A new species in the valley

It seems like natural things - animals, flowers and trees, birds, water - sort of jump out at me and today I spotted these two in a bean field close to home. I've seen deer crossing in that area and I wondered if it could be albinos. At a distance, I couldn't tell what they were so I went to get my camera and binoculars. The two hadn't gone far when I returned but I could see gentle movement, the flash of a wing being spread, maybe picking at the beans. A closer look with binoculars and my camera zoom didn't help me identify them. Anybody got any ideas?
