Visiting Swansons Nursery’s annual Reindeer Festival last week, I drew a few vignettes of the featured stars, Dasher and Blitzen. These incomplete views had to be done quickly because of the reindeers’ constant moving about. This exercise reminded me of how drawing from observation sharpens our visual acuity and helps us notice often subtle traits or characteristics. For example, I had always assumed that deer antlers grew symmetrically, but these reindeer had antlers that were not symmetrical at all. In doing some research, I came upon what biologists call fluctuating asymmetry in deer antlers, which can be caused by a variety of genetic and environmental stresses. In addition, these reindeer had a multipronged tine extending over their foreheads on one antler but not the other. This extra blade was supposedly used as a snowscraper!
