I studied reproduction of the Barn Owl (Tyto alba) in irrigated farmlands of northern Utah for 16 years documenting 391 nesting attempts. Most Barn Owls began nesting at one year of age and produced one brood per year. The owls rarely produced second broods or replaced failed first clutches. Complete first clutches averaged 7.17 eggs (n = 275). Replacement (x = 5.81, n = 16) and second clutches (x = 5.79, n = 19) were significantly smaller than first clutches, but first (X = 5.45) and second… Expand
