The #BirdofTheDay theme is #ScreenFiller. This Eurasian Eagle-Owl clearly did not get the memo about personal space. Filled the frame and half my heart rate along with it. Bubo bubo (Oehoe) #birds #birdphotography #vogelfotografie #natuurfotografie #natuur #SonyAlpha #EastCoastKin

Close up portrait of a Eurasian Eagle-Owl (Bubo bubo) perched among green tree foliage, filling most of the frame. The owl has large piercing orange eyes with dark pupils, prominent ear tufts, and finely mottled brown and black plumage with dense vertical streaking on the chest. Its head is turned slightly, gazing directly at the camera, while dappled sunlight filters through the surrounding leaves, creating soft highlights on the feathers and a blurred green background.

Stillness with a blade for a beak. The heron waits, patient as water, eye fixed on something only it can see. #GreyHeron #Heron #birds #birdphotography #SonyAlpha #EastCoastKin #BlauweReiger

Today's alternative #BirdOfTheDay theme is #BlueSky. A master of camouflage caught in the open. This nightjar's mottled brown and buff plumage is built to vanish into bark and shadow, yet the last golden light gave it away on this weathered branch. #birds #birdphotography #SonyAlpha #EastCoastKin

A nightjar with cryptic mottled brown and buff plumage perched sideways on a bare, weathered branch, illuminated by warm golden light against a plain pale blue sky.

Today's #BirdOfTheDay theme is #BathTime. Bath time at the local spa, no reservation needed. This Hawfinch (Appelvonk) brought its own splash package. 😉 #birds #birdphotography #vogelfotografie #natuurfotografie #natuur #wildlife #SonyAlpha #EastCoastKin

A Hawfinch (Coccothraustes coccothraustes) bathing in shallow water. The bird has a massive pale blue grey bill, dark eye, and black bib, with a warm buff head and chestnut wings showing a bold white wingbar. It is captured mid-bath with tail raised and wings slightly lifted, sending up numerous water droplets around it. The background is a soft blurred wash of warm brown and green tones.

Today's #BirdOfTheDay theme is #Orange. All that blue gets the attention, but the real theme colour is quietly sitting underneath. #Kingfisher #IJsvogel #Alcedoatthis #birds #birdphotography #birdwatching #vogelfotografie #natuurfotografie #SonyAlpha #EastCoastKin

A Common Kingfisher (Alcedo atthis) perched sideways on a thick, gnarled branch, facing right. The crown and back show iridescent turquoise-blue plumage with fine dark speckling, while the throat is white and the breast and belly are rich rust-orange. The long, dagger-like bill is dark with an orange base near the lower mandible. The bird sits upright with feathers slightly puffed, tail pointing down toward the branch. Background is a soft, warm, out-of-focus blend of olive-green and brown tones. Natural light highlights the sheen on the wing feathers. Photo by Geert Klein Breteler.

The #BirdOfTheDay theme is #Ebony&Ivory, birds that have Black & White plumage. Mirror check before the start of the day. Pied Avocet (Kluut), always sharply dressed, even in still water. #blackandwhitephotography #wildlifephotography #SonyAlpha #EastCoastKin

Monochrome image of a Pied Avocet (Recurvirostra avosetta) standing in calm, still water. The bird is preening, with its head turned back over its shoulder and its long, thin, upcurved black bill tucked into its back feathers. Plumage shows the species’ characteristic bold black cap and nape contrasting with pure white body feathers, with sharp black markings along the folded wing. It stands on two long, slender legs, partially submerged, casting a soft, blurred reflection on the water’s surface below. The background is rendered in deep, uniform black, isolating the bird against the dark tone and drawing full attention to its shape and plumage pattern. Lighting is high contrast, emphasizing the separation between the ebony and ivory tones of the feathers. The composition places the bird slightly left of center, with negative space and its mirrored reflection balancing the frame. Photo by Geert Klein Breteler.

Today’s #BirdOfTheDay theme is: #WildMotion, Dynamic wildlife behaviour, freezing a second which is full of energy. Shift change at the nest hole. One in, one about to leave. #BlackWoodpecker #ZwarteSpecht #birds #birdphotography #vogelfotografie #natuurfotografie #SonyAlpha #EastCoastKin

A pair of Black Woodpeckers (Dryocopus martius) at a nest hole during a nest relief exchange, on a tree trunk covered in bracket fungus. One bird clings at the entrance with its full red crown visible, about to enter or having just left. The other bird is captured mid departure, wings raised, head turned away from the light. Soft background of budding branches and blue sky. Photo by Geert Klein Breteler

Ik pleit al jaren voor meer vrouwen in de politiek maar als ik gisteren tijdens het #stikstofdebat deze drie zoveel onzin uit hoor kramen vallen de vrouwen me vreselijk tegen. Gelukkig was daar ook @laurabromet.bsky.social om het te compenseren.

Chestnut crown, black mask, mind elsewhere. A shrike lost in thought against an empty sky. Perfectly matching today’s #BirdOfTheDay theme #QuietReflection. #WoodchatShrike #Roodkopklauwier #birds #birdphotography #vogelfotografie #natuurfotografie #SonyAlpha #EastCoastKin

Today's #BirdOfTheDay theme is #BestOfJune26. A Eurasian Coot chick (Meerkoet-juv.) doing its best impression of a tiny punk rocker. The orange fuzz and red head are standard issue for the first few weeks. #vogelfotografie #natuurfotografie #birdphotography #birds #SonyAlpha #EastCoastKin

Prachtige wolkenluchten vanavond maar krijgen we ook een verfrissende regenbui?

Today’s #BirdOfTheDay theme is #GreyDay any bird with grey in its plumage. Fifty shades of grey. Black-headed Gull - Kokmeeuw. #birdphotography #vogelfotografie #natuurfotografie #BirdsInFlight #SonyAlpha #EastCoastKin

A Black-headed Gull (Chroicocephalus ridibundus) in breeding plumage photographed in flight against a soft, blurred olive-brown and beige background. The bird is captured mid-wingbeat with both wings fully spread and slightly arched downward, filling most of the frame. The plumage is predominantly white with a pale grey wash across the upperwings and back. The wingtips show dark grey to black primary feathers with a thin dark trailing edge on the underwing. The bird has a distinctive dark chocolate-brown hood, a white eye-ring, a red bill, and red legs just visible at the tail. The tail is short and white with a faint fork. The bird is facing left, slightly downward, in apparent level flight. Photo by Geert Klein Breteler.

Leuk artikel over storm chaser @woutervanbernebeek.bsky.social in @trouw.nl vandaag.

Met deze temperaturen even kort afkoelen onder de buitendouche is wel echt heel lekker.

Geert Klein Breteler@geertkb· Jun 24

Goed idee.

My best #Birds&Bokeh shot might just be this one. An adult Northern Goshawk, that red-orange eye doing all the talking. Hard to look away. #BirdOfTheDay #birds #birdphotography #vogelfotografie #natuurfotografie #natuur #raptors #roofvogels #raptor #wildlife #bokeh #SonyAlpha #EastCoastKin

Close-up portrait of an adult Northern Goshawk (Accipiter gentilis) facing left. The bird fills the right half of the frame, showing a sharply detailed head and upper chest. Plumage is brown-grey on the crown and nape, with finely barred pale underparts visible on the neck and breast. The eye is a striking deep red-orange with a small black pupil. The cere and base of the hooked beak are yellow-green, the beak tip dark grey. Background is a smooth, out-of-focus green bokeh. Photo by Geert Klein Breteler.

When the sunflowers go to seed, the greenfinch shows up. #BirdOfTheDay theme #Birds&Buds. #birdphotography #vogelfotografie #natuurfotografie #natuur #birds #SonyAlpha #EastCoastKin

A female European Greenfinch (Chloris chloris) perched on a dried, seed-bearing sunflower head. The bird shows olive-brown upperparts with a yellowish-green tinge to the wing edges and pale buff underparts. It is positioned centrally in the frame, facing left, surrounded by a mix of blooming yellow sunflowers and spent flower heads in various stages of decay. The background is a soft, blurred green of trees and foliage. Natural diffuse light; wide-angle environmental composition placing the bird in context rather than isolating it.

The #birdoftheday theme is #longlegs. Young and already overdressed in the leg department. A juvenile Black-winged Stilt (Himantopus himantopus) wading in shallow water. #birdphotography #vogelfotografie #natuurfotografie #birds #SonyAlpha #EastCoastKin

Tijdens #Oerol een fijne wandeling door de duinen, echt een vorm van diep geluk. Zoveel mensen op Terschelling nu maar in de natuur vind je de stilte. 🙏
