Title: Extra-pair copulation and extra-range movements in Flammulated Owls

Author: Reynolds, Richard T.; Linkhart, Brian D.;

Date: 1990

Source: Ornis Scandinavica. 21(1): 74-77.

Publication Series: Scientific Journal (JRNL)


We report an extra-pair copulation (EPC) in the Flammulated Owl (Otus flammeolus), the first in strigiforms, and document 21 cases of extra-range movements (ERMs) in this species. Extra-range movements occurred throughout nesting with both sexes participating: males anytime during nesting and females only after their young fledged. Males appear to make ERMs to gain EPCs and later to evaluate resources and the status of males in other areas, whereas females may be assessing the success of nests in adjacent ranges to judge the quality of potential future mates.

Keywords: Flammulated Owl, Otus flammeolus, extra-range movements (ERMs)
