The Black-throated Gray Warbler was a drive up bird at Heritage Square, Emeryville. I pulled into the parking lot for Bucci's on Hollis st 59th in Emeryville and the warbler popped up in front of my car. I watched through the wind shield as it foraged in the sunlight 8 feet away. It took off and I refound it in the low plants near the office building in the back.
