Mute Swan(Cygnus olor)
YearSeasonNS
1974Spring On 5-9 B. Hojnacki observed 3 swan of this species with 18 Tundra Swan in Lake Superior near Ashland, Wis. Possibly the same birds were observed near Duluth on 5-26 & 27 with 1 Whistling Swan by R. Fox & JCG (First state record).
1974Summer Three still present on 6-2 in the St. Louis R. in Duluth with Whistling Swans (D. Olson); if wild, these would represent a first state record; Mute Swans occur in good numbers in the wild in Michigan and strays have occurred several times on the Wisconsin and Illinois side of L. Michigan; these same three swans apparently wandered during 1974 on L. Superior to Wisconsin and Ontario.
1974Winter The most inconsiderate birds of the year were three Mute Swans which showed up at Grand Marais, Cook Co. on 1-27-the day after the M.O.U. winter trip; they remained here until mid-February; second state record.
1975Spring 2 reports: 3-8 Cook (Grand Marais) MMC; 3-14 & 3-16 Cook (Grand Marais) PVK & ETS.
1980Spring Many reports from St. Louis and Lake counties 3-8 (2), 3-16 (7), 3-25 (2) sp?, 3-30 (5), 5-23 (1) sp?, 5-31 (1), several observers.
1981Spring Several reports from Duluth: 3-15 (7) fide KE, 4-18 JG and 5-11 KE; also 3-20 through 28 ltascat TL.
1982Fall 10/20 to 11/11 Duluth, JB, KE, many obs. On Lake Superior this species is presumed wild, probably wandering from a feral colony at Ashland, Wisconsin; elsewhere in Minnesota it would be presumed an escaped captive.
1983Spring 3/24 to 26 Duluth KE, others.
1984Spring 4/24 to 4/26 Duluth KE.
1986Spring 4/l-9 Duluth KE, m.ob.

1987Fall Reported 10/23 to 11/27 St. Louis KE.
1987Winter The five seen on the lower Mississippi River near Reno, Houston County on 12/10 (KL) may have been wild or they may have been escaped park birds.
1988Spring 4/6-June Duluth KE et al.
1988Summer Two adults nested in Duluth, St. Louis, producing one young; this represents the first state nesting record (KE).
1988Winter Three present at Lake Rebecca, Hennepin Co. between 12/24 and 1/21 m.ob.

1992Winter One overwintered at Cannon Lake, Rice County (2) OR, FKS. Also reported until 12/11 at Grey Cloud Island, Washington County (1 from fall season) TEB, and on the Owatonna (2) CBC. The possibility that these reports are escapes or releases cannot be ruled out.
1993Spring Reported 3/21–4/2 Dakota mob.

2000Winter No reports.
2001Spring More reports than usual, but mostly near urban areas where origin questionable. Presumably “wild” based on habitat and remote location, one adult furnished a first county record 5/25 Polk (wild rice paddies along county road 2 in Johnson Twp.) KRE et al.

2007Summer1 One record: 6/22–26 Swift KRE, RPR, BJU. Undocumented reports from vague locations in Anoka and Sherburne lacked information about behavior and habitat; Mute Swans seen in urban or park settings during the summer are probably captive or recently released birds.
2007Fall5 Probable wild bird seen 10/14–11/22 Scott (Minnesota Valley N.W.R., Louisville Swamp) †BAF. Birds of uncertain origin 8/13 Freeborn (Upper Twin L.) JWH, 9/14 Sherburne (Sherburne N.W.R.) PLJ, 11/23 Meeker (L. Ripley) DMF, Rice TFB.

2012Spring4 All reports: 3/8–4/17 Goodhue (2, probable releases at Prairie Island) GJM, 3/20 Anoka TMu, 4/2–6 Waseca (Clear Lake) ANy, DBz, DAB, DBM, 5/27 Sibley SC.
2012Summer14 Seen 6/2 Dakota (Farmington) GHo, 6/23 Grant (2, Pelican Lake) MiG, 7/6–7 McLeod CRM, PRH, m.ob., 7/7–25 Sibley (Gaylord W.T.P.) DWK, SBM, m.ob., 7/13 Goodhue (Prairie Island) GJM. Whether or not any of these records represent wild birds is unknown.
2012Fall14 Only north report 9/7 of a probable wild bird Mille Lacs (Mille Lacs Kathio S.P.) MbH. All south reports of probable wild birds 9/22 Wright PEB, RBW, MJB, 10/19 Sherburne (Lake Orrock) PLJ. Reports of uncertain origin 9/2 Washington (5) JFR.
2012Winter4 Reports of up to three from January and February Goodhue (Prairie Island, Lock and Dam 3) m.ob. that probably originated from Treasure Island Casino. Other reports of single birds of unknown origin include 12/15–16 Scott (Shakopee Mill Pond) m.ob., 2/2 Dakota (Miesville Ravine C.P.) KDS.
2013Spring15 All reports 3/8 Dakota (Miesville Ravine) CKS, 3/8–5/15 Goodhue (2, probable releases at Prairie Island) m.ob., 3/30–4/1 Winona ANy, m.ob. 4/24 Nicollet (near Little Lake) TrR, 5/5–12 Steele (Ellendale) JWH, DAB, m.ob., 5/22 Pine (probable release at Grand Casino) ToL.
2013Summer1 Observed 6/28–30 Sherburne (Sherburne N.W.R.) HHD, DBM, MJB, WPe, RAE.
2013Fall15 Only north report 11/10 of a probable wild bird Pine (Pine City W.T.P.) BWF, ph. DWK, m.ob. All south reports of probable wild birds: 10/13–20 Sibley (along S.R. 22) †JCC, m.ob., 10/17 Nicollet (4 mi N of Nicollet; probably same individual seen in Sibley County) ph. KRE. Birds of uncertain origin: 8/7–30 Isanti (2, Anderson C.P.) JSa, BMc, 11/15 Wabasha (2, Altura) ANy, KLi, 10/20–11/3 Steele (Kohlmeier Lake) HCT, m.ob.
2014Spring7All reports: 3/18 Nicollet (near Courtland) BTS, 3/30 Goodhue (2, Sturgeon Lake) PEJ, 3/31 Nicollet ph. MiO, 4/2 Nicollet RAE, 4/5 Wright (Pelican Lake) HCT, 4/13 Renville JWd, 5/6 Blue Earth (Mankato) CJS, ChH, 5/11 Freeborn (Geneve Lake) PEJ, 5/18 Wabasha JMs.
2014SummerNo reports.
2014Fall2 Two south reports of probable wild birds: 10/11–12 Scott (New Prague W.T.P.) JWH, ph. GHo, m.ob., 11/6–7 Sibley (Gaylord W.T.P.) PEB, m.ob.
2014Winter2 All reports: 12/20 Wabasha (2 adults, 1 immature, Pool 5) PEJ, 2/25–27 Dakota (2 adults, 1 immature, Prescott WI area) KDS, ph. BAF (who confirmed that all 3 were unbanded). It is possible and perhaps likely that the Wabasha and Dakota birds were the same. Prairie Island Casino (Goodhue) origin of at least some of this area's Mute Swans has been suspected in past years, but GJM (Prairie Island Indian Community conservation biologist) reported that one member of the last Casino pair died in June 2013 and its mate was last reported in fall 2013, and there have been no further Mute Swan reports from Prairie Island since. This all suggests that these birds are “wild.”
2015Spring3 All reports: 3/11 Goodhue (3, Sturgeon Lake) KDS, 3/16–4/7 Wright (1, near Pelican Lake and St. Michael) KRy, m.ob., 3/17 Kandiyohi (1, Big Kandiyohi Lake) JrD, ph. †JWd, m.ob.
2015Summer2 Observed 6/20–21 Becker (Bisson L., Hamden Slough N.W.R.) JCC, KRE, RZi, †HeH, m.ob., 7/3 Todd (no details) FGo. The provenance of these birds is unknown, though the location of the Hamden Slough bird suggests wild origin.
2015Fall3 Three south reports of probable wild birds: 11/27 Kandiyohi (1, Green Lake, with 6 Trumpeter Swans) ALu; 11/27–29+ Wabasha (5, Minneiska, 2 immatures and 3 adults) BAF, m.ob.; 11/29+ Winona (one of the Minnieska group wandered into Winona County) DWK.
2015Winter4 All reports: 12/2–20 Wabasha (2 adults, 3 immatures; Minneiska) PEJ, PGL, 2/22 Winona (south of Minneiska) KnM, 2/27 Goodhue (2, Lock and Dam 3) DVe, Yellow Medicine (Wood Lake) ph. GWe.

BCM.
2016Summer1 Observed 7/13 Stearns (Lake George) AUm. Whether this individual was of wild origin is unknown.
2016Fall3 Three south reports of probable wild birds: 9/30–11/29 Wabasha (max. 3, seen in several locations) PEJ, m.ob.; 10/18 Nicollet (1, north of Nicollet) WCM; 11/12 Houston (2, Brownsville Overlook) PKS.
