Dipper in the Netherlands

This winter there are at least 2 White-throated Dippers wintering in the Netherlands. These birds like fast-flowing water (which we don't have a lot in the Netherlands) and in the Amsterdamse Waterleidingduinen they found enough to spent the winter. These two individuals are definitely not shy and have been photographed a lot during the past months. I haven't seen a lot of film footage though, hence my try.
