I decided to visit the Milnerton Sewage Works (aka Potsdam Waste Water Treatment Works) this morning as I had not been there for a long time and nobody really birds the area, so anything could be lurking there without anyone knowing about it. The strangest sighting of the morning was a female North American Wood Duck Aix sponsa which was almost certainly an escapee from somewhere. With this birds home range restricted to North America and perhaps getting as far south as Mexico, it is extremely unlikely that a genuine vagrant would ever turn up in South Africa and they are also extremely popular in local waterfowl collections. I also finally caught up with White-winged Tern and Intermediate Egret for my photographic year list. The egret has certainly become decidedly more uncommon around Cape Town in recent years. The only other excitement of the morning was an African Harrier Hawk over the sewage works, but it was just too far to get any sort of photo of. This is certainly the first time I have seen this species in this area. They were virtually unknown around the Cape Town area when I was growing up in the area, but they have certainly increased in numbers locally in the last few years and are now resident on the southern Peninsula and regular around the Durbanville area as well, but I have not heard of previous records around the Table View area.
