Accepted by the ME-BRC on 7 Sep 2019 (8-1) after three rounds of voting. Here are my notes from that round: Establishing the identification of this bird was very educational but the question of origin seemed to delay committee review. In 2011, the NYSARC voted to add Trumpeter Swan to their state list based on a “steady self-colonization” over the “last 10-15 years” (nybirds.org/KBsearch/y2013v63n3/y2013v63n3p170nysarc.pdf). A May 2014 Vermont record was accepted, adding the species to that state list, and Massachusetts accepted their first from a May 2018 record (http://www.maavianrecords.com/Annual-Reports/22nd.pdf). New Hampshire seems poised to add their April 2019 (and continuing) bird too. I am of the opinion that the Maine bird should be treated as a vagrant, presumably of this population that the NYSARC had considered established by 2011, and add Trumpeter Swan to Maine’s list.
