Oreothlypis celata celata, O. c. orestera
Status: Common regular spring and fall migrant statewide. Rare casual winter visitor southeast.
Documentation: Specimen: celata, UNSM ZM6809, 5 May 1898 Beatrice, Gage Co; orestera, UNSM ZM 11930, 13 Sep 1911 Dawes Co.
Taxonomy: There are four subspecies recognized (Pyle 1997): lutescens, breeding and wintering coastal southeast Alaska to southern California, sordida, resident California Channel Islands, orestera, breeding in Rocky Mountains to southwest USA and west Texas, and celata, breeding from Alaska across southern Canada, wintering coastal southern California to South Carolina and Florida.
The only documented records of orestera for Nebraska are from banding stations operated by Bird Conservancy of the Rockies in 2015, and three specimens in UNSM collected in Dawes Co in fall 1911. Nine orestera were banded at Chadron SP, Dawes Co 17-24 Sep 2015 and two on 4-13 Oct 2016, and at Wildcat Hills NC, Scotts Bluff Co 4 Sep and 8 Oct 2015. The three UNSM specimens are ZM11930 (cited above), ZM 12005 collected 15 Sep 1911, and ZM12006 collected 17 Sep 1911. One orestera was observed at Wildcat Hills NC 10 Oct 2015. Many fall migrants in the Panhandle are brightly colored, especially yellowish underneath, and have gray crowns and napes which contrast with the greenish-olive back, thus resembling Nashville Warblers without eye-rings. These are probably orestera. Dunn and Garrett (1997) stated that orestera occurs in the Nebraska Panhandle in fall; it breeds as close as the Laramie Mountains in Wyoming (Faulkner 2010).
On 22 Sep 2015, six celata and five orestera were banded at Chadron SP, indicating that celata occurs in the Panhandle; it is the only subspecies expected statewide.
Although lutescens has not been documented in Nebraska, it breeds in the same general area as Cassin’s Vireo and Townsend’s Warbler, both of which are regular fall migrants through the western Panhandle in fall. A pale overall yellow bird with no pale areas on its underparts and an exquisite lemon-yellow eye ring but otherwise fitting the description of an Orange-crowned (see Dunn and Garrett 1997) was at Oliver Reservoir, Kimball Co 20 Sep 2002; it may have been an immature lutescens. A very yellow bird with yellow eye arcs at Wilderness Park, Lancaster Co 11 Oct 2017 also fitted the description of lutescens. A bird photographed and identified as lutescens was in Logan Co, Colorado, some 10 miles from Nebraska, 23 Nov 2015 (Mlodinow, eBird.org, accessed May 2018). There are 10 reports of lutescens in the northeast corner of Colorado in the period 17 Sep-23 Nov (eBird.org, accessed May 2018).
The type locality of O. c. celata is Omaha, Nebraska; it was collected by Thomas Say on the Long Expedition in 1819-1820 (AOU 1957, Sharpe et al 2001).
Spring: Apr 2 (UNSM ZM12004),3,3 <<<>>> Jun 1,2,3 (Tout 1947)
Migrants arrive fairly early, in mid- to late Apr, and most depart by the end of May, although there are later reports 7 Jun 1998 Funk WPA, Phelps Co, 12 Jun 2010 Crescent Lake NWR, Garden Co, and 14 Jun 1959 Boone Co. In the northwest, Rosche (1982) considered it an uncommon to fairly common migrant.
The Rocky Mountains subspecies orestera, fairly common in fall in the Panhandle, has been reported only once in spring, at Oliver Reservoir 28 May 2011.
- High counts: 100+ in the eastern Rainwater Basin 3 May 2001, 85 at Gering Cemetery, Scotts Bluff Co 1 May 2016, 50 in Hall Co 11 May 2002, and 49 in Sarpy Co 13 May 1995.
Fall: Aug 22,23,24 <<<>>> Nov 8,9,10
Early arrival dates are problematic, as fall individuals can be easily confused with immature Yellow Warblers and Tennessee Warblers. According to Gilbert et al (2010), orestera is an early fall migrant, arriving in mid-Aug, and celata is “notoriously late”, arriving late Sep. Thus, reports in the west before mid-Sep are expected to be orestera: 19 Jul 1977 Keith Co, “probably … a very early autumn transient” (Rosche 1994), 12 Aug 1974 Scotts Bluff Co, 14 Aug 1973 Sioux Co, and 18 Aug 2011 Sioux Co. Easterly records in the central at dates that suggest orestera are: 28 Jul 1999 Funk WPA, and two “very yellow” birds in Clay Co Sep 2000 (Jorgensen 2012). There are early eastern dates that are likely early celata: 27 Jul 2000 Wehrspann Lake, Sarpy Co, 11 Aug 1987 Douglas Co, 14 Aug 1987 Dakota Co, 15 Aug 1985 Lancaster Co, and 18 Aug 2008 Fontenelle Forest, Sarpy Co. Only the latter report is documented.
This species is one of the last warblers to leave in fall. There are later dates 12 Nov 1981 Douglas-Sarpy Cos, 25 Nov 2017 Sarpy Co, 4 Dec 2002 Bellevue, Sarpy Co, 11 Dec 2009 Lancaster Co, 17 Dec 2002 Omaha, Douglas Co, 18 Dec 1998 Harlan Co Reservoir CBC, 18 Dec 1999 Lincoln CBC, 21 Dec 1957 Scottsbluff CBC, and 21 Dec 1996 Lincoln CBC.
- High counts: 50+ in Thomas Co 30 Sep 2001, 50+ at North Platte, Lincoln Co 4 Oct 2010, 45 at Arbor Day Farm, Otoe Co 26 Sep 2000, and 42 in the eastern Rainwater Basin 27 Sep 1999.
Winter: Most unexpected was one photographed at Conestoga Lake, Lancaster Co 27-28 Feb 2016, the first documented Jan-Feb record for Nebraska. Whether it wintered in the vicinity or was a very early migrant is conjectural. A rather amazing record was of one first noted at a Lincoln residence 9 Dec 2017, and, presumably the same bird, was found dead after a spell of very cold weather 1 Jan.
It was described as “wintering as far north as Omaha” in 1979-80 (Williams 1980) but no details were given. Orange-crowned Warbler normally winters north only to Oklahoma and Arkansas; there are “at least 11” counties in Kansas that have Feb records, and there is a single record of over-wintering (Thompson et al 2011).
