Red-breasted Nuthatches are one of the smallest songbirds, only about a half an inch longer than an Anna’s Hummingbird. And, they are very fun to watch. as they forage, especially when headed downhill on a tree trunk. According to Sibley Birds, the White-breasted Nuthatch, the Red-breasted’s larger cousin, commonly is seen in this position while the Red-breasteds are most commonly seen perched on branches. We stopped along Arkola Road in Sax-Zim Bog at one of the feeding sites tucked into the edge of the woods. I took quite a few shots of this Nuthatch perched, but when it headed down the trunk of the tree, I laid on the shutter release, hoping to get it flagged out, beak almost perpendicular to the tree trunk, as in this image. I think of this as classic Nuthatch.
