Abstract During the past century, Barred Owls (Strix varia) expanded their range from forests east of the Great Plains to forests throughout most of central and western North America. Here in Part I, I map more than 12,500 records of Barred Owls in their expanded range from the earliest records to the present, draw the species' distribution in its expanded range and infer the general timing and flow of the range expansion. Evidently, Barred Owls originally traveled across the northern Great… Expand

Range Expansion of Barred Owls, Part II: Facilitating Ecological Changes
TLDR
Overall, it appears the historical lack of trees in the Great Plains acted as a barrier to the range expansion and recent increases in forests broke down this barrier and allowed Barred Owls to move westward. Expand
Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon
The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl andExpand
The Journal of Wildlife Management
Barred owls (Strix varia) are forest‐dwelling owls, native to eastern North America, with populations that expanded westward into the range of the spotted owl (Strix occidentalis). Barred owls exertExpand
Killing Barred Owls to Help Spotted Owls II: Implications for Many Other Range-Expanding Species
TLDR
Information is presented concerning how frequently range expansions of North American birds and other factors may precipitate similar management issues in the near future, probability that range expansions will continue, increases in number of listed species, and further documentation of negative effects between species are presented. Expand
Demographic response of northern spotted owls to barred owl removal
TLDR
The results from this first experiment demonstrated that lethal removal of barred owls allowed the recovery of northern spotted owl populations in the treated portions of the study area, and could be the foundation for development of a long-term conservation strategy for northern spotted owls.

Transient dynamics of invasive competition: barred owls, spotted owls, habitat, and the demons of competition present.
TLDR
A strong, negative association between Barred Owls detections and colonization rates and a strong positive effect of Barred Owl detections on extinction rates of Spotted Owls are observed. Expand
Review of the effects of barred owls on spotted owls
Barred owls (Strix varia) are forest‐dwelling owls, native to eastern North America, with populations that expanded westward into the range of the spotted owl (Strix occidentalis). Barred owls exertExpand

ABSTRACT Protected lands like national parks are important refuges for threatened and endangered species as environmental pressures on wildlife and their habitats increase. The Northern Spotted OwlExpand

Killing Barred Owls to Help Spotted Owls I: A Global Perspective
TLDR
A precedent-setting removal study in which as many as 2150 to 4650 Barred Owls would be killed would result in the death of 36 times more raptors than in all other conservation-based projects combined in the United States and its territories, and 84 times more Raptor deaths than in the largest ongoing effort worldwide.

STATUS AND DISTRIBUTION OF THE BARRED OWL IN MONTANA
TLDR
This 1st summary of the barred owl (Strix varia) colonization of Montana was constructed from a review of the literature, and it appears likely this species will continue to colonize both north to south and east to west. Expand
DISPERSAL MOVEMENTS AND SURVIVAL RATES OF JUVENILE MEXICAN SPOTTED OWLS IN NORTHERN ARIZONA
TLDR
Estimates differed significantly between years and confidence intervals were wide, suggesting that longer-term studies of lame numbers of owls will be reauired to obtain accurate and precise estimates of juvenile survival. Expand
Natal and breeding dispersal of northern spotted owls
TLDR
Although statistical tests of dispersal direction based on all owls indicated that direction of natal dispersal was non-random, the mean angular deviations and 95% CI's associated with the samples were large, and r-values were small, which lead it to conclude that significant test results were the result of large sample size and were not biologically meaningful.
