Setophaga americana
Status: Fairly common regular spring migrant east, uncommon east-central, rare west-central, rare casual west. Uncommon regular breeder east. Uncommon regular fall migrant east, rare casual central and west.
Documentation: Specimen: UNSM ZM6817, 20 Apr 1901 Havelock, Lancaster Co.
Taxonomy: No subspecies are currently recognized (Gill et al 2022), although Pyle (1997) listed two: ludoviciana, breeding in the western part of the range, and americana, breeding eastward. Apparently, these are not easily separable morphologically; they were differentiated on the basis of vocalizations (Moldenhauer and Regelski 2020).
Nebraska birds are ludoviciana (Dunn and Garrett 1997), if subspecies are recognized.
This species and Cerulean Warbler (S. cerulea) are closely related, with similar plumage, song, and behavior, have hybridized, and been considered conspecific (Moldenhauer and Regelski 2020). An Iowa example of a hybrid is at eBird Checklist – 13 May 2017 – Wildcat Den SP). There are no Nebraska records of this hybrid. See Comments, below.
Northern Parula also hybridizes on occasion with Yellow-throated Warbler (S. dominica); there are records for Wyoming and Iowa (eBird.org, accessed Jul 2023).
Spring: Apr 11, 11, 12 <<<>>> summer
Arrival is early, typical of the southern warbler species which breed in Nebraska. There appears to be a small movement up the Missouri River Valley in spring; Northern Parula is a rare migrant in eastern South Dakota (Tallman et al 2002).
There are numerous reports in the Panhandle; these are in the period 21 Apr- 3 Jun.
- High counts: 20-25 at Fontenelle Forest, Sarpy Co 1 May 2008, 20 at Indian Cave SP, Nemaha and Richardson Cos 30 Apr 2011, 17 at Fontenelle Forest 23 Apr 2009, 17 there 29 Apr 2010, and 17 at Indian Cave SP 1 May 2015.
Summer: Northern Parula is a low-density summer resident in large forest tracts in the Missouri River Valley, north occasionally to Thurston Co; it occurs primarily in riparian forests, but uses a relatively broad range of woodland types for breeding (Moldenhauer and Regelski 2020) and often occurs in upland areas, especially at Indian Cave SP. Northern Parula has been reported regularly since the 1960s, mostly from southeast Washington Co south, although it was first reported as far north as Thurston Co 13 Jun 1998 and nested there in 2006, when a pair was incubating eggs 13 Jun (Huser, Probst; Mollhoff 2022).
Northern Parula is one of a few southeastern US wood warbler species for which reports are increasing northwest of the traditionally recognized ranges in Nebraska as field work explores new northwesterly locations with appropriate habitat, although may also be an artifact of increasing observer activity since the inception of eBird. As long ago as 1919, it was described as an “uncommon migrant eastwardly” (Swenk 1919). Short (1965) collected a singing male in Brown Co 21 June 1964, and it was reported there 12 Jun 1972 and 7 Jul 1968, but not in 1982 (Brogie and Mossman 1983). One was singing at Valentine, Cherry Co 4 Jul 1998 and another was nearby at Valentine NWR 11-12 Jul 2006. In 2021, 1-2 were at Fort Falls, Cherry Co through 23 Jun, and in 2023 one was recorded at Smith Falls SP, Cherry Co 5 Jun, possibly a migrant. A singing male was at Oak Valley WMA, Madison Co 10 Jun 2022.
BBS data 1966-2013 (Sauer et al 2017) show this species increasing in eastern Kansas and extreme southeast Nebraska at >1.5% per year.
The few confirmed breeding records include young being fed in Sarpy Co in 1986 (Bennett 1987), 5 Sep 1991 (Grzybowski 1992) and 20 Aug 2004, and adults were tending a juvenile at Fontenelle Forest 28 Jun 2003 (Silcock 2003). Mollhoff (2016) showed breeding season reports in the Missouri River Valley in Richardson, Nemaha, Cass, Sarpy, Washington, and Thurston Cos 2006-2011. It was “quite common,” with up to six at Indian Cave SP, Richardson Co during Jun 1995.
Away from the Missouri River Valley locations, there are reports in the southeast in southwestern Richardson Co and southern Gage Co, the latter at Barneston 30 Jun 2010. Singles were in Jefferson Co 3 Jun 2007 and at Fairbury City Park, Jefferson Co 5 Jun and 3 Jul 2021. One was recorded in Lincoln, Lancaster Co 11 Jun 2022, and there have been consistent reports from the Wilderness Park location at 1st & Calvert St., Lancaster Co since 1999 (Moni Usasz, personal communication).
The only summer records farther west are of a singing male at Chadron, Dawes Co 5 Jun 1979 (Rosche 1982), 10 Jun 2011 Chase Co, Ash Hollow SHP, Garden Co 26 Jun 2010, and three in McCook, Red Willow Co 6 Jun. Some of these reports, especially in early Jun, may be of migrants.
- Breeding phenology:
Eggs: 13 Jun
Nestlings: 27-28 May
Fledglings: 28-30 Jun
Fall: summer <<<>>> Oct 2, 2, 4; Sep 3, 4, 4 <<<>>> Oct 4, 7, 8 (away from breeding areas)
An earlier date away from breeding areas is 16 Aug 2022 Nance Co.
Later dates away from breeding areas are 17 Oct 2022 Kimball Co, 7 Nov 2021 Dundy Co, and 17 Nov 2023 Sarpy Co.
Northern Parulas become inconspicuous in late summer and fall, and depart by late Sep.
There are these few fall reports away from the east: 30 Jul-28 Aug 1977 Box Butte Reservoir, Dawes Co, 5 Sep 1979 Boone Co, 6 Sep 1998 male at Gering Cemetery, Scotts Bluff Co, 7 Sep 1912 specimen UNSM ZM11790 Thomas Co (Zimmer 1913), 12 Sep 1919 specimen UNSM ZM6840 Sioux Co, 20 Sep 2022 Scotts Bluff Co, 22 Sep 1997 Thomas Co, 26 Sep 2023 Scotts Bluff Co, and 30 Sep 2014 Dawson Co.
Occasionally very tardy individuals occur, oddly all in the west or west central: one at Gotte Park, Kimball Co 17 Oct 2022, one at Rock Creek SRA, Dundy Co 7 Nov 2021, an immature male photographed in Keith Co 4 Dec 1999 (Jorgensen 2001), and an apparent immature at Bridgeport, Morrill Co for about two weeks prior to 23 Dec 2023.
- High counts: 4 in Washington Co 11 Sep 1995, 4 in Washington and Douglas Cos 13 Sep 1998, and 4 on Plum Creek Trail, Seward Co 9 Sep 2018.
Comments: As Cerulean Warbler has declined in Nebraska in recent years, doubt has been raised by Justin Rink (personal communication) that heard only singers identified as Ceruleans at Indian Cave SP may in fact be Northern Parulas; all “odd” singers that might have been Ceruleans were tracked down and found by Rink to be Northern Parulas. Some or perhaps all of these “odd” songs may be an alternate Northern Parula song that Pieplow (2017) describes as a “second-category song”. This frequently heard two-part song consists of buzzy series of notes with the initial series lower in pitch than the succeeding series so sounds quite similar to a Cerulean’s song (Shari Schwartz; personal communication, eBird.org). On the other hand, “odd” songs do occur; one such singer, whose song consisted of a series of paired buzzes on the same pitch, was seen and heard in the same place at Indian Cave SP for two consecutive springs 2004 and 2005 (Paul Lehman, Ross Silcock; Silcock et al 2005).
