  • Montana Owl Workshop April 19-24, 2019 © 2018
    MONTANA OWL WORKSHOP APRIL 19-24, 2019 © 2018 High, wide, and handsome, Montana is the country’s fourth largest state, encompassing 145,392 square miles (376,564 square kilometers), and has one of the lowest human densities of all states; about six to seven people per square mile. Its biological diversity and variable climate reflects its immensity. Among its alpine tundra, coniferous forests, plains, intermountain valleys, mountains, marshes, and river breaks, Montana lists 433 species of birds, 109 species of mammals, 13 species of amphibians, and 18 species of reptiles. Montana also maintains about 2,080 species of native plants. Join researchers for four full days of learning how to survey, locate, and observe owls in the field. Montana boasts the largest number of breeding owl species in any state within the United States. Fifteen species of owls occur in Montana, of which 14 species breed: American Barn Owl, Flammulated Owl, Eastern Screech Owl, Western Screech Owl, Great Horned Owl, Barred Owl, Great Gray Owl, Northern Hawk Owl, Northern Pygmy Owl, Burrowing Owl, Boreal Owl, Northern Saw-whet Owl, Long-eared Owl, and Short-eared Owl. Snowy Owls are winter visitors only. Although all species will not be seen, chances are good for five to seven species, and with some luck, eight species are possible. Highlights can include Great Gray Owl, Northern Pygmy Owl, Boreal Owl, and Northern Saw-whet Owl. It’s not often the public has an opportunity to follow wildlife researchers on projects. During this educational workshop, we will meet and observe field researchers of the Owl Research Institute (ORI) who have been conducting long-term studies on several species of owls.

NATAL AND BREEDING DISPERSAL IN BARN OWLS CARL D. MARTI 1 Departmentof Zoology,Weber State University, Ogden, UT 84408-2505 U.S.A. ABSTRACT.-•Istudied dispersal of the Barn Owl (Tyt0alba) in northern Utah from 1977-96. Basedon 144 recoveriesof 2085 banded nestlings,the averagedispersal distance was 102.9 km (median = 60 km, range = 0-1267 km), occurredin most compassdirections from natal sites,but wasnot random with mountains,deserts, and the Great Salt Lake altering dispersalroutes. Dispersaldistance was not corre- lated with severityof winter weather nor population density.Among owls banded as nesdingsand re- capturedas breeders,females (N = 48) moved significantlyfarther (i = 61.4 km, median = 57.5 km, range = 0-160 km) than males (N = 34, i = 35.7 km, median = 14.7 km, range = 0.8-120 km, P = 0.015). Turnover of breeders at nest sites resulted mostly from individuals dispersinginto the study area. Only 19 (of at least 500) breedersmoved from one breeding site to another. The mean distance moved between breeding sitesof 2.3 km (median = 2.25 km) was not significantlydifferent between males and females (P -- 0.9), but more females (16) than males (3) made these moves.Eight of the adults that shifted breeding sitesdid so in the same year either after a failed first attempt (2) or to produce a secondbrood (6).

  • BARN OWLS (Tyto Alba) in PENNSYLVANIA
    CONSERVATION POTENTIAL OF BARN OWLS (Tyto alba) IN PENNSYLVANIA by Alicia Burtner Dr. Curt Richardson, advisor May 2010 Masters project proposal submitted in partial fulfillment of the requirements for the Master of Environmental Management degree in the Nicholas School of the Environment of Duke University 2010 ________________________________ Dr. Curtis Richard, MP advisor ABSTRACT Though once prolific, the barn owl (Tyto alba) is now considered vulnerable in Pennsylvania and vulnerable-to-critically imperiled in all surrounding states. Barn owls are charismatic animals. They are wide-ranging generalists, so they are seldom the target of species-specific conservation efforts. Barn owls thrive in open habitats, so their North American extent expanded extensively in the early 1900 with the increased deforestation brought by intensified farming. Farming practices in the northern range of the Unites States subspecies (T. alba pratincola) are changing, and barn owl populations appear to be responding. Across Pennsylvania, open pastures are being replaced by smaller, row crop fields that have the decrease barn owl hunting habitat. With the exception of a several nesting box companies, few people are actively working towards conservation of barn owls. Statistically accurate descriptions of their specific habitat requirements are rare as a result of their wide range and general disinterest in studying the species. Radio-transmitted data from 16 barn owl fledglings released from Pittsburgh, Pennsylvania, was used to determine preferred habitat and climatic conditions. Owl dispersal paths spanned the eastern United States. Dispersal patterns consisted of bursts of rapid dispersal as well as heavy use of home ranges of 320 km2. The most heavily used point within each established home range used by a successful owl was compared to locations of mortalities using envelope, generalized linear, and classification and regression tree spatial models.

McCracken, Bird Studies Canada ON BEHALF OF THE Ontario Barn Owl Recovery Team FOR THE Recovery of Nationally Endangered Wildlife (RENEW) Committee December 2002 Disclaimer This document is the National Recovery Plan for the Barn Owl (Tyto alba) - Ontario population. It has been prepared on behalf of the Ontario Barn Owl Recovery Team (OBORT) by Bernt Solymár of EarthTramper Consulting Inc. and Jon McCracken of Bird Studies Canada, with the advise and input from Recovery Team members, to define recovery actions necessary to protect and recover the species and its habitat. It does not necessarily represent official positions of agencies and/or the views of individuals involved in the development of the plan. The goals, objectives, and recovery actions identified in this recovery document are subject to the priorities and budgetary constraints of participating jurisdictions and organizations, as well as modifications to accommodate new objectives or findings.
