Species Name: Asio otus
Species Distribution in Massachusetts
Federal Rank: None
Massachusetts State Rank: Special Concern
Sufficiently rare and secretive that their precise habitat requirements in Massachusetts are not fully understood. Generally, they prefer dense coniferous or mixed forests or groves close to fields or other open areas suitable for foraging when they are nesting.
Threats to Survival
Determining the breeding population has proven to be extremely difficult, with fewer than 10 breeding confirmation occurring the past 35 years. It’s possible it is more abundant than it is thought, but with the information available it is a rare breeding species.
Actions Recommended to Ensure Survival
Massachusetts is the at the edge of its range, so it is widely believed that the species never attained a widespread breeding population in the state.
