YELLOW-BREASTED CHAT

Icteria virens virens, I. v. auricollis

Status:  Uncommon, locally common, regular breeder and spring and fall migrant west and central, rare casual elsewhere.

Documentation:  Specimens: auricollis, UNSM ZM6909, 3 Jun 1901 Monroe Canyon, Sioux Co; virens, UNSM ZM10757, 15 May 1909 Roca, Lancaster Co.

Taxonomy: Recent genetic studies resulted in elevation of this species to its own family, Icteriidae; it is no longer considered a member of Parulidae (Chesser et al 2017).

There are two subspecies recognized (Eckerle and Thompson 2001): auricollis, breeding from the western Great Plains (including southern Saskatchewan) and west Texas westward, and virens, breeding in the eastern portion of the range, from the eastern Great Plains (northeast South Dakota; AOU 1957) and central Texas (Fort Worth, Houston; AOU 1957) eastward.

Both subspecies breed in Nebraska, although the breeding population in southeast Nebraska, presumably virens, has declined in recent years and may have been extirpated (see Summer).

Changes since 2001: This species was essentially extirpated from the southeast by 2000, but since then reports have increased. Of 27 southeasterly reports for May-Jul since 1981, 22 have been since 2008.

Spring:  Apr 25,26,28 <<<>>> summer

Spring migrants arrive in late Apr and are common in the west, but there are few reports in the east. Some of the few recent reports in the east may be of western auricollis; although there is no recent information as to the subspecies identification of recent eastern sightings, there are two old specimen records of auricollis in the east: one (UNSM ZM6912) from Adams Co 10 May 1919 (Jorgensen 2012), and another (HMM 2634-A) from Clay Co 18 May 1920 (Jorgensen 2012; Swenk 1940).

Recent increases in the number of eastern reports suggest a return of virens to its former range, although there is no documentation as yet of the subspecies involved. One in the observer’s Dixon Co yard 21 May 2009 was the first there since 1996 (Jan Johnson, pers. comm.), one was at Arbor Day Farm, Otoe Co 8 May 2011, and one in Dakota Co 28 May 2013 was the veteran observer’s first for that county (Bill F. Huser, pers. comm.). In 2014 there was a surprising influx: singles were in Omaha, Douglas Co 16 May, southeast Washington Co 18 May, and 1-2 were at Indian Cave SP, Nemaha and Richardson Cos 30 May and 1 Jun. In 2015 also, several were reported: 21 May Stanton Co, 17 May Platte Co, and 11 May Douglas Co. One was in Lancaster Co 14 May 2016, and in 2018 singles were in Lincoln, Lancaster Co 15-16 May and at Wood Duck WMA, Stanton Co 11 May.

  • High counts:  14 in Sowbelly Canyon, Sioux Co 16 May 2018, 9 there 21 May 1996, and 7 in Carter Canyon, Scotts Bluff Co 17 May 2003.

Summer: This species was formerly considered to be most common in the eastern part of the state; Bruner et al (1904) listed it as “abundant” along the eastern edge. By 1958, Rapp et al (1958) described the species as fairly common throughout, but most numerous in the east, especially in the Missouri River Valley, but also in the valleys of the Little Blue and Elkhorn rivers (Swenk 1940). As late as the 1970s, it was distributed statewide (Johnsgard 1979), but at about that time eastern breeding locations became scattered and it was only locally common.  Since the 1970s, the species has declined to near extirpation in the east (Sharpe et al 2001).  Although Ducey (1988) has proposed that destruction of nesting areas along the Missouri River due to riverside development as a cause for this decline, an additional explanation is that this eastern population, presumably virens, has experienced limiting factors that has reduced numbers in its wintering range similar to those experienced by other eastern neotropical migrants (Terborgh 1989). Chat numbers in eastern Kansas declined to near-absence by 1992 (Thompson et al 2011).

As noted above (see Spring), reports in the southeast have increased in recent years. Since 1981 there have been 17 reports for Jun and Jul, 12 of these since 2008.

The situation in the east is in strong contrast with the Panhandle and north; chats are locally common throughout the western half of the state, eastward in the Niobrara River Valley to Rock Co (James E. Ducey, pers. comm.) and Knox Co, where it is uncommon, with recent records 8 Jun 2005, 9 Jun-16 Jul 1990, six on 9 Jul 2008, and 22-29 Jul 1989. There is a recent report 10 Jun 2015 at Bow Creek WMA, Cedar Co. Chats are reported every year in the eastern Niobrara River Valley (Brogie and Mossman 1983, Rosche 1982).  This species is “increasing every year” in Scotts Bluff Co as of 2017; 12 were counted along Old Stage Road 8 Jul 2017, and 16 were at Soldier Creek Wilderness, Sioux Co 19 Jun 2017.

Yellow-breasted Chat is common in the southwest and Republican Valley, with concentrations around the southwestern reservoirs, especially Red Willow Reservoir, Frontier Co, but is rare east as far as Harlan Co. Recently, three birds were found 12 Jun 1999 along the south side of Harlan Co Reservoir, and singles were there 6 Jul 2009, 27 Jun 2015, 1 Jun 2017, and two birds west of Alma 7 Jul 2007 were at “the only reliable spot in the county” (Glen and Wanda Hoge, pers. comm.). Four were at the latter location 26 Jun 2008 and five on 25 Jun 2011. Significant were sightings as far east as Red Cloud and Inavale in Webster Co 7 Jun 2009.

  • Breeding phenology:
    Nest building: 8-10 Jun
    Eggs: 3 Jun- 6 Jul
    Fledglings: 3 Jul

Fall:  summer <<<>>> Oct 6,6,9

Departure is protracted, with most birds gone by early Oct, but there are later dates 16 Oct 1961 Cass Co and 27 Oct 1960 Cass Co.

Recent mid-late Jul reports in the southeast may be early migrants from breeding locations (Eckerle and Thompson 2001); these are 16 Jul 2008 Otoe Co, 21 Jul 2003 DeSoto NWR, Washington Co, 21 Jul 2000 extreme southwest Saunders Co, 25 Jul 1997 Merrick Co, 25 Jul 2015 Lancaster Co, and 28 Jul Antelope Co. There are these few easterly fall reports since the 1980s: 3 Sep 2000 Smartweed WMA, Nuckolls Co (Jorgensen 2012), 10 Sep 2000 Summit Reservoir, Burt Co, 13 Sep 2017 Nuckolls Co, 14 Sep 2014 Dixon Co, and 6 Oct 2014 Saunders Co.

A specimen of auricollis that had probably died 26 Sep 2018 was picked up on the University of Nebraska-Lincoln campus 28 Sep 2018 (Thomas Labedz, pers. comm.).

  • High counts: 8 in Carter Canyon 1 Sep 2000, 4 at Chadron SP, Dawes Co 8 Sep 2015, and 4 at Chadron SP 1-2 Sep 2017.
