De oranje erehaag voor Xandra Velzeboer staat symbool voor deze Spelen. Volgens mij staat Schulting er telkens niet bij, klopt dat @kickhommes.bsky.social?

Xandra Velzeboer is sinds maandag net als Jens van ’t Wout tweevoudig olympisch kampioen. Hoe komt die ploeg zo goed?

Head down, tail up. This Pied Avocet was fully focused on probing the shallow water, completely unaware that it was unintentionally contributing to today’s theme.

Today’s #BirdOfTheDay theme is #Portrait , a portrait capture of any bird.

A Northern Gannet portrait with that unmistakable piercing blue gaze.

Deep in the valley of the Hoëgne, where water carves its way through layered rock and moss.
I used a long exposure here to soften the rushing current and let the stream draw its own lines through the frame.

A split second of pure precision.
This Caspian Tern (Reuzenstern in Dutch) had just surfaced and tossed its catch into the air, perfectly timed before swallowing it mid flight.

Today's #BirdOfTheDay theme is #StareDown, birds looking right at you. This Common Kestrel locks eyes from its perch, perfectly still and razor focused, as if weighing up whether I am worth its attention.
