Foreground, behive; background, stork on nesting platform. At least, I think it’s a stork but maybe different migratory birds use those platforms at different times. That’d be a smartly-adaptive Dutch approach to supporting migratory bird populations in the midst of probably the most famous park in the nation…
I’m reasonably confident these are white storks, and I believe their presence on the platform also answers questions my cousin Maria (hi, Maria!) asked about similar platforms which appeared in photographs from other posts late last year. I can’t state with certainty that all such platforms are intended for or solely used by storks, but I expect they’re intended for and used more by storks than any other type of bird. You and I wondered if it was maybe ospreys, and I’m afraid I’ve not yet gotten a book that’ll tell me which birds ply the forests and waterways of this corner of Europe so I’m not even sure if ospreys are found here – haven’t seen any myself, yet, but I’ve not really been looking yet. I am confident storks do, and this is the first pair I’ve seen. They really do clack their bills and communicate with each other a lot! If the left-hand photo below, you can sort of make out this platform in the middle near the top of the photo.
