It is WW or WR, hard to tell from the pics, but it doesn't much matter from a deer's perspective; cereal is cereal. While deer will use the seed heads on occasion, they are not particularly attractive. Cereal is the most attractive when it is young and supple. When planted for fall, deer seem to be all over it when it 3" or so tall. It doesn't provide much summer food value for deer. WW and WR overwinter and provide some early food when they are still small in the spring. They quickly loose their attraction when other native foods green-up. You can plant cereal in the spring for food later into spring. Oats are often used for spring planting as they generally don't overwinter and WW and WR are more often planted in the fall for hunting season attraction.
