V O L U M E 6 9 ( 2 0 1 6 ) • N U M B E R S 3 / 4 405 I O WA & M I S S O U R I pecially heavy rain fell on 24 June across mid- Iowa, leading to severe flooding in the Raccoon River watershed with flood crests rivaling those of 1993 and 2008. In July, the heaviest rain fell in the second half of the month, with the southern half of Iowa receiving the most rain. These conditions likely had a detrimental effect especially on grassland ground nesters. Marsh conditions were very good in some areas, but little shorebird habitat was available. Regional highlights were the Region's first report of nesting by Spotted Towhee, nesting Short-eared Owls in Missouri, and a Swain - son's Warbler far north of its usual range. The nesting ranges of Bald Eagles, Sandhill Cranes, Scissor-tailed Flycatchers, Western Kingbirds, and Blue Grosbeaks continued to expand with - in the Region, and Black-bellied Whistling- Ducks were found in both states. Abbreviations: Clinton spoil islands (spoil is - lands in Mississippi River, Clinton, IA); Cone Marsh (Cone Marsh W.A., Louisa, IA); Eagle Bluffs (Eagle Bluffs C.A., St. Louis, MO); Foun - tain Grove (Fountain Grove C.A., Linn and Livingston, MO); Hawkeye (Hawkeye W.A., Johnson, IA); Multiple Species Inventory and Monitoring (MSIM); Riverlands (Riverlands Migratory Bird Sanctuary, St. Charles, MO): Saylorville (Saylorville Reservoir, Polk, IA); Shimek (Shimek S.F., Lee, IA); Squaw Creek (Squaw Creek N.W.R., Holt , MO); Trumbull (Trumbull Lake, Clay, IA). DUCKS THROUGH HAWKS Black-bellied Whistling-Ducks continued their push into the Region, with two reports from each state: 2 in Scott 15-21 Jun (BCa, †MB, m.ob.) and 2 at Sweet Marsh, Bremer 8 Jul (ph. Logan McEwan, fide SJD) in Iowa, and 2 in Jasper 17 Jun (ph. Dennis Divine) and 2 at Fountain Grove 14 Jul (fide SK) in Missouri. Black-bellied Whistling-Ducks have been seen in the Region in seven of the past 10 summers. Two Fulvous Whistling-Ducks made a brief appearance in Pemiscot , MO 16 Jul (ph. TiJ), the first summer record for the Region since 2012 and the first for Missouri since 2010. Summering Greater White-fronted Geese are becoming more common in both states, with singles at Fountain Grove and in Johnson in Missouri and Hancock, Johnson, and Louisa in Iowa (m.ob.). Lingering waterfowl included an American Wigeon at Cone Marsh 14 Jun (JFo), 2 Gadwalls at Squaw Creek 30 Jun (MR), Northern Shovelers at seven and Northern Pintails at four locations in Missouri (m.ob.), a Green-winged Teal at Squaw Creek 27 Jun (ph. Ra Del Hinckley), a Canvasback at Eagle Bluffs 12-13 Jun (†Karen Wosilait), and one or 2 at Union Slough N.W.R., Kossuth, IA 16 Jun and as several scattered reports came to eBird dur- ing the second half of May, with one still far s. in Dunklin 31 May (TJ). Lastly, a Eurasian Tree Sparrow in Cass, MO was far w. of the species expected St. Louis area range 1-5 Mar (ph., †Ginny Culver).

Dinsmore W eather conditions were similar in both states—normal temperatures but with Iowa having a somewhat cooler July than usual. Both states experienced a wetter-than-normal summer. In June, parts of northeastern, east-central, and west-central Missouri received more than 25 cm (10 in.) of rain, due in part to remnants of Tropical Storm Bill, leading to widespread flooding. Wet con - ditions continued into July, which was Mis- souri's wettest July since 1993, with 35-38 cm (14-15 in.) of rain in much of the state. Iowa also had above-average rainfall in both months, resulting in the twenty-second wettest June and nineteenth wettest July on record. An es - were at Eagle Lake, Kossuth 23 May (PH, CJF). Missouri's only Nelson's Sparrow was at Eagle Bluffs 9-10 May (GC, BJ, Joseph Bieksza, Eric Fishel), while 3 at Sedan Bottoms, Appanoose 23 May made Iowa's sole report (TNJ). A few strag - gler sparrows were noted: a White-throated at Tower Grove Park, St. Louis City, MO 25 May (Pat Lueders); a White-crowned at Squaw Creek Park, Linn, IA 25 May (BSc); and a Dark-eyed Junco at Weston Bend S.P., Platte, MO 6 May (Ginny Culver, Gareth Johnson). A Summer Tanager in Carter set a new early arrival date by one day 10 Apr (MeR), and the first Scarlet Tanager was the second earliest re - cord for Missouri at Red Bridge Rd., Christian 9 Apr (DB). In Iowa, Ed Thelen had a male West - ern Tanager visit his yard for Dickinson yard for the second consecutive year, this spring 21 May (ph., †ET). A male Rose-breasted Gros - beak at Mystic, Appanoose was the second earliest record for Iowa 18 Apr (TNJ). A Blue Grosbeak at Hornersville Swamp, Dunklin 16 Apr was the third earliest for Missouri (TJ). Single Lazuli Buntings visited three sites in the w. half of the Region: near Glenwood, Mills, IA 25 Apr (ph., †JA); Jackson, MO 4 May (Jo - seph Mosley); and near Carroll, Carroll, IA 15 May (ph., †WT). An ad. male Painted Bunting was farther n. than expected at Swan Lake 5 May (†DC). Sixty-five Bobolinks at Neal Smith N.W.R., Jasper 11 May was highest count re - ported (KVS). Yellow-headed Blackbirds were found in twelve Iowa counties beginning 9 Apr at Water Works Park, Polk (JB); the high count of 70 came from Riverton 25 Apr (KDy). Rusty Blackbird high counts in Iowa included 220 at Errington Marsh, Polk 27 Mar (RLC) and 200 at Banner Flats, Warren 21 Mar (JG). Brewer's Blackbird was reported in six Iowa counties, with the first on 18 Mar at Errington Marsh, Polk (DTh), high counts of 35 in Marengo, Iowa 19 Mar (DCH) and 30 on at Banner Flats War - ren 21 Mar (JG), and the last at Colo Ponds, Story 24 Apr (MP). Great-tailed Grackles were confirmed to be nest-building in Iowa at a small wetland in Ring - gold 30 May (JN). The only Red Crossbill (Type 2) was heard calling 17 Apr in Boone, IA (SJD). In Iowa, a flock of 40-75 Common Redpolls was reported near Lime Springs, Howard 1-7 Mar (LR, RGo). Missouri's third Hoary Redpoll continued to be enjoyed by many observers at private residence in Adair, as well as 7 Common Redpolls, through 10 Mar (Frankie Cuculich, m.ob.). The only other Common Redpoll report in Missouri was from Daviess 22 Mar (SK). Pine Siskins were more numerous than last spring, with 19 reports in Iowa, including a high of 15 in Johnson 1 Apr (JLF), and the last was on 23 May at Algona, Kossuth (MCK). In Missouri, they stuck around through the entire season,
