| 72:40 | 1987-04-24 | Heron L. | Jackson | (record #99–38, vote 2–5). This record had been previously voted on, accepted and published (The Loon 59:211–212), but it was reconsidered at the request of a MORC member and cation primarily relied on the observer's description of this gull's bill color and hood shape and color, but these features are not easy to discern accurately at the distances involved. More importantly, the distinctive and diagnostic under wing pattern of this species was apparently not seen, since the documentation only says “it appeared dark from below.” | Not Accepted | ||||

| 67:165 | 1995-05-05 | Thief River Falls | Pennington | While the description of the black-tipped yellow bill suggests that this immature gull was correctly identified, such a bill pattern also fits a second-year Black-legged Kittiwake. The observer also describes and sketches an underwing pattern that does not fit Common Black-headed or, for that matter, any other gull: black wing linings and outer primaries contrasting with white secondaries and inner primaries. The gull is also described as being "halfway between juvenile and first winter," a most unlikely plumage to be seen in May. | Not Accepted | ||||
| 70:44 | 1997-05-27 | Forest L. | Washington | (record #97–48, vote 0–7). The entire description of the two individuals only includes the following: “dark auricular spot, red bill with black tip, red legs, and white tail.” With no mention of size or wing pattern, it was unanimously agreed that a potential third state record should be much more completely documented. | Not Accepted | ||||

| 70:156 | 1998-05-16 | near jct. of I–90 & Minn. Hwy. 86 | Jackson | (record #98-52, vote 2–5). Although the identification of this flying gull may well have been correct, the majority felt the description was not thorough enough for a third state record. The identification was based entirely on the description of the underwing pattern: “dark underwing primaries and also the darker secondaries but not as dark as a Little Gull (except the primaries)”. However, no mention is made of the Black-headed Gull's contrasting white outer primary, the secondaries on the underwing of this species are not dark, and the underwing pattern as described could fit either a Laughing or Little Gull. Except for the head being described as not being black, nothing else about the plumage is mentioned, the bill color was apparently not seen, and the overall size of the gull is unclear since nothing else was present for comparison. | Not Accepted | ||||
| 71:156 | 1998-05-29 | Duluth | St. Louis | (record #98-59, vote 1–6). Although it was agreed that both birds involved in this record were probably correctly identified, the identification relied only on bill color and overall body size to eliminate the similar Bonaparte's Gull, and for a potential fourth state record it was felt a more complete description was necessary. Most importantly, neither bird was seen in flight, so that this species' most diagnostic feature — its under wing pattern — was not visible. Also, since the observer was looking somewhat into the sun at the time, with the gulls about 100 yards away, it was felt that the described bill colors might not have been seen clearly enough. | Not Accepted | ||||

| 11 | 75:41 | 2002-09-20 | 2002-10-17 | Spirit Lake | Jackson | (record #2002-85, vote 7–0). This adult bird represents the fifth consecutive year that one or two adult Blackheaded Gulls have been documented at this location. Note that the only accepted records of this species come from Jackson County; besides this Spirit Lake location, the other records come from Grover's Lake in 1998 and Heron Lake in 1986. | Accepted | ||
| 12 | 77:9 | 2004-09-27 | 2004-10-17 | Spirit Lake | Jackson | (record #2004-103, vote 7–0). One adult, discovered on the Iowa side of the border 26 September 2004, was documented on the Minnesota side the following day and also was photographed 11 October. | Accepted | ||

This adult was first found on the Iowa side of the border by Minnesota birders looking for Iowa's Brown Pelican! It was photographed on both sides of the border and was reported regularly on the Iowa side of the border through at least 11 November, but the last verified sighting in Minnesota was 17 October. | Accepted | ||

| 89:87 | 2016-08-08 | Black Rush Lake Waterfowl Production Area/ Lyon County Landfill | Lyon | (record #2016-034, initial vote 5–2, recirculated vote 4–3). Of the eleven or more birders who saw the bird (some very experienced with the species), only one observer was willing to state categorically that the bird was a Black-headed Gull. The photographs are of poor quality and are only marginally helpful. Many of the observations were brief and the bird was often not well-seen at the time. At best, this was a Black-headed Gull in unusually pale plumage; however, the identification is still uncertain. | Not Accepted | ||||
