This winter season in Iowa had above normal temperatures in January and February and below normal temperatures in December, with above normal precipitation during the first two months and slightly below normal precipitation during the last month of the season in Iowa. There were five rain/snow events during December, with multiple rain events and only one snow event of consequence in January. There were only two measurable snow events during February, with several rain events during the month. Highest numbers of waterfowl reports were from December and February with fewer found in January. Overall duck numbers were below average during the period with most of the reports and higher numbers showing up on and after 13 Feb. All three scoter species plus Long-tailed Duck made a showing during the period. Most gallinaceous bird numbers were still on the low side with only Wild Turkey showing average with only two reports each of Northern Bobwhite and Gray Partridge. American White Pelicans were found in good numbers at Red Rock and Saylorville Reservoirs and at the locks and dams along the Mississippi River throughout the period.

There were multiple late winter reports of Turkey Vulture this year beginning on 14 Feb. Bald Eagles were found in good numbers along the Mississippi River and at the Army Corps of Engineer impoundments but were also down from last year. Gull reports were widespread in all three months. For northern owl species, Snowy Owls were found in below average numbers this year and there were good numbers of Northern Saw-whet Owls at the usual locations. Long-eared Owls were more abundant in February and Short-eared Owls were more numerous in December and January. Merlin were widely reported but only a few Peregrine and Prairie falcons were noted. Numbers of Horned Larks, Lapland Longspurs, and Snow Buntings were more numerous in December and January with a few records from February, mostly in the northern and central parts of the state.

There were good numbers of wintering sparrows throughout the period. Blackbirds made a good showing throughout the period as well. Winter finch numbers this winter were up this year from last year with reports of both species of crossbills along with good numbers of Common Redpolls and a few reports of Pine Siskins. Eurasian Tree Sparrows continue to expand their range with several found in Buchanan and Appanoose counties in Iowa.

Exceeding records of the previous year, 2016 came to a close as the third warmest year on record in Missouri with only 1921 and 2012 being warmer. The season started off with an early December cold front, leaving bodies of water frozen and showing promise of a reliable winter. Temperatures in December averaged a degree below normal, and drought from fall continued with slightly less than 1 inch below normal precipitation across the state. December was the second month in 2016 that averaged below normal temperatures with a significant storm on Dec 16–17 that left icy roads, shut down airports, and closed highways including I-70 in both directions. Early January showed temperatures near or below zero in the northern part of the state. These soon gave way to mild conditions, with 70s being reported in areas of the state on 17 Jan. February continued the warming trend, with statewide average temperature of approximately 45 degrees, more than 11 degrees above normal. Feb 2017 earned the title of the highest average February state temperature on record. Drought conditions accumulated in North and Central sections of Missouri with less than 1/2 inch of precipitation. Mark Haas described this season as “the winter that wasn’t” with personal observations of Cape Girardeau setting seven winter high records and only one inch of snow, which melted by the end of the day.

The winter of 2016–2017 ultimately ranked in the top five warmest winters on record and ended on 28 Feb with a deadly tornado in Perry County and significant wind and hail in southern and central Missouri. For many this will be remembered as the winter of Red-breasted Nuthatches, with an irruption that spurred reports across the state, especially around population centers. The warm temperatures of mid to late winter coincided with observations of species absent from reports earlier in the winter such as Prairie Falcon, Gray Catbird, and Golden Eagle. A few unexpected species reported were Say’s Phoebe, a first-winter male Lesser Goldfinch and two overwintering American Bitterns. Both Cattle and Great egrets took advantage of the mild winter, increasing their presence in the state significantly over prior winter reports. Orange-crowned Warbler had an exceptional presence in the state this winter, especially considering observations in this season required documentation in previous years. Almost absent from the state were Northern Shrikes, with the only reports coming from Columbia. Of note during this period, the U.S. Fish and Wildlife Service officially changed the name of Squaw Creek NWR to Loess Bluffs NWF.

Highlights of the season in Iowa were Brant, Great Black-backed Gull, Slaty-backed Gull, California Gull, Say’s Phoebe, and Lark Bunting. Seasonal highlights in Missouri were American Bittern, Cattle Egret, Say’s Phoebe, Lesser Goldfinch, and Brewer’s Blackbird.
