On May 13, 2019, while conducting seabird and marine mammal surveys well offshore, Allison Black photographed a strange falcon that landed on her NOAA vessel. The strong moustachial stripe, striped breast, and the orange undertail coverts identified this bird as a Eurasian Hobby. During intensely high seas and rain, the small falcon circled the ship and landed several times over a period of 45 minutes.

On June 15, 2019, Lisa Schibley visited Mass Audubon's Daniel Webster Wildlife Sanctuary to follow up on a Scissor-tailed Flycatcher report. Upon her arrival, a different flycatcher with a bright yellow belly whizzed past her. Although Western Kingbird is the default yellow-bellied kingbird in Massachusetts, Lisa ruled out this species due to this kingbird's large bill and lack of white on the outer vane of the outer rectrix. She alerted the community to the presence of a Tropical or Couch's Kingbird, which according to some authorities are impossible to distinguish based on plumage alone. Audio recording subsequently confirmed it as a Tropical Kingbird, a second state record. After Lisa's report, another observer, Nancy Blake, realized that she had photographed the bird the previous day. It remained until July 4. The source population for vagrant Tropical Kingbirds is not well known; some may represent austral migrants.

During a NOAA cruise for mammal and seabird surveys in July and August 2018, Skye Haas photographed several noteworthy rarities for Massachusetts deep waters, including a third state record of Masked Booby and Trindade Petrel, two Red-billed Tropicbirds, and two Brown Boobies. These sightings occurred during a month of daily surveys beyond the continental shelf. Another survey in 2019 yielded similar results (those records have not yet been reviewed by the committee). The results pose the question: Are these pelagic species true rarities in Massachusetts, or are they part of the regular cast of the fauna in a relatively inaccessible area? With ocean temperatures warming overall and showing occasional "heat waves" that affect the distribution of better-known species, the question arises if the distribution of these species is changing as well. The answer is yes for Brown Booby, but much less clear for the other species.

David Sibley found a California Gull bathing with the local gull crowd at Turners Falls in Montague. The gull departed with some Herring Gulls less than an hour later, and extensive searching later in the day yielded no additional sightings. This was a fourth state record, the first since 2005, and the first for a landlocked county in Massachusetts.

During an International Shorebird Survey at the Powder Hole on Monomoy National Wildlife Refuge (NWR) on August 19, 2018, Sean Williams, Marshall Iliff, Sue Finnegan, and John Pratt sighted a worn, male "ringed" plover, apparently in first-summer plumage. The bird appeared larger, paler, and with a more prominent eyebrow than nearby Semipalmated Plovers. Lack of webbing between the toes and a vocalization confirmed the identification as a Common Ringed Plover, a fifth state record. Sean and Marshall saw what was almost certainly the same individual on September 2 on a beach roost at high tide, five miles north of the original location. (The MARC formally considered it the same bird, based partly on plumage details.)

A Sage Thrasher dashed by Logan Kahle at Low Beach on Nantucket on November 25, 2018. Its stealthy habits evaded many observers, although some fortunate souls caught up with the bird the next day. This was a fourth state record and the first for Nantucket County.

The committee accepted a 1990 report of a Ross's Gull by the legendary, late Richard Forster, who sighted the bird on Niles Pond in Gloucester on February 1. Although no photographs were obtained, this experienced observer published an extensive account of his encounter in Bird Observer June 1990, volume 18, number 3, covering all plumage aspects and addressing potential identification pitfalls. Old, credible reports such as these are vital, exemplary pieces of ornithological history in Massachusetts. This was a second state record.

Favorable southwesterly winds and a long-term increase at the northern edge of the range combined for an exceptional year for Mississippi Kites, especially away from Cape Cod. Nine records were accepted in 2019, which was more than any other previous year.

The 2018–19 roster of MARC voting members included Nick Block, Marshall Iliff, Jessica Johnson, Wayne Petersen, David Sibley, Ryan Schain, Tim Spahr (chair), Jim Sweeney, and Larry Therrien. Sean Williams served as a nonvoting secretary.

Species taxonomy and nomenclature follow the seventh edition of the American Ornithological Society (AOS, formerly 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, Chesser et al. 2018, Chesser et al. 2019).

The list of species reviewed by the MARC (the Review List) is available at maavianrecords.com. Please check the Review List to send evidence of records that are not listed in our Searchable Database—even in this Information Age we often do not receive sufficient information for many records. The committee strongly encourages written submissions even when photographs are available.

The statistics in brackets for each species or taxon show the number of records accepted in this report, followed by the total number of accepted records for that species. Species that lack statistics are species for which we have a relatively poor handle on the number of actual records, or it is a species reviewed due to its unseasonality. Below, we present data for all records covered, formatted as such: Record identification number, count of individuals, location, range of observation dates, original observers, and observers submitting documentation. We credit the discoverer with an asterisk (*). We indicate whether the evidence provided was photographic (ph), video (v), audio (au), or a written submission (†).

Ross's Goose records continue to increase. The Children's Island bird represents a record early date and the first September record for the state. Elimination of potential hybrids has been a contentious issue for the MARC, so observers are advised to describe the shape of the head and bill in detail and obtain photos from as close a range as possible.

Pink-footed Goose (Anser brachyrhynchus) [1, 18]

2018-069: 1 at Argilla-Northgate-Essex Fields, Ipswich, Essex, 11/8/2018 to 11/15/2018 [Phil Brown* (ph)].

Rufous Hummingbird (Selasphorus rufus) [1, 37]

2018-051: 1 at Lafayette Drive, Peru, Berkshire, 7/26/2018 [Ed Neumuth* (ph)].

Rufous Hummingbird records seem to be on the decline in recent years; July records often pertain to adult males, as with this bird.

Purple Gallinule (Porphyrio martinica) [1, 11]

2019-026: 1 at Cohasset Golf Course, Cohasset, Norfolk, January 2019 [Sally Avery* (ph)].

Common Ringed Plover (Charadrius hiaticula) [1, 5]

2018-037: 1 at Monomoy NWR, Chatham, Barnstable, 8/19/2018 to 9/2/2018 [Sue Finnegan*, Marshall Iliff* (ph), John Pratt*, Sean Williams*† (ph, au, vi)].

With only one record until the state's second in 2010, the four records since 2013 (one still pending MARC review) reflect a notable increase, probably due more to increased observer awareness of this subtle identification than a change in status.

Curlew Sandpiper (Calidris ferruginea) [1, 5]

Little Stint (Calidris minuta) [1, 8]

2018-036: 1 at Monomoy NWR, Chatham, Barnstable, 7/31/2018 [Maili Waters*† (ph), Sean Williams*† (ph)].

South Polar Skua (Stercorarius maccormicki)

2018-058: 2 at 41.0447,-69.5588, Nantucket, 08/25/2018 [Brookline Bird Club (BBC) Extreme Pelagic].

Ross's Gull (Rhodostethia rosea) [1, 2]

1990-07: 1 at Niles Pond, Gloucester, Essex, 2/1/1990 [Richard Forster*].

Mew Gull (Larus canus) [3, 22]

2018-074: 2 at King's Beach, Lynn, Essex, 11/24/2018 to 2/6/2019 [Suzanne Sullivan* (ph)].

2018-075: 1 at Loblolly Cove, Gloucester, Essex, 11/27/2018 [Ryan Doherty* (ph)].

2019-040: 1 at Race Point, Provincetown, Barnstable, 4/7/19 to 4/17/19 [Peter Flood* (ph)].

Mew Gull records have been surging in recent years, and have involved at least three taxa: Larus canus canus from western Europe, Larus canus brachyrhynchus from the Pacific coast of North America, and birds matching Larus canus kamtschatschensis from east Asia. The MARC has yet to formally assess the subspecies of these records, but plans to review these records at that level as well.

California Gull (Larus californicus) [1, 6]

2019-003: 1 at Turners Falls Power Canal, Montague, Franklin, 03/17/2019 [David Sibley* (ph)].

Gull-billed Tern (Gelochelidon nilotica) [2, 12]

2014-073: 1 at North of Dogbody Canyon, Nantucket, 8/24/2014 [BBC Extreme Pelagic].

2015-074: 1 at Hydrographer/Welker Canyon, Nantucket, 8/22/2015 [BBC Extreme Pelagic].

2018-034: 1 at 40.429,-66.637, Nantucket, 7/24/2018 [Skye Haas* (ph)].

2018-035: 2 at 40.54283,-66.526, Nantucket, 8/14/2018 [Skye Haas* (ph)].

Pacific Loon (Gavia pacifica)

2018-060: 1 at Race Point, Provincetown, Barnstable, 9/30/2018 to 10/20/2018 [Kate Sutherland*, Peter Flood* (ph)].

2018-065: 1 at Little Harbor Beach, Wareham, Plymouth, 10/2/2018 to 10/3/2018 [Lisa Schibley* (ph)].

2018-072: 2 at Race Point, Provincetown, Barnstable, 11/21/2018 to 02/03/2019 [Peter Flood* (ph), Kate Sutherland* (ph)].

2018-077: 1 at Andrews Point, Rockport, Essex, 12/16/2018 [Nathan Dubrow* (ph)].

2019-007: 1 at Salt Pond, Falmouth, Barnstable, 01/30/2019 to 02/03/2019 [Evan Dalton* (ph)].

Trindade Petrel (Pterodroma arminjoniana) [1, 3]

2018-030: 1 at Bear Mount Canyon, Nantucket, 8/9/2018 [Skye Haas* (ph)].

Likely more regular than the three records suggest, all Trindade Petrels have been found by seabird researchers from waters south of the continental shelf—beyond the reach of recent organized pelagic trips. Whether the three recent records are solely from increased recent coverage of deep waters or because of recent increases in ocean temperatures is unknown.

Masked Booby (Sula dactylatra) [1, 3]

2018-032: 1 at Munson Canyon, Nantucket, 8/13/2018 [Skye Haas* (ph)].

Brown Booby (Sula leucogaster) [8, 16]

2018-053: 1 at 39.852,-67.908, Nantucket, 7/30/2018 [Skye Haas* (ph)].

2018-054: 1 at Menemsha, Chilmark, Martha's Vineyard, Dukes, 8/6/2018 to 8/9/2018 [Laurie Lee* (ph)].

2018-055: 1 at 39.852,-67.908, Nantucket, 8/14/2018 [Skye Haas* (ph)].

2018-056: 1 at Onota Lake, Pittsfield, Berkshire, 8/17/2018 to 8/20/2018 [Rene Wendell* (ph)].

2018-059: 1 at Andrews Point, Rockport, Essex, 9/2/2018 [Rick Heil* (ph)].

2019-030: 1 at pelagic waters- 40.00651167, -70.8296933, Nantucket, 7/9/2019 [Allison Black* (ph)].

2019-031: 1 at pelagic waters- 39.58307167, -70.56025167, Nantucket, 7/10/2019 [Allison Black* (ph)].

2019-032: 1 at pelagic waters- 39.80960833, -70.482395, Nantucket, 7/10/2019 [Allison Black* (ph)].

Brown Booby has shown perhaps the most astonishing change in status across all species in Massachusetts in the past decade and the MARC still requests formal submissions to help document this remarkable change. Allison Black's three birds across two days matches the state total up until 2005. Of particular note is the state's second inland record, which was also a Berkshire first.

Records Not Accepted

Ross's Goose

2018-048: 1 at Bartholomew's Cobble, Sheffield, Berkshire, 10/13/2018.

Some members found the distant, in flight photos to be acceptable documentation for a pure Ross's goose, but several members felt a Snow x Ross's Goose hybrid could not be eliminated and the record was thus not acceptable.

Western Grebe

2019-027: 1 at Quabbin Reservoir, Shutesbury, Franklin, 6/19/2019.

The brief description did not eliminate other possibilities.

White-winged Dove

2019-014: 1 at The Club at New Seabury, Mashpee, Barnstable, 4/22/2019.

Some members found the combination of distant photos and description acceptable, but some were concerned about the brief description and failure to fully eliminate Eurasian Collared-Dove.

Bermuda Petrel

2018-031: 1 at Hydrographer Canyon, Nantucket, 8/18/2018.

Members thought the brief description of a highly significant rarity was not sufficient for acceptance.

Barolo Shearwater

2018-033: 1 at Munson Canyon, Nantucket, Nantucket, 8/13/2018.

Members thought the brief description of a highly significant rarity was not sufficient for acceptance.

Little Egret

2019-019: 1 at Pikul's Farm, Rowley, Essex, 5/4/2019.

The distant photos and brief observation in the field, not supported by detailed field notes, was not considered sufficient, especially with hybrid egrets a potential concern.

White-faced Ibis

2019-023: 1 at Scotland Road, Newbury, Essex, 4/20/2019.

2019-025: 1 at Chebacco Woods, Hamilton, Essex, 5/17/2019

Some members thought the photos of the Chebacco Woods bird were sufficient for acceptance, while others were concerned about the poor quality of the images. Furthermore, members were troubled that this record lacked any written description. Photos from the Scotland Road record matched Glossy Ibis not White-faced.

Swallow-tailed Kite

2005-062: 1 at east of Bourne Bridge, Bourne, Barnstable, 4/16/2005.

Hoary Redpoll

2018-046: 1 at Pine Hill Road Grasslands, Bolton, Worcester, 12/6/2018.

Putative Hoary Redpoll records are difficult to assess, especially when only seen from below. Committee members were split on the identification of the Pine Hill Road's bird, but all agreed that photos showing the bird in profile or showing the upperparts would have been helpful.

Boat-tailed Grackle

2018-040: 1 at Western Avenue, Essex, Essex, 4/29/2018.

The audio recording likely represented a mimid (e.g., Gray Catbird), possible with Boat-tailed Grackle-like phrases learned from the wintering grounds.

Golden-winged Warbler

2019-017: 1 at Jason Street marsh, Pittsfield, Berkshire, 4/24/2019.

Elimination of hybrids remains important in records of this species. The brief description here was not unanimously thought to be conclusive.
