Flowering barrel

All the barrels are flowering together. There was a gang of swallows around yesterday and today, dark on top and white below, dark around the eyes with a white cheek-patch. From the loud raucous whistling call I think they are Northern Rough-winged Swallows, although they have more white extending up the cheek than the picture in the book shows. The other possibility from the call was Violet-green Swallows, but these ones did not have the white above the eye. In general lots of birds calling this morning.
