With the first snow, winter has now officially started. A perfect day to go to the coast I thought, but after about 2 hours (in which I managed to read 10 c-ringed Herring gulls, 8 Belgian and 2 Dutch birds) it was really getting too cold to stay there, so I decided to go and watch a flock of northern Long-tailed tits (Aegithalos caudatus caudatus) that has been hanging around for some weeks in Nieuwpoort (a major invasion of this attractive subspecies is taking place this autumn). Also there where 2 more ringed Herring gulls. Later on, a search for the wintering White-tailed eagle only resulted in two flocks of Grey partridge close to the car.
