We were unable to observe which particular species of small bird constructed this nest, with a near-perfect side entrance into the dwelling, but whoever it was had a natural instinct for home-building. The nest rests about ten feet above the desert floor in a thorny environment that might offer protection against predators. The shelter is located next to an arroyo with somewhat lush flora--Littleleaf and Three-Leaf Sumac, mesquite trees and sage, etcetera--that attract insects which provide food for the birds.
