The trails leading to the Sunnyvale WPCP ponds are open again (construction is still ongoing for the path to A4, which is only accessible via a detour). Many of the usual suspects were present - a dozen COMMON GALLINULES, a single BLUE-WINGED TEAL in the channel to the east of the East Pond, a few CINNAMON TEAL mixed in.
Most interesting to me was a partial leucistic NORTHERN SHOVELER (picture attached) in the channel to the east of the West Pond <https://goo.gl/maps/a3ECjTj4mSRQuuWS6>. It was cool to see a Northern Shoveler with male plumage and that bright orange bill. Looking at other examples of leucistic Northern Shovelers, this seems to be common - suggesting there's some dark pigment produced by the males but that the "base" color of the bill is orange. I'd be curious if anybody knew more about this mechanism or could correct me if I'm wrong.
