Spring arrival of flammulated owls to a 452-ha area in Colorado occurred in early May. Each year, 4-6 territories were occupied by pairs and 2-3 territories by unpaired males. Clutch size was 2.7 eggs, incubation was 22 nights, brood size was 2.4 young, and young were in the nest 23 nights. Owlets dispersed in late August and adults in early October. The affinity of flammulated owIs for old yellow pine forests stems from the abundance of nest cavities, the structure of the trees and stands, and the arthropods found in these forests.
