The extremely popular Ferruginous Duck / Hvitøyeand Aythya nyroca, which was present on the 6th May, proved to be as popular on the 7th with many visiting birder's getting the chance to add a new Norwegian species or even a lifer to their lists. Dissapointingly, the duck was not seen at all on the 8th at Snekkestaddammen although extensively looked for. Amazingly, another adult male Ferruginous Duck (or could it have been the same), was found on a small pond at Sandefjord (ca. 36 km to the south) on the 8th. This duck was only seen by a handful of selected observers but otherwise suppressed. No Ferruginous Duck was reported seen on 9th May, but on the 10th May a local birder again found the Holmestrand duck at the original locality Snekkestaddammen. The chances of the same duck moving between both localities would seem rather unusual and the possibility that there have been two individuals rather surprising, considering there are only eleven earlier accepted records of this species. An early morning visit to Snekkestaddammen on 11th May found the Ferruginous Duck following a male Mallard which suddenly swan out of the vegetation in front of where I was standing, and a series of images taken. The duck then swam into the vegetation again and disappeared but reappeared thirty minutes later partially hidden in the duck's favorite area. Considering these observations, it will be interesting to see if the Norwegian rare birds committee (NSKF) consider one or two ducks have been involved.
