While in Northwest Arkansas on Tuesday, I decided to search for American Tree Sparrows. These small sparrows have gray faces with rusty caps and eyeline marks along with a bicolored bill.

While found each year in Arkansas, the American Tree Sparrow is not a common sparrow you find just anywhere within the state. Their population is in steep decline. It took us a bit, but we eventually ran across four of these sparrows as they steadily made their way through a brushy area. One neat fact I learned through All About Birds is the American Tree Sparrow has to eat 30% of its weight each day.

We found these sparrows – as well as lots of Eastern Bluebirds – at the Healing Springs Natural Area maintained by the Arkansas Natural Heritage Commission since 2020. I wasn’t sure what to expect from the natural area. It is located within the Ozark Highlands of the Springfield Plateau Ecoregion where Oak-hickory forests, oak-hickory-pine forests and, before the 19th century, savanna or tall grass prairies are common and maintained by fire. The small entrance to the natural area from the highway is just large enough to park about two vehicles. A locked gate and fence keeps people from driving into the natural area, which at first sight, contains several large fields that are being restored to native grassland and woodland habitat.

The natural area consists of several large fields separated by high fences with no gates so you can wander for nearly a mile to the springs and spring-fed streams at the back of the property. These springs and spring-fed streams support several fish and crayfish species of conservation concern, including the Arkansas Darter and Least Darter. Both are very rare to Arkansas and require a specific habitat type that is disappearing.

We couldn’t find a map of the property so we initially walked a wooded path the width of the natural area, before traveling further back into the natural area in search of the springs. We weren’t too impressed with the place until we got further back into the area where we began seeing white-tailed deer and an abundance of birds, including our target bird – the American Tree Sparrow. One surprise was the rusty blackbirds discovered in a tree near water.
