Western and Eastern Screech-Owls are two closely related Screech-Owl species with converging ranges along the Missouri River in Montana. Both species are listed as Potential Species of Concern, and the Western Screech-Owl is listed on Montana's Species of Greatest Inventory Need List. The most recent Winter Breeding Owl survey occurred in 2014, targeting fourteen owl species including the Western and Eastern Screech-Owls. Both owls are small, secretive, nocturnal species with heightened vocal activity in the breeding season (February-May). To assess the presence of the species, surveyors will use callback recordings to evoke a vocal response from present owls.
Both Screech-Owl species nest in tree cavities, depending on old-growth trees in riparian areas, cottonwood groves, and conifer forests. With the increase in infrastructure in the last decade and the lack of recent population data on these two owl species, surveying efforts would contribute to a further understanding of how the populations are affected by habitat loss. Citizen science is vital for this survey because it allows researchers and land managers to receive more data on where, when, and how many owls are in specific locations. Answering these questions allows for conservation and land management decisions based on scientific research.
This survey will take place between March 1st-April 30th.
