beschrijving van de viering, in 1741, van het 150-jarig bestaan van het Arnhems muziekgezelschap St Caecilia (waar de vernoeming op gebaseerd is), zij het met umlaut. Het Fuckspad mag dus wat langer blijven bestaan.

Bij de Arnhemse straatnamencommissie kregen we de vraag of de naam van het Fuckspad, volgens de administratie vernoemd naar de 18e eeuwse componist Valentini Fucks, wel klopte. Over de componist kon ik niks achterhalen en ik betwijfelde daarom of hij had bestaan, zodat ik op onderzoek uitging.

Caspian gull (Pontische meeuw) is now so common in the Nijmegen region that I come across them as often as I do herring gulls (zilvermeeuw). Two hours after passing by this juvenile, an adult Caspian gull was in the same spot, so it either aged two years in two hours or another bird arrived. #birds
A second calendar year Caspian gull in flight, with the light behind it shining through its wings, giving it a nice outline effect. Only in its fourth year will this gull have fully adult plumage, when it will be harder to identify from herring gulls. With more juvenile birds the main standout is often that its head is much paler than that of herring gulls of the same age, but it remains tricky. I always try to ID all similar large gulls (herring gull, Caspian gull, yellow-legged gull) I see, just to get more of a feel for it.

A hobby falcon (boomvalk) just casually snacking on a crane fly (I presume - a very long-legged insect at least) in mid-air, in the Millingerwaard today. #birds
A very stripey falcon has just caught an insect with very long legs with its claws in mid-air.As it flies, the hobby leans forward a little to inspect its catch - its long legs are bent forward so it claws level with its beak. Its upper legs are covered in feathers, as stripey as its chest.While still in flight, the bird is leaning down and eating straight from its claws.The hobby is still soaring and munching, with long crane fly legs seen extending from its beak.

This is one of my favourite #silhouette photographs, today's #BirdOfTheDay theme. A song thrush (zanglijster) caught mid-song hidden in the foliage. #birds
A song thrush is singing on a branch. It is visible only in silhouette, in a singing pose, with its lower bill reverberating in song. Behind it verdant green can be seen from the leaves.

(Yes, to my surprise the swallowing attempt was somehow successful.)
The herring gull makes an enormous swallow to consume the crab. Its tongue protrudes and its throat is clearly full up.

A herring gull (zilvermeeuw) attempting to swallow a crab, who objects. Seemed like an appropriate image for today's #BirdOfTheDay theme #mouthful! #birds
A herring gull is swallowing a living crab. Obviously crabs have lots of pointy parts so, before attempting to swallow, the herring gull spent a fair amount of time positioning the crab just right, so that its legs and claws would go down with the smallest risk of wounding the bird. The claws, and some legs, protrude from either side of the gull's mouth.
