Single Pine Warblers were in Shimek, Lee 18 & 24 Jun (CE, MP), where they are a rare breeder, and in nearby Shimek, Van Buren 19 Jul (SJD). Up to 4 Spotted Towhees were at Oak Grove P., Sioux, IA 11-28 Jun (m.ob.) where the species nested in 2015. Clay-colored Sparrows continued to expand their range across n. Iowa with reports from eight coun - ties east to Howard (m.ob., eBird). Henslow's Sparrows were found throughout Iowa with 15 at Neal Smith N.W.R., Jasper 8 Jun (KVS) the most. Single White-throated Sparrows in Black Hawk 5 Jun (Connor Langan) and in Linn 18 Jun (Billy Reiter-Marolf), both in Iowa, were unexpected. A Rose-breast - ed Grosbeak at Trail of Tears S.P., Cape Gi- rardeau 27 Jul (MH, Mark Hahn) was south of its usual Missouri range. Blue Grosbeaks had a record year in Iowa with reports from 26 counties. Besides reports from its w. Iowa stronghold and numerous reports from cen. and e. Iowa, a few were in Cerro Gordo, Floyd, Worth, and Winnebago in n.-cen. Iowa near the Minnesota border (m.ob.). Bobolinks were found south to Ringgold, IA (eBird) near the Missouri border and Har - rison, MO with counts at Dunn Ranch of 90 on 5 Jun (LW, m.ob.) and 54 on 15 Jul (Jane Capozzelii). At their southern outpost in nw. Missouri, Yellow-headed Blackbirds were rare, presumably because of changes in habitat availability (fide Mark Robbins) and, with the dry conditions, only 3 were at Squaw Creek on 8 Jul (Kent Fiala). Away from the Missouri River, one was along the Thompson River, Chariton 26 Jun (SK). Great-tailed Grackles were found scattered across both states with 120 on 31 Jul at Hedman Lake/England Pond, Dade, MO (David Blevins) the most.

Loggerhead Shrikes were reported in 10 Iowa counties, mostly in the southern half of the state. Other than one at Saylorville 27 Jul (SJD), all of Iowa's White-eyed Vireos were in se. Iowa (m.ob.). Iowa's only Red-breasted Nuthatch was one near Iowa City, Johnson 24 Jun (eBird). Iowa Brown Creepers were mostly along the Mississippi River from Allamakee to Des Moines with the most being 5 on 1 Jun at Huron Island, Des Moines (eBird, KM). The 50 House Wrens at Loess Bluffs 30 Jun (PL) was a high count. An ad. Winter Wren with 2 fledglings in Jones 19 Jun (CE) represents Iowa's first nesting record since 1988. Late- summer Sedge Wrens in Iowa were several in Ringgold near the Missouri border 12-30 Jul (eBird). Several species normally rare even in s. Iowa seemed to be found further north than usual with Carolina Wrens in Plymouth and Winneshiek (eBird), a Northern Mock - ingbird in Worth 30 Jul (PH), and Summer Tanagers in Sioux and Winneshiek (DA, eBird). Iowa's 11 reports of Veerys were more than usual and other than one in Waubonsie S.P., Fremont 2 Jun (JJ) in sw. Iowa, were mostly from ne. Iowa (m.ob., eBird). The region's lat - est Swainson's Thrushes were 2 in Marshall, IA 4 Jun (MP). A flock of 105 Cedar Wax - wings in Polk City, Polk, IA 1 Jun (AB) was unusual for that date. Three Red Crossbills in Cherokee, IA 3 Jun (Dick Bierman) were the last of continuing birds from spring. Late Pine Siskins in Iowa were 4 until 12 Jun in Cerro Gordo (Betty Lucas) and 2 in Davenport, Scott 18 Jun (Walt Zuurdeeg). WARBLERS THROUGH BLACKBIRDS Late warblers in Iowa, all singles, were a Northern Waterthrush in Johnson 3 Jun (JF), a Bay-breasted Warbler in Jackson (KM), and Pine Warbler in Lake City, Calhoun (Freder - ick Ruckersfeldt), both on 2 Jun. A singing male Blue-winged Warbler at Poosey C.A., Livingston, MO 1 Jun (SK) was north of its main breeding range in the e. Ozarks. The 35 Prothonotary Warblers at Huron Island, Des Moines, IA 1 Jun (KM) was a high count. An ad. and 2 yg. at West Okoboji Lake, Dick - inson, IA 22 Jul (eBird, Neil Bernstein) were far from that species' usual haunts along the Mississippi River. An ad. and a juv. Nashville Warbler in Polk, IA 27 Jul (SJD) were early southbound birds. Rare in the region, two Hooded Warblers in St. Louis, St. Louis 20 Jun (PL) were at the northern edge of that bird's Missouri range and singles in Shimek, Van Buren 10 Jun (DT) and Shimek, Lee 18 Jun (CE) were in se. Iowa where the species is rare but regular. Two singing male Chestnut- per fide SJD). Missouri's largest heron colony was in a small, difficult-to-access woodlot in St. Louis City where about 450 birds were found. Little Blue Herons were the most abundant followed by Snowy Egrets and Cat - tle Egrets (Andrea Shuhmann). Other wad- ing bird concentrations were 85 Great Egrets at Swan Lake N.W.R., Chariton, MO 27 Jun (SK), 6 Little Blue Herons in Forest Park, St. Louis City 13 Jun (PL), and 3 in Fremont, IA 3 Jun (PR), and 20 Cattle Egrets near St. Joseph, Buchanan, MO 2 Jun (LL) and 56 in Fremont 3 Jun (PR). One or 2 Yellow-crowned Night- Herons were at three sites in Iowa (m.ob.). Numerous Ospreys were seen in Missouri, mostly in June, but one at Eagle Bluffs 24 Jul (BJ) was thought to be a vagrant or early fall migrant. In Iowa, 22 of 24 Osprey nests were successful and produced 41 young (PS). Mississippi Kites continued to expand their nesting range in Missouri, especially in urban areas of Columbia, Kansas City, and St. Louis (m.ob.). Iowa's Mississippi Kites were at their usual sites with 2 in Wapello 18 Jun (MP) and 3 in Polk 28 Jun (AB). A female Sharp- shinned Hawk in Maryville, Nodaway 20-24 Jun & 23 Jul (DE) was unusual for nw. Mis - souri. Iowa's Swainson's Hawks were singles in Clay 4 Jun & 14 Jul (LS, DA) and in Kos - suth 12 Jun (Matt Kenne). Barn Owls had a great year in Iowa with nesting attempts at 16 sites in 13 coun - ties, mostly in s. Iowa. At least 29 yg. were fledged, a record high (Bruce Ehresman). Several sightings of a Short-eared Owl at Neal Smith N.W.R., Jasper (KVS) constituted Iowa's third and the region's fourth summer report in the last 10 years. Besides the usual reports from n. Iowa, Yellow-bellied Sapsuckers were found south to Jackson with 10 at the Upper Mississippi River N.W.R. 15 Jul (KM). It was a historic year for Merlin with Io - wa's first nests since 1908. One in Iowa City, Johnson produced 5 yg. (m.ob.) and a second in Waterloo, Black Hawk fledged 3 yg. (TS). Iowa's Peregrine Falcons had a good year with 14 successful nests producing 36 yg., totals similar to those in 2015 (PS). FLYCATCHERS THROUGH FINCHES Late flycatchers in Iowa were an Olive-sided Flycatcher in Grundy 16 Jun (MP) and a Yel - low-bellied Flycatcher and an Alder Flycatch- er, both in Sioux 18 Jun (DA). Nine Willow Flycatchers at Dunn Ranch, Harrison, MO 5 Jun (LW, m.ob.) made for a high count for that location. Nesting was confirmed there 16 Jul (ph. Lisa Owens). Further evidence of the eastern range expansion of Scissor-tailed Fly - catcher came with four yg. found along Darst Bottom Rd., St. Charles, MO 29 Jun (ph. Tom -
