I'm on a visit to Copenhagen and I've just seen a large flock (c 100) of large birds circling over the city centre. They were too high to make out much in the way of markings. My initial thought was White Stork but I don't think they come this far north. Consulting the books I'm wondering if Spoonbill is more likely. Or cranes? Anyone know which species would occur in such numbers this far north at this time of year?
