Many years ago I remember seeing 23 piebald deer in a winter wheat field. This was in Newfield, NY (near Shelter Valley Rd). This was in mid March and the snow was just leaving the hills. I remember the time of year because I was there to check on the rainbow trout run in Cayuga Inlet. Anyway, there were also 100+ hungry brown whitetails in the same field, but they did NOT associate with the piebald deer. I watched them for over 30 minutes and the two groups avoided each other. I imagine that's not the case during the rut!
