| 57:119 | 1984-05-27 | Carlos Avery W.M.A. | Anoka | (vote 3-4) . This record, which was originally accepted on a 6-1 vote and published (The Loon 56:194) , was reconsidered and found unacceptable . The identification was based on its all red bill, shorter legs , and gray underparts/white cheek line. However, Common Terns can also appear to look the same way: in breeding season their bills often turn almost entirely red with little or no black tip; a tern when not standing fully erect, when standing in a slight depression , or when its belly feathers are fluffed up can appear to have shorter legs; and, depending on light conditions or angle of observation, Commons often appear to have a white cheek line/grayer underparts appearance. Such marks are only valid when noted with caution (there is no indication the observer was aware of these caveats, however), and when viewing conditions are favorable (not the case here since the distance was 300 feet, and the bird was to the northwest with the sun to the west). | Not Accepted | ||||

| 8 | 70:44 | 1997-05-29 | Duluth | St. Louis | (record #97–50, vote 7–0, The Loon 70:59–61). | Accepted | |||

| 72:40 | 1999-05-11 | Duluth | St. Louis | (record #99–43, vote 1–6). Although the experienced observer's documentation describes this tern's darker gray underparts, “surprisingly short” legs, and folded wing tips falling short of the tail tips, the distance involved and the light conditions at the time were less than optimal to see clearly these subtle features. While it was agreed the identification may well have been correct, the bill color and shape, the translucent flight feathers, and the width and extent of the black edge on the underside of the primaries were not visible or described. Also, this tern's body is described as “slimmer” in direct comparison with Common Terns, but in flight an Arctic Tern should appear more “neckless” and “pot-bellied” — not slimmer — in comparison with Commons. | Not Accepted | ||||

| 12 | 74:161 | 2001-09-19 | 2001-09-21 | Duluth | St. Louis | (record #2002-04, vote 6–1, The Loon 74:120–121). This adult was seen on both the Minnesota and Wisconsin sides of the Superior Entry, the shipping channel separating Park Point from Wisconsin Point. The identification is primarily documented by excellent photos showing the diagnostic pattern on both the upper and under sides of the primaries. | Accepted | ||
| 13 | 74:161 | 2002-05-27 | Duluth | St. Louis | (record #2002-24, vote 6-1). This tern was seen well in flight in direct comparison with Common Terns by an experienced observer who took field notes at the time of the observation. These notes include the combination of its different shape, flight style, wing pattern of the upper and lower surfaces, grayer underparts, and contrasting whiter cheeks. | Accepted | |||
| 14 | 76:152 | 2004-05-15 | Breckenridge wastewater treatment ponds | Wilkin | (record #2004-044, vote 7–0). Fourteenth state record, but only the third to be photographed and the only Accepted record away from Duluth. | Accepted | |||
| avian information | 2004-05-15 | Wilkin | 5/15 Wilkin (first state record) (first county record) Single adults 5/15 Wilkin (Breckenridge W.T.P.) ph. †PHS, ph. JWL, SLL (The Loon 76:234–235), 5/23 St. Louis (Duluth) †MH. The former represents the only accepted record of this species away from Duluth. | ||||||
| 15 | 76:152 | 2004-05-23 | Park Point | St. Louis | (record #2004-066, vote 6–1). The uniform light gray upperwing of this “neck-less” adult tern was carefully studied over an extended period of time to ensure that it lacked Common Tern's dark wedge; however, whitish secondaries and translucent primaries were not noted, which precluded unanimous acceptance. Contemporaneous field notes and sketches showed a black cap extending to the base of its dark red bill, contrasting white cheeks, grayish under-parts, and a thin black trailing edge on the underside of its outer wing. | Accepted | |||
| 16 | 77:9 | 2004-09-25 | 2004-09-27 | Superior Entry | St. Louis | (record #2004-101, vote 7–0). Third fall record in five years at this location. | Accepted | ||
| 77:9 | 2004-10-09 | South Kawishiwi River | Lake | (record #2004-107, vote 0–7). This black-billed tern with an entirely white underbody and partial black cap must have been in juvenal or basic plumage, or a combination of the two, yet its upperwing was described as uniform gray and its underwing showed only a hint of gray on the trailing edge; an Arctic Tern in this plumage would show a black trailing edge on the underside of the outer wing, a carpal bar on the upperwing, and (if a juvenile) whitish secondaries. Three Accepted fall records of this species in Minnesota have involved adults in alternate plumage at the Superior Entry in midto late September. | Not Accepted | ||||

Though nearly a week apart, these two sight records may refer to the same adult. This species has now been found at the Superior Entry in four of the last six fall migrations — all within a narrow window between the 18th and 27th of September. | Accepted | ||
