A warmer-than-normal winter bled into spring across Iowa and Missouri, with both states averaging March temperatures around 5°F above historical averages. Both states also experienced their wettest March in over a decade. The warmth of winter and early spring ended abruptly in April, with each state experiencing below-normal temperatures. The chilly April saw unusual midmonth snow fall across southern Iowa and northern Missouri. The cool temperatures of April persisted into May, when Missouri saw its coldest weather in nearly two decades. Precipitation was about normal for Missouri in April, but below average in Iowa. In May, Missouri’s precipitation was above normal, while Iowa’s was about normal.
Although COVID-19 arrived and shut down many parts of life during the spring season, birders managed to get out and document several rarities across the region. Highlight species included Mottled Duck, Ruff, Mew Gull, Yellow-billed Loon, Burrowing Owl, Vermilion Flycatcher, Sage Thrasher, Mountain Bluebird, Bullock’s Oriole, and Western Tanager.

Waterfowl through Cranes
Black-bellied Whistling Ducks continued to surge into Missouri. This season’s reports came from seven counties, with 15 in St. Louis Co 22 May being the northernmost (Cheryl Rosenfeld) and 40 in Scott Co 25 Apr being the highest count (Gary Sinn fide Mark Haas). Both states hosted six drake Cinnamon Teal 29 Mar–26 Apr. The easternmost individuals came from Green Island 4–5 Apr (ph. Tony Moline, m. ob.) and Mingo NWR, Stoddard Co, MO 7–9 Apr (ph. Lisa McClendon, m. ob.). Missouri’s 10th Mottled Duck was at Clarence Cannon NWR, Pike Co 18 Apr–4 May (ph.*Jerry Hemmersmeyer, ph.*Pete Monacell, ph.*Bill Rowe, ph.*Peter Kondrashov, ph.*Joshua Uffman, m. ob.) and MO’s 11th was across the state at Loess Bluffs 29 Apr–19 May (ph.*Tom Nagel, David Easterla). In IA, 3100 Northern Pintails at Saylorville 6 Mar (John Williamson), 1650 Canvasbacks at Hawkeye 4 Mar (Brandon Caswell), and 260 Redheads in Butler Co 16 Mar (Mark Welford) were all region highs. Iowa Ring-necked Duck numbers increased dramatically this spring with highs of 2573 at Green Island 1 Apr (Kelly McKay) and about 1000 at Otter Creek Marsh, Tama Co 8 Mar (Ken Saunders). A single male Greater Scaup at Cedar River Access, Johnson Co, IA was the last 30–31 May (ph. Mark Brown). An incredible total of 12,000 Lesser Scaup were noted at Eagle Point Park, Clinton Co, IA 31 Mar (Kelly McKay).

At Stockton Lake, 200 set a record-high count for MO 17 Apr (Ricky Hostettler, ph. Christian Hawn, Conway Hawn). Southern MO had four counts of at least 1000 American Golden-Plovers, with a high of 2500 in Dunklin Co 2 Apr (Timothy Jones). Missouri had a banner year for Piping Plovers, with observations coming from nine locations, including a high of five in Dade Co 18 Apr (ph. Christian Hawn, Conway Hawn). Up to five Whimbrel were at Hawkeye 11–16 May (Jonah Alderson, Jamie Tigges, Steven Freed), while an unprecedented 58 established a MO record-high count at Riverlands 24 May (ph. Dave Haenni, m. ob.). Ten Hudsonian Godwits at Loess Bluffs 9 Apr were MO’s first of the year (Doug Willis), while 10 in Woodbury Co the next day were IA’s. Loess Bluffs held the highest Hudsonian Godwit counts with 100–422 present 12–19 Apr (Mary Nemecek, m. ob.). Twenty-two Marbled Godwits there 22 Apr tied MO’s record high (ph. Mark Robbins). Twenty-seven Ruddy Turnstones at Hawkeye 14 May was an impressive total for the region (James Forde). A trio of Red Knots in Lincoln Co 14–15 May were only the second MO spring record since 2004 (ph.

Ruffs put on a good show in the region, with a breeding plumage male 11–16 Apr at Hawkeye tying IA’s second-earliest record (ph. *Dean Hester, ph. *Brandon Caswell, *Chris Edwards, *Jim Kettelkamp, m. ob.). In MO, singles were present in New Madrid Co 8–9 Apr (ph. Tim Kavan), St. Charles Co 18–19 Apr (ph. Joshua Uffman, m. ob.), and at Loess Bluffs 5–16 May (ph. Tom Nagel, David Easterla, m. ob.). Twenty-eight Sanderlings (James Forde) and 170 Dunlins (Craig Kruse, James McCoy), both 16 May, and 800 Pectoral Sandpipers 21 Apr (Steven Freed) all came from Hawkeye and were the region’s peak counts.
The first three White-rumped Sandpipers in the region established first- and second-earliest arrival dates for MO: Cole Co 17 Apr (Chris Barrigar, ph. *Paul McKenzie, ph. *Pete Monacell) and Eagle Bluffs Conservation Area, Boone Co 17–18 Apr (*Kathleen Anderson, ph. *Pete Monacell, m. ob.); then one at Schell-Osage Conservation Area, Vernon Co 18 Apr (ph. *Christian Hawn, Conway Hawn). Above-average Western Sandpiper reports were noted this spring, with one to two at five locations 14 Apr–12 May. Missouri’s first three Solitary Sandpipers set first- and second-earliest arrival records: 20 Mar in St. Louis Co (*Joshua Uffman) and then singles the next day in Christian Co (ph. Debbie Martin, Steve Martin) and St. Charles Co (ph. Jessie Goodwin, Tommy Goodwin). Hawkeye was a stopping-over point for approximately 3000 Lesser Yellowlegs 30 Apr (Jesse Ellis), while Eagle Bluffs Conservation Area, Boone Co, MO saw more than 5000 Lesser Yellowlegs after a front passed 28 Apr (Paul McKenzie).

Christian Hawn, Conway Hawn); and 79 at Riverlands 27 Apr, setting a new high count for eastern MO (ph. Cathy Spahn, David Haenni, m. ob.). Single Red-necked Phalarope reports came from three IA and two MO sites starting 2 May and ending with two in Johnson Co, IA 30 May (ph. Mark Brown).
Gulls through Pelicans
A Bonaparte’s Gull in Louisa Co 1 Mar was IA’s third-earliest spring arrival (ph. James McCoy, Jason McCurdy). Missouri hosted the only Laughing Gulls, all singles: St. Charles Co 11 Mar (ph. David Haenni); Clarence Cannon NWR, Pike Co 24 Apr (ph. Doug Hommert); and Greene Co 15 May (Kendell Loyd). A Mew Gull at Smithville Lake 11 Mar was MO’s second (ph. *Doug Willis, ph. Lisa Owens, ph.

An Anhinga in St. Louis Co 10–11 May was only the second spring record away from the MO bootheel (ph. *Yvonne Homeyer, ph. * Lisa Saffell, ph. *David Becher, m. ob). Four MO reports and one IA report of single Neotropic Cormorants all came from the western half of the region. In MO, an immature at Smithville Lake established the earliest spring record 11–18 Mar (ph. *Doug Willis, m. ob.) and the next at Schell-Osage Conservation Area, St. Clair Co 15–17 Mar established the second-earliest (Tony Elliott, m. ob.). A flight of 3465 Double-crested Cormorants at Smithville Lake 14 Mar set a record-high count for MO (Pete Monacell, Paul McKenzie).
Herons through Vireos
A Great Egret at Cone Marsh, Louisa Co tied IA’s record-earliest date 7 Mar (ph. Dawn Gunderson). The region’s only Tricolored Heron was at Loess Bluffs 22–30 Apr (Doug Willis, Mark Robbins, m. ob.). In St. Louis City, MO a rookery was found to hold 18 Snowy Egrets and 95 Black-crowned Night-Herons (Bill Rowe, m. ob.). Single Glossy Ibises were noted at six IA and three MO sites 14 Apr-24 May. White-faced Ibises put on quite a show, with a high of 42 at Trumbull Lake, Clay Co, IA 19 Apr (Lee Schoenewe) and an all-time-record high for MO of 204 at Loess Bluffs 22 Apr (Doug Willis). Further east in the region, and all in MO 17 Apr, 50 White-faced were in Cole Co (ph. Paul McKenzie, m. ob.) and counts of separate Plegadis flocks numbering 67 (ph. Jessie Goodwin, Tommy Goodwin) and 35 were made in St. Charles Co (Bill Rowe, Cornelius Alwood).
Missouri’s northwesternmost Black Vulture ever came from Loess Bluffs 13 May (David Easterla). In IA, Red-shouldered Hawks in Cerro Gordo and Greene counties were outside their expected range, 85 Broad-winged Hawks in Johnson Co was the region’s high 22 Apr (Jaden Bowen), and a Rough-legged Hawk 7 May in Clay Co was very tardy (Lee Schoenewe, Joe Jungers).

A Northern Saw-whet Owl in Mitchell, IA was late 12 May (ph. Tyler Reams fide Paul Skrade). A Merlin pair could be seen incubating eggs in Black Hawk Co, IA in the second half of May (Tom Schilke). A Prairie Falcon at Shawnee Trail CA, Barton Co, MO 7 Mar was the region’s only report (Tony Elliott).
In IA, 12 Alder Flycatchers in Polk Co 25 May (Karen Viste-Sparkman, Stuart Sparkman) and 30 Least Flycatchers in Story Co 17 May (Stuart Sparkman) were the region’s highest counts. An Eastern Phoebe 2 Mar in Des Moines Co tied IA’s earliest arrival date (Bobby Wilcox). A Say’s Phoebe was in Dade Co, MO 17–28 Mar (*Steve Martin, ph. Debbie Martin, m. ob.). Missouri’s 13th Vermilion Flycatcher was in Lawrence Co 23–24 Apr (Lyndon Hostetler, Steve Martin, ph.*Debbie Martin, m. ob.). Counts of four Loggerhead Shrikes came from three widely separated MO sites, while the northernmost reports came from Boone, Greene, and Story Cos in IA. The southernmost Northern Shrike reports came from Boone and St. Louis Cos, MO 10–23 Mar, while the last was at Saylorville 2 Apr (RJ Thompson). Iowa’s second-earliest spring White-eyed Vireo was in Polk Co 10 Apr (Diane Dentlinger, Dennis Thompson, m. ob.).

Missouri checked in with a new record-high spring count of 43 in Barton Co 26 Apr (Doug Willis), and IA had a high count of 27 at Neal Smith NWR, Jasper Co 9 May (Carl Schimmel). Fifty-eight Marsh Wrens were at Legacy WA, Hardin Co, IA 12 May (Connor Langan). After two springs with no Bewick’s Wren reports in IA, one returned to the Argyle Junkyard, Lee Co. starting 18 Apr (James McCoy). A Blue-gray Gnatcatcher in Black Hawk Co 4 Apr tied IA’s earliest spring record (Alan Orr, Karen Orr).
A Mountain Bluebird continuing from the winter season at Deere Dike, Dubuque Co, IA remained until 27 Mar (Tony Moline). In Clay Co, MO nocturnal flight call counts resulted in 14 Veeries 15 May, 92 Gray-cheeked Thrushes 13 May, and a whopping 255 Swainson’s Thrushes 13 May (Marky Mutchler). In IA, the same protocol resulted in a tally of 82 Swainson’s Thrushes 14 May in Linn Co (Jesse Ellis).

Two American Pipits in Johnson Co 23 May established a second-latest IA record (James McCoy), while one in Winneshiek Co, IA was still notably late 18 May (Paul Skrade). Red Crossbills were at four IA sites and one MO site, including highs of 10 in Linn Co, IA 1 Mar (Paul Morf) and nine in Johnson Co, IA 19 May (Jody Troyer, Chris Troyer). White-winged Crossbill pairs were in O’Brien Co, IA 6 Mar (Lee Schoenewe, Joe Jungers) and Buchanan Co, MO 7 Mar (Robert Irwin, m. ob.).
Longspurs through Blackbirds
Approximately 400 Lapland Longspurs in Dubuque Co, IA 14 Mar was the region’s highest count (Tony Moline), while one at Legacy WA, Hardin Co 12 May tied IA’s third-latest date (Connor Langan). Single Snow Buntings made it as far south as Worth (John Bissell) and Bremer (Mark Welford) Cos in IA, both 14 Mar. A pair of Lark Sparrows in Jackson Co 1 Apr represent the second-earliest spring record for IA (Kelly McKay). A Clay-colored Sparrow from the winter season remained at Riverlands through 5 Apr (ph. *Bill Rowe, Jim Malone, Tommy Goodwin, m. ob.), while three there 5 May was an impressive high for the eastern side of the region (Tommy Goodwin). Up to two Fox Sparrows at Springfield Conservation Nature Center, Greene Co set the latest MO spring record 12–15 May (ph. *Jordanya Raos, Dan Liles, Eric McMillan). Both MO and IA still had lingering White-crowned Sparrows present 30 May, with the one in St. Louis Co tying the second-latest MO record (ph. Joshua Uffman). Single Harris’s Sparrows in Lincoln Co, MO 15 Mar (Jerry Hemmersmeyer) and St. Louis Co, MO 30 Apr–1 May (ph. Joshua Uffman) were notable in the eastern half of the region.
