Several species of screech-owls are found in North and South America, including 3 in the United States. All three (whiskered screech-owl from the southwest, eastern screech-owl from eastern North America, and western screech-owl from west of the Great Plains) are very similar to each other in appearance and habits. All are closely related to the Scops owls of Africa and Eurasia. One of these birds -- sitting in a huge old sycamore tree -- was in Two Trees Canyon in Riverside, California; the others were in a grove of cottonwood trees along the Rio Grande in San Antonio, New Mexico.
