Twenty-first Report of the Massachusetts Avian Records Committee

Sean M. Williams and Jeremiah R. Trimble

One species was added to the official state list, Common Greenshank, and two were removed, Thayer's Gull and Monk Parakeet. The official state list of Massachusetts currently stands at 501.

Tim Spahr and Brian Harris unearthed a photograph from the depths of the internet labeled as a Greater Yellowlegs, taken in Gloucester on December 8, 2014. The photographer confirmed the date and location of the photograph, which was also supported by metadata. The photograph indeed was a Tringa shorebird, but had dull yellow-green legs instead of bright yellow legs, a mostly white face with a large white gap between the bill and the dark coloration on the forehead, and uniform scapular feathers. The identification was clearly Common Greenshank. This record is not only a first for Massachusetts, but represents one of very few records in eastern North America. Coincidentally, only two weeks after this post hoc discovery, a Common Greenshank was found in New Jersey in late October 2017.

Black-backed Oriole, Putnam Hill Road, Sutton, 5/7/2017. Photograph by Margaret Bowden.

On May 7–8, 2017, a homeowner in Sutton noticed a bright orange oriole at their feeders that was not a Baltimore. They circulated photographs to some local birders, who were astonished to see it was a Black-backed Oriole, an endemic species of central Mexico! Not only that, but certain unique facial markings are identical to that of an individual that visited some feeders at Sinking Spring, PA in January-April 2017. It is a near certainty these two sightings are of the same individual. The committee unanimously rejected this record on the first round on the grounds of provenance. Black-backed Oriole is an altitudinal local migrant, and has not been shown to occur naturally outside of Mexico. In addition, the species is found in the caged bird trade to at least some capacity. The committee was not convinced that a wild origin was significantly more likely than a captive origin, so it decided to be cautious. Many more details and photos can be found on our website at <maavianrecords.com/black-backed-oriole/>.

This report treats records of two rare northern owls that both were identified originally as their southern congeners. During the Super Bowl of Birding XIV hosted by Mass Audubon, a small roosting owl was photographed and identified as a Northern Saw-Whet Owl. The photos, however, later revealed a Boreal Owl. Despite extensive searching, the owl was never relocated after the initial observation. In the Nungee Swamp in Hampshire County, a foraging owl in an open field was photographed and identified as a Barred Owl on eBird. Weeks after the fact, Brian Rusnica came across the eBird report of a Barred Owl and alerted the birding community to the apparent presence of a Great Gray Owl. Once again however, this owl was never refound.

Other highlights in the report include a Magnificent Frigatebird that was photographed during a whale watch at Stellwagen Bank in June 2017; eight Ross's Goose reports; four Mew Gull reports; and seven Painted Bunting reports. Ross's Geese clearly have exploded into the Northeast, with at least 19 total records in the past 10 years in Massachusetts alone, and only three scattered records prior to that.

During the annual meeting in December 2017, the committee decided to remove two species from the state list. Following recommendations of the American Ornithological Society, the committee delisted Thayer's Gull as a full species and instead now considers it a subspecies of Iceland Gull (Chesser et al. 2017). Furthermore, the committee removed Monk Parakeet from the official state list since no records of this species have received any official action from the committee. The MARC would welcome any submissions of older records of this species from the state.

The website of the committee received a dramatic renovation, with several new features added such as a report form and a searchable database of all accepted records. Visit here: www.maavianrecords.com.

The 2016–17 roster of MARC voting members included Nick Block, Ian Davies, Mark Faherty, Jessica Johnson, Wayne Petersen, Tim Spahr, Ryan Schain, Scott Surner, and Jeremiah R. Trimble (chair). Sean Williams served as secretary.

In this truncated report, we present basic statistics for each record of each species or taxon covered: the record number, count of individuals, where and when the bird was seen, and who submitted evidence. We also indicate if the evidence provided was photographic (ph), video (v), audio (au), or a written submission (†). As always, the committee strongly encourages written submissions even where photographs exist. When known, we try to credit the discoverer with an asterisk (*), especially if he or she has supplied evidence. The statistics in brackets for each species or taxon show the number of individual birds accepted through records in this report, followed by the total number of MARC-accepted individual records for that species.

Species taxonomy and nomenclature follow the seventh edition of the American Ornithological Society (AOS, recently changed from American Ornithologists' Union) Check-list of North American Birds (AOU 1998) and its supplements (Chesser et al. 2009, Chesser et al. 2010, Chesser et al. 2011, Chesser et al. 2012, Chesser et al. 2013, Chesser et al. 2014, Chesser et al. 2015, Chesser et al. 2016, Chesser et al. 2017).

The list of species reviewed by the MARC (the Review List) is available at <www.maavianrecords.com>. Please check out the full Review List and send us any evidence of new or old records you may have—even in this Information Age we often do not receive sufficient information for many records.

2017-013: 1 at Ludlow, MA, Hampden, June 2017 [courtesy of Jean Yobst-Fournier (ph)]. Amazingly, a Brown Booby was perched on the guard rail of a bridge under construction in Ludlow. A passerby photographed and posted it to a local bird photography Facebook group, where it quickly gained attention.

2017-054: 1 at Nauset Marsh, Orleans to Pleasant Bay (lastly on South Beach), Chatham, Barnstable, 06/17/2017 to 07/19/2017 [Blair Nikula (ph)]

Common Greenshank (Tringa nebularia) [1, 1]

2014-072: 1 at Gloucester, Essex, 12/8/2014 [Stan Deutsch* (ph), Tim Spahr, Brian Harris]

Franklin's Gull (Leucophaeus pipixcan) [4, 17]

2017-046: 1 at Race Point, Provincetown, Barnstable, 6/2/2017 to 6/15/2017 [Blair Nikula* (ph), Joe Bourget* (ph)]

2017-047: 1 at Race Point, Provincetown, Barnstable, 6/16/2017 to 6/17/2017 [Peter Flood]

2017-048: 1 at Race Point, Provincetown, Barnstable, 6/7/2017 [Blair Nikula*, Peter Trimble* (ph)]

2017-061: 1 at Race Point, Provincetown, Barnstable, 6/24/2017 to 6/29/2017 [Peter Flood* (ph)]. How many Franklin's Gulls were present at Race Point in June 2017? Apparently no fewer than four, as is evident by varying molts of well-photographed birds. Historically, June has not been a month typically associated with Franklin's Gull records in Massachusetts.

Mew Gull (Larus canus) [4, 12]

2017-003: 1 at Lynn Beach, Nahant, Essex, 2/25/2017 to 2/28/2017 [John Quigley* (ph), Joe Bourget (ph), Dan Prima]

2017-005: 1 at Race Point, Provincetown, Barnstable, 3/26/2017 [Blair Nikula* (ph)]

2017-006: 1 at Race Point, Provincetown, Barnstable, 4/15/2017 [Will Sweet* (ph)]

2017-007: 1 at Race Point, Provincetown, Barnstable, 4/15/2017 [Alan Kneidel*, Nathan Marchessault* (ph)]. Lightning struck twice on April 15, 2017 at Race Point. Will Sweet was birding independent of Alan Kneidel and Nathan Marchessault and both parties reported a Mew Gull. Of course, the logical conclusion would have been that the same bird had been sighted twice. However, photographs revealed two completely different individuals, one a clean, breeding-plumaged "European" Mew Gull and a streaky-headed "Kamchatka" Mew Gull!

White-winged Dove (Zenaida asiatica) [1, 24]

2017-043: 1 at Schoolhouse Pond, Chatham, Barnstable, 6/2/2017 [James Junda* (ph)]. Chatham seems to be a mecca for rare doves of Massachusetts.

Great Gray Owl (Strix nebulosa) [1, 7]

2017-002: 1 at Nungee Swamp, Williamsburg, Hampshire, 2/22/2017 [David Pritchard* (ph)]

Boreal Owl (Aegolius funereus) [1, 9]

2017-001: 1 at Ipswich River Wildlife Sanctuary, Topsfield, Essex, 1/28/2017 [Andrea Bean* (ph)]

Boreal Chickadee (Poecile hudsonicus) [Added to review list 2017; one record since then]

2017-032: 1 at 16 Bonny Lane, Peru, Berkshire, 1/2/2017 to 2/5/2017 [Richard Guthrie* (ph)]. This species has become very scarce in Massachusetts, with only a couple records in the past 10 years. The previous record was a bird that stayed for a few days in Squantum in November 2010.

Smith's Longspur (Calcarius pictus) [1, 4]

2017-004: 1 at Bear Creek Sanctuary, Saugus, Essex, 3/15/2017 to 4/9/2017 [Geoff Wilson* (ph)]. A Smith's Longspur was present at Bear Creek Sanctuary for the second year in a row. It is entirely up to speculation as to whether there are one or two individuals involved. The first record occurred 12/21/2015 to 1/20/2016.

Harris's Sparrow (Zonotrichia querula) [1, 12]

2017-060: 1 at Otis Avenue, Dalton, Berkshire, 11/25/2016 to 5/11/2017 [Gael Hurley* (ph)]

Golden-winged Warbler (Vermivora chrysoptera) [Added to review list 2017; one record since then]

2017-012: 1 at Quabbin Park, Belchertown, Hampshire, 5/31/2017 to 06/03/2017 [Larry Therrien* (ph)]

Painted Bunting (Passerina ciris) [7, 23]

2016-020: 1 female at Melrose Highlands, Melrose, Middlesex, 11/27/2016 [Devin Hefferon* (ph)]

2017-038: 1 male at 229 Brick Hill Road, Orleans, Barnstable, 2/5/2017 to 04/14/2017 [Sue Finnegan (ph)]

2017-055: 1 female at Madaket, Nantucket, Nantucket, 05/12/2017 [Trish Pastuszak* (ph)]

2017-056: 1 male at Mountain View Drive, Huntington, Hampshire, 5/1/2017 to 5/2/2017 [Larry Therrien (ph)]

2017-057: 1 at Jewett Road, Sterling, Worcester, 5/25/2017 [Marion McDermott*]

2017-058: 1 at Blantyre Road, Centerville, Barnstable, 12/17/2016 to 12/19/2016 [Linda Iafrate (ph)]

NOT ACCEPTED

Magnificent Frigatebird (Fregata magnificens)

2017-016: 1 at Salisbury Beach, Salisbury, Essex, 6/13/2017. This report potentially could have pertained to the same individual as 2017-015, although the members felt that the photograph was inconclusive and the description was too brief to rule out other frigatebird species, and potentially other seabirds.

Eurasian Collared-Dove (Streptopelia decaocto)

2017-017: 2 at Salem, Essex, 6/17/2017 to 6/24/2017. It is difficult yet critical to evaluate certain features on Streptopelia doves, which include the color of the back and primaries, the color of the undertail coverts, and if the black coloration on other outer vane of the outer rectrix extends more posteriorly than the black coloration on the inner vane. These features are necessary to rule other the similar Streptopelia doves and their intergrades, which are common pets in the caged bird trade. Unfortunately, this report did not include those details and, therefore the committee determined that the supporting documentation for this identification was inconclusive.

Bicknell's Thrush (Catharus bicknelli)

2017-010: 1 at Marblehead Neck Wildlife Sanctuary, Marblehead, Essex, 5/23/2017. Certainly an intriguing report of an incredibly difficult identification. This record was supported by a description, photographs, and an audio recording. This report received support from a couple members who felt that the reddish tones of the bird coupled with the final phrase of the song being up-slurred was sufficient for acceptance. However, most members were not convinced that the photos and description of the physical appearance ruled out Gray-cheeked, although some members commented that separation of Gray-cheeked and Bicknell's Thrushes by physical appearance alone in the field may be impossible. The audio recording and description was the more critical part of this record. The songs of Gray-cheeked and Bicknell's Thrushes are distinct, with the final part of the song being typically down-slurred in Gray-cheeked and up-slurred in Bicknell's. The Bicknell's overall has a higher-pitched song than Gray-cheeked. Again, a couple members felt that they indeed could hear the final part of the song and that it corresponded to a typical Bicknell's. The other members, however, felt that the audio was not clear enough to be certain they were hearing the correct song, let alone the correct parts of the song. In addition, Gray-cheeked Thrushes can give isolated songs that contain an up-slurred final note similar to a Bicknell's. Therefore, for Bicknell's Thrush records in Massachusetts, it is critical to listen to a singing thrush over several songs and note whether the final parts of the songs are consistently up-slurred or down-slurred. Because the audio recording and description only pertained to a single song and despite the observers' excellent efforts at documenting this record, the members did not feel that Gray-cheeked had been ruled out with certainty.

Golden-winged Warbler (Vermivora chrysoptera)

2017-009: 1 at Borderland State Park, North Easton, Bristol, 4/23/2017 [Stephen Peabody*, Zach Moser*]. The description did not attempt to rule out intergrades with Blue-winged Warbler (Vermivora cyanoptera).

2017-011: 1 at Hopkins Memorial Forest, Williamstown, Berkshire, 5/28/2017 to 5/30/2017 [Ken Schopp* (ph)]. Photos revealed this bird had two whitish wing bars, which is a trait of Blue-winged Warbler.

Black-backed Oriole (Icterus abeillei)

2017-014: 1 at Putnam Hill Rd., Sutton, Worcester, 6/7/2017 to 6/8/2017 [Margaret Bowden* (ph)]. See the first part of this report for more details.
