A late pair of Northern Pintail re- mained in Clay, MN 19 Dec (PBB), while others likely wintered in Hennepin and Dakota. North - ern Pintail was recorded through 19 MI coun- ties, with a peak of 96 in Saginaw 18 Dec (RD). Very late for n. MN was a Redhead in Doug - las 5 Jan (BE), while an impressive flock of 19,190 lingered on L. Huron off Iosco, MI 3 Jan (RE). A Harlequin Duck was in Lake, MN 13-27 Feb (CN, JWL, JPR, m.ob.), while WI birders found 4 in four counties 7 Dec–3 Feb. MI hosted a single Harlequin Duck in Manistee 23 Dec (LS, BA), up to 2 in Ottawa, and one in Jackson. Numbers of scoters and Long-tailed Duck in MI were down from recent winters. In MN, lingering scoters included a Surf Scoter in Cook 8 Jan (DRB, LB) and single White-winged Scoters in Cook 5 Jan (DMB, CN, m.ob.) and Lake 16-28 Feb (JWL, BA, TL, m.ob.). Drake Barrow's Goldeneyes were in Roscommon, MI 18 Dec–9 Jan (BK, m.ob.), Milwaukee, WI 31 Dec–1 Jan (CP), and St. Clair, MI 9-17 Feb (RK, m.ob.). MN had a Common Goldeneye x WATERFOWL THROUGH SHOREBIRDS After going undetected last winter, MN hosted Greater White-fronted Geese in three counties, with the last report in Martin 17 Dec (BB). MI birders reported the species in seven counties, with a peak of 18 in Monroe (PO). MN birders also reported late Snow Geese in three counties, a Ross's Goose in Olmsted 8 Dec (JP), and many Cackling Geese through Dec, the latest being 4 in Wabasha 2 Jan (KDS, SW). Snow, Ross's, and Cackling geese were more widespread in MI, with reports from 19, 7, and 12 counties, respectively; this included a peak of 18 Cack - ling Geese in Isabella 8 Dec (RD). MN checked in with up to 5 Mute Swans in Wabasha dur - ing Dec, but then no reports until late-Feb in Goodhue, Winona, and Yellow Medicine. The late freeze in MN allowed Tundra Swans to linger in impressive numbers, illustrated by 14,000 in Houston 4 Dec (RPR), with 3000 still pres - ent 20 Dec (SO) and additional flocks in Wa- basha 2 Jan (GH, KDS, SW) and Nicollet 10 Jan (DK). Tundra Swans were recorded in 25 MI counties with a more normal peak of 1448 in Monroe 26 Dec (AMB). A potential first state record Mottled Duck was discovered in Anoka, MN 15-16 Feb (p.a.) (KM, AXH, RMD, TL, PHS, m.ob.). Blue- winged Teal were found in three MI counties, while in MN a pair visited an aerated pond in Isanti 20 Dec (RZ). Remarkable for MN were 200 Northern Shoveler in Martin 17 Dec (BB), followed by small flocks that lingered into late-Dec in Hennepin and Washington, and one that overwintered in Scott. North - ern Shoveler was reported in 20 MI counties, including 2500 still present in Muskeg - Adam M. Byrne –––––––––––––––––––––––––––––––––––––– D ecember was the warmest in modern history. Mild temperatures led to late, and reduced, ice cover; Great Lakes ice cover maximum was only 34%, well down from the 92% in 2013-14 and 74% in 2014- 15. January and February were also warmer than average across the Region. Snowfall events were unimpressive, with most areas near or just above average for the season. Exceptions were Michigan's eastern Upper Peninsula and southeastern Lower Peninsula, which were much above and below average, respectively. Snowy Owls again moved into the Region early, but numbers seemed to dwindle as the season progressed. Not surprisingly, the mild conditions led to a number of late records. Re - cord late in Minnesota was Ovenbird, North- ern Parula, and Indigo Bunting. Michigan was home to a Swainson's Thrush, two White-eyed Vireos lingered into January, and a Yellow- breasted Chat almost celebrated Christmas in the Upper Peninsula. Wisconsin birders also reported a White-eyed Vireo, along with a record-late Nashville Warbler. Topping the list of rarities this season were multiple Ivory Gulls in Minnesota and Wis - consin. Other highlights were Minnesota's first Mottled Duck; Gray-crowned Rosy-Finches in both Minnesota and Wisconsin; Black-throat - ed Gray Warbler and Golden-crowned Spar- row in Michigan.
