This afternoon I had a male Common Goldeneye at Madrona Marsh. It is shown as "first seen" in eBird. It was first seen about here (33.828497, -118.344163) and then flew due south, low. So could still be lurking around. There have been small groups of mixed swallows around Long Beach and the South Bay in the past few days.
The site has a lot of water so should be good for a while. Tomorrow's hours are 10-5.
