| avian information | 1997-11-26 | 1997-12-13 | St. Louis | 11/26-12/13 St. Louis (fourth state record) (first county record) Second state record found 11/26 St. Louis (Duluth) KB. This individual in second-winter plumage could not be relocated until 12/13 when it returned to the Minnesota side of the Superior Entry; it was then seen only at the Superior landfill in Douglas County, Wisconsin through at least 12/22 (PS). | |||||
| 3 | 70:44 | 1997-12-01 | 1997-12-02 | Grand Marais | Cook | (record #97–86, vote 7–0). | Accepted | ||
| avian information | 1997-12-01 | Cook | 12/1 Cook (fifth state record) (first county record) Second and third state records noted 12/1 Cook (first-winter bird in Grand Marais) PS and 12/13 St. Louis (second-winter bird in Duluth) KB, PS. The latter individual was first seen on 11/26 and thus represents the second Minnesota record. | ||||||
| avian information | 1998-01-02 | Dakota | 1/2 Dakota (sixth state record) (third county record) Second and third state records noted 12/1 Cook (first-winter bird in Grand Marais) PS and 12/13 St. Louis (second-winter bird in Duluth) KB, PS. The latter individual was first seen on 11/26 and thus represents the second Minnesota record. | ||||||
| 73:35 | 1999-11-15 | 1999-12-04 | Grand Marais | Cook | (record #99-66, vote 0–7). The numerous photographs and written descriptions of this second-winter gull were sent for comment to three reviewers from other states with extensive experience with this species. One of them felt the identification was probably correct, but the other two had reservations about it, especially since the small bill size, the small and slight overall body size and structure, and some atypical pigmentation on the wing coverts and primaries seem inconsistent with this species. In addition, some of the observers documenting the record (including five MORC members) had reservations about the identification. While the gull may well have been a Glaucous-winged, the possibility of it being a hybrid or an atypically plumaged Herring Gull remains. | Not Accepted | |||
| 80:5 | 2007-01-07 | Reads Landing | Wabasha | (record #2007-052, vote 0–7). Documentation was submitted seven months later for a “uniformly colored, tawny-fawn” first-cycle bird that was “noticeably larger” than nearby Herring Gulls, and “similar in size” to an adjacent Glaucous Gull. Glaucous-winged Gull averages similar in size to a Herring Gull and is typically smaller than a Glaucous Gull (Howell and Dunn 2007). | Not Accepted | ||||
| 4 | 81:115 | 2009-05-01 | Superior Entry | St. Louis | (record #2009-010, vote 7–0). Fourth state record. First-cycle bird, photographed. | Accepted | |||
| avian information | 2009-05-01 | St. Louis | 5/1 St. Louis (seventh state record) (second county record) The fourth state record of this species was a first-cycle bird found 5/1 in St. Louis (Superior Entry) ph. †PHS. | ||||||
| 5 | 84:3 | 2011-12-22 | 2012-01-15 | Canal Park, Duluth | St. Louis | (record #2011-049, vote 7–0). There are numerous excellent photos, including those showing the spread wing. The detailed descriptions by experienced gull observers leave little doubt about the identification. Every feature for distinguishing Glaucouswinged Gull from other large white-headed gulls is shown and described. One might suspect possible hybridization (possibly even several generations back) due to the somewhat rounded head and bill shape. However, without something else anomalous about its plumage, size, or shape, it seems more plausible that the head and bill simply represent a small female Glaucous-winged Gull. Photographed. Fifth state record. | Accepted | ||
| avian information | 2011-12-22 | 2012-01-15 | St. Louis | 12/22-1/15 St. Louis (eighth state record) (third county record) Well-photographed and described adult 12/22–1/15 St. Louis (Duluth, mostly Canal Park) ph. †KJB, ph. †PHS, ph. ANy. This is the fifth record for Minnesota. (See The Loon 84:102.) | |||||
| 93:47 | 2020-11-22 | 2020-11-23 | Specialized Environmental Technologies Inc.; Empire Dump and 140th St. Marsh | Dakota | (record #2020-071, vote 2–5). Photographed. Opinions of independent gull experts were considered by MOURC. The Committee voted (5–2) to Accept the observation as an unknown hybrid gull. Among the many hybrid possibilities, both Western/ Glaucous-winged and Herring/Glaucouswinged were specifically considered but were unanimously (vote 0–7 for each specifically considered hybrid). | Not Accepted | |||
