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 #Birds&Bugs any bird and bug in one capture.

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.

Good morning everyone.
The #BirdOfTheDay theme today is #birdsandberries.
Bohemian Waxwings feasting on rose hips and dark berries, a classic winter pairing where colour and behaviour come together.

Today's #BirdOfTheDay theme is #Reflections. Two Black-tailed Godwits share a quiet moment at first light, their reflections stretching across the calm water.

De zeearend, 20 jaar in Nederland en nu al 50 paartjes. Geweldig!

De zeearend viert feest: jarig en succesvoller dan ooit
In 2006 broedde de zeearend voor het eerst in de Oostvaardersplassen. Twintig jaar later groeit de populatie nog altijd.
