The Tenth Report of the Maine Bird Records Committee (hereafter ME-BRC or the committee) summarizes 96 reports involving 58 species, including two distinctive subspecies, that were evaluated and decided during 2020. The committee accepted 77 records for an acceptance rate of 80%. Although many reports were recent, the years of occurrences ranged from 1903 to 2020.
No new species were added to the state list, but the committee accepted first state records of two distinctive subspecies: Greenland Dunlin (Calidris alpina arctica) and Great White Heron (Ardea herodias occidentalis). Review and rejection of a 1903 report of Whooper Swan that had been placed provisionally on the state list dropped the total number of documented species on Maine’s state list to 463. However, historical reports of fifteen additional species that had been placed provisionally on the state list were reviewed and accepted. The official list of bird species recorded in Maine, our review procedures, and the list of members can be found at the committee’s website: <http://sites.google.com/site/mainebirdrecordscommittee.>
Records in this report are grouped by species; records accepted and those not accepted are listed within the same species account. Each record provides the location, county (italicized), date(s) of occurrence, names of observers or contributors, and committee record number. Documentation was provided by the observers listed or, in some cases, was obtained from publicly published websites. All reviewed materials and member comments are archived. If known, the names of finders are listed first and separated from other names by a semicolon. Photographic, video, or audio evidence reviewed is denoted by a dagger (†); written notes are denoted by an asterisk (*). As always, the committee strongly encourages written submissions even when there are photographs. Species accounts follow the current taxonomic classification and sequence adopted as of 2020 by the American Ornithological Society (list available at <http://checklist.americanornithology.org/taxa/>).
