Rock Wren

Erika and I saw several Rock Wrens during our July stop-over at the Badlands National Park in South Dakota. The birds gave us a mini-course in Rock Wren eating habits. Studies in Utah have compiled a list of 13 insect orders being eaten by Rock Wrens. Lowther et al. (2000) that Rock Wrens mostly eat insects, mainly crickets, grasshoppers, ants, leaf-hoppers, bugs and beetles. We concur. The bird in the first photo seems to be consuming a grasshopper or cricket. The second wren has a butterfly or moth caterpillar, an order known to be on the Rock Wren’s menu.
