When I embarked on my 2025 Rotterdam Big Year little did I realise how hard it was going to be. Turns out you need full dedication and a lot of stamina to finish a Big Year successfully, even in a small area like Rotterdam. I learnt a lot about myself and about birding. Since the readers of 10000birds don’t care about my inner stirrings I will focus on the birds. Even Canada Goose trumps my psychological insights, I admit.

This post’s title – a blatant rip-off of a much better article – gives away the year’s result: I did not see my target 200 birds in Rotterdam. Turns out that spending significant time in Malaysia, Indonesia, Timor-Leste, and the United States is not good for seeing summer migrants in some Rotterdam marsh. The universe may be indifferent to my failure, but it granted me Jeff Kingma who got me this picture of a Chestnut-capped Laughingthrush while we were birding Bukit Fraser.

Even when birding in the right season, I managed to do it outside the municipal borders of Rotterdam. Still, the Sedge Warbler I saw in De Groene Jonker was nice.

All in all an interesting year; I have seen some really marvelous birds, even rather exotic ones, like Harlequin Duck. Most importantly, I thoroughly explored my home town’s green spaces.














The secret of success is to set yourself an achievable target. Aim at 100 this year Peter. Must admit I’m greatly impressed by the harlequin, even if it was a rather dull female. (The drakes are stunners).
