Mitochondrial DNA control region sequences of spotted owls (Strix occidentalis) allowed us to investigate gene flow, genetic structure, and biogeographic relationships among these forest-dwelling birds of western North America. Estimates of gene flow based on genetic partitioning and the phylogeography of haplotypes indicate substantial dispersal within three long-recognized subspecies. However, patterns of individual phyletic relationships indicate a historical absence of gene flow among the subspecies, which are essentially monophyletic. The pattern of haplotype coalescence enabled us to identify the approximate timing and direction of a recent episode of gene flow from the Sierra Nevada to the northern coastal...

We conducted a survey of spotted owl (Strix occidentalis) ectoparasite richness by examining live and museum specimens of the three subspecies of spotted owl. Seven ectoparasite species from five arthropod orders were collected. A tick (Dermacentor occidentalis), a mite (Euschoengastia sp.), and a flea (Opisodasys vesperalis) were collected, but were presumed to be accidental strays from prey. Strigiphilus lice were found on all the subspecies of spotted owl, while the louse Kurodaia magna was only collected from the northern spotted owl (S. o. caurina). The hippoboscid fly Icosta americana was found on the California spotted owl (S. o. occidentalis); this species had previously been well documented in the northern...
