| 1961 | Summer | | | Brother Theodore saw one adult sitting in the sand on Minnesota Point on 30 August. He approached within 12 feet of the bird. Again on 2 September, other members of the Avifaunal Club visited the area. We saw three Jaegers fly over the recreation area. Shortly thereafter we saw them sitting on Lake Superior near the small lighthouse at the end of the point. They then arose to harass a gull. TERNS: |
| 1961 | Fall | | | Three were seen at Duluth by Avifaunal Club members on 2 Sep. Not seen 9 Sep. Close looks at the amount of white in the primaries made the identification fairly certain. |

| 1990 | Fall | | | 9/2 Duluth (I) PS. |
| 1991 | Fall | | | All reports: 9/5 St. Louis (one adult, one imm.) PS, 9/14 St. Louis (adult) KR, 9/5 - 10/28 St. Louis (fide KE). |
| 1992 | Fall | | | One report: 9/7 St. Louis MH. |
| 1993 | Spring | | | One report: 5/24–31 St. Louis KE. |
| 1993 | Fall | | | All reports: 9/8, 18, 25 St. Louis KE, BL. |
| 1994 | Fall | | | Numbers up from 1993; 9/10–10/15 St. Louis mob, peak 9/20 St. Louis (4) PS. |
| 1995 | Fall | | | All reports: 9/23 St. Louis (2 adult light-morphs) BL, 10/2 St. Louis (1) MH, 10/14 St. Louis (1) JHe. |
| 1996 | Spring | | | Only report: 5/26 St. Louis (adult light morph) DBe. |
| 1996 | Fall | | | Two Duluth reports 9/21 (adult) JWe, 9/28 (two adults) mob. |
| 1997 | Summer | | | Adult light-morph bird observed on 6/2 at Duluth in St. Louis Co. fide KE; this is only the third summer record (the first since 1983) for this species. |
| 1997 | Fall | | | All reports: 9/1, 9/7 (dark-morph), 9/16 Duluth, St. Louis Co. fide KE. Unidentified jaegers reported 10/5, 10/12 Duluth mob. |
| 1998 | Spring | | | Many reports of one or two adult light-morph jaegers, all from St. Louis and presumably referring to the same individuals: 5/16 (Park Point) FN, 5/23 (Park Point) DN, 5/24 (Brighton Beach) TN and (Park Point) PS, 5/29 (Park Point) AH, PS, 5/30 (jaeger, sp?) mob. Two jaegers were reported off Wisconsin Point during this same time by Wisconsin birders. |
| 1998 | Fall | | | All Duluth reports: 9/7–28 (at least two adult light-morphs plus one jaeger, sp?) mob, 10/16 (adult intermediate morph) FN et al., 10/20 (age?) fide KE. Minimum of three and more likely four or more individuals for the season. Most unusual was an unidentified jaeger harassing thousands of Bonaparte's Gulls on Lower Red Lake, Beltrami Co. in late August (The Loon 70:243). |
| 1999 | Fall | | | All reports: 9/19 St. Louis (two Parasitics plus one unidentified off Park Point in Duluth) mob, 10/17 Lake (adult light morph in Two Harbors) fide KE, 10/20–21 St. Louis (adult light morph in Duluth) SDM, †PS, †KE. The latter two reports probably refer to the same individual. Many observers reported an immature jaeger 11/14–22 Cook (Grand Marais) as a Parasitic, but no documentation was submitted. This would be record late for a Parasitic but prime time for a Pomarine. |
| 2000 | Spring | | | No reports. |
| 2000 | Fall | | | All were on L. Superior in St. Louis County as expected: 8/31, 9/3 (adult light morph) †KJB, KRE; 9/3–4 (dark juvenile off Brighton Beach) †KRE, PME, possibly relocated 9/9 (Park Point) †AXH, AMH; and 9/23 (adult light morph) mob. |
| 2001 | Fall | | | More reports than usual from St. Louis County, especially at the Superior Entry where three Parasitics arrived 9/7 (SP). Sorting ages and morphs resulted in seasonal total of five to eight Parasitics (four adults) at Duluth, plus unidentified jaegers (see below). No Parasitics identified after 9/30. |
| 2002 | Spring | | | No reports. |
| 2002 | Fall | | | Scarce. One or two light-morph adults reported at or near the Superior Entry, 9/21–28 St. Louis m.obs. |
| 2003 | Spring | | | Adult light morph flew over astonished hawk watchers at the Thompson Hill lookout and continued southwest 5/16 (ties earliest date) St. Louis (W.S.H.C.) ph. FJN, DAG, JP. |
| 2003 | Fall | | | Adult light morph (plus one unidentified) 9/28 St. Louis m.obs., dark morph (age?) 10/4–9 St. Louis RMD, MH. |
| 2004 | Fall | | | Documented at Park Point, Duluth 9/10 (juvenile dark morph and adult light morph) †MTA, 9/23 (fide MH), 9/26–27 (adult light morph) †MTA, †PHS et al. |
| 2005 | Spring | | | Exceptional spring report 5/21–23 St. Louis (adult light morph with tail streamers, plus two light morphs lacking elongated central rectrices) ph. †JWL, †PHS. Record-high spring count. |
| 2005 | Fall | | | Juvenile hit by car 9/7 Chisago (Lindstrom) ph. TV (The Loon 78:116–117). All other reports from St. Louis: 9/9 (two juveniles) MTA, 9/19 (adult light morph) JPM, CMB, 9/25 (adult light morph with tail streamers being chased by smaller jaeger) m.ob. |
| 2006 | Fall | | | One of the best jaeger migrations ever witnessed on western Lake Superior. Ten or more individuals were carefully identified between 9/9 (when two adult and one unaged light-morph Parasitic Jaegers were videotaped several miles off shore during a boat trip) MLH, DWK, ADS et al. and 10/3 (when this species was last seen); the other seven identified as Parasitics included three adult light morphs, two light subadults, one juvenile dark morph, and one juvenile intermediate morph. Also note that at least five additional jaegers not identified to species were present during this time. Flocks of 5 Parasitics were observed 9/23 JWH and 10/1 PHS. Good numbers were also seen off Wisconsin Point during this time; MLH and RJ compared notes and estimated that at least 10–12 jaegers hunted western Lake Superior in late September. |
