YELLOW-BELLIED SAPSUCKER

Sphyrapicus varius

Status:  Uncommon regular spring migrant east and central, rare casual west. Fairly common fall migrant east, uncommon central, rare west. Rare regular winter visitor southeast, rare casual elsewhere.

Documentation:  Specimen: UNSM ZM6307, 9 Oct 1921 Lancaster Co.

Taxonomy: No subspecies are currently recognized.

Yellow-bellied, Red-naped (S. nuchalis), and Red-breasted (S. ruber) Sapsuckers are closely related, having diverged genetically from each other relatively recently. AOU (1957) treated them as subspecies of Yellow-bellied Sapsucker, but they have each been more recently considered full species (Walters et al 2002).

It should be noted that reports from western Nebraska in the 1980s, prior to the split to three species, included Red-naped as a subspecies of Yellow-bellied.

Changes Since 2000: The number of reports during fall migration and winter and in western and central Nebraska has increased remarkably since 2000. There is a total of 30 reports for Dec-Feb in central Nebraska; 25 of these have occurred since 2000.  Of a total of 96 sapsuckers counted on CBCs 1967-68 through 1992-93, only five (5%) were north and west of Kearney and DeSoto NWR, but in the six CBC years 2010-2015, 11 of 57 (19%) were north and west of those locations. An indication of how much the status has changed in the last 20 years is this statement from the 1995 Spring Seasonal Report in Nebraska Bird Review (Silcock 1995): “An uncommon migrant, mainly in the Missouri River Valley, … Another was rather westerly and rather late in Saline Co….”.

Spring:  winter <<<>>> May 1, 1, 1

Migration peaks in late Mar and early Apr. Arrival of migrants is difficult to discern, especially in the southeast, due to the presence of wintering birds, but the earliest migrants probably appear around 10-15 Mar. One was in Garfield Co 9 Mar 2016. Early spring dates in South Dakota are 19-28 Mar (Tallman et al 2002).

There are 14 later reports statewide through 6 Jun 1972 Lancaster Co, 9 Jun 1957 Hall Co, 30 Jun 2001 Lancaster Co, and 1 Jul 1993 Sarpy Co.

Spring migrants are far less numerous westward than in fall. In the Panhandle, there are only about 14 spring reports, in the period 7 Mar-21 May.

There is no evidence for summering or nesting in Nebraska, even though this species nests in extreme southeastern South Dakota (Tallman et al 2002) and recently in northwest Iowa (Kent and Dinsmore 1996).

Fall:  Sep 18, 19, 20 <<<>>> winter

There are earlier dates 25 Aug 1981 Lancaster Co, 31 Aug 2015 in Lincoln, Lancaster Co, 1 Sep 1967 Cass Co, and 15 Sep 2012, a juvenile at Fontenelle Forest, Sarpy Co.

Migrants appear in mid to late Sep, and, in the west, are more frequently reported than in spring. Although some older western reports probably are referable to Red-naped Sapsuckers, recent years have seen an increase in westerly sightings of Yellow-bellied Sapsuckers, and the likelihood is that in fall the majority of western sapsuckers currently (2017) are indeed Yellow-bellieds.

Peak movement is in the first half of Oct, but by the time of the CBC period in mid-late Dec, most sapsuckers are in the southeast.  CBC data suggest that westerly sightings have increased in recent years; of a total of 96 counted on CBCs 1967-68 through 1992-93, only five (5%) were north and west of Kearney, Buffalo Co and DeSoto NWR, Washington Co, but during 2010-2015, 11 of 57 (19%) were north and west of those locations. Highest CBC counts are eight at Tristate (at Arbor Lodge SHP) 1981-82, seven in Omaha 1979-80, and six at Branched Oak Lake-Seward 16 Dec 2012.

Reports were numerous in fall 2015, when at least 40 individuals were reported, notably 11 in a trip through Boone, Platte, and Nance Cos 3 Oct and seven in about five hours’ birding in Fillmore, Thayer, and Jefferson Co the same day. Almost all of the reports were from the east, but singles were in Custer Co 16 Oct and 28 Nov, the latter an immature.

  • High counts:  11 in a sweep through Boone, Platte, and Nance Cos 3 Oct 2015, 3 at Wyuka Cemetery, Lincoln, Lancaster Co 14 Oct 1996 and 3 at Branched Oak Lake, Lancaster Co 5 Nov 2012.

WinterWintering birds occur in the southeast in varying numbers. In the winters 2000-2001 through 2014-2015, CBC data show 21 in 2004-2005 as the high total for the state, and low a single bird in 2002-2003; the average for the 10 winters with numbers cited was 9.6. Most reports for Dec-Feb are in Dec, declining through Feb; in 2003-2004, 15 were counted, nine in Dec, four in Jan, and two in Feb.

There are 39 records for Dec-Feb in the central, about half of these in Dec and the remainder evenly spread through Jan-Feb. No fewer than 34 of the 39 records have occurred since 2000. There are only these Dec-Feb reports from the Panhandle: 1 Jan 1977 Sioux Co, 4 Jan 1982 Scotts Bluff Co, 10 Jan 1976 Scotts Bluff Co, and 18 Feb 2010 an immature male in Cheyenne Co.

Comments: Red-breasted Sapsucker (S. ruber) is a related species that occurs along the Pacific Coast of North America.  A sapsucker with a “red head and breast” was observed near Odessa, Buffalo Co 29 Mar 2004 but could not be relocated. It seems most likely to have been a variant Yellow-bellied Sapsucker, although a male Red-breasted Sapsucker was photographed in Pottawattamie Co, Iowa, 6 Dec 2006 (http://iowabirdrecords.org/Reports/Accepted.aspx).

A bird in Hall Co 5 Mar 2007 was well-described, including no apparent hybrid characters, and identified as a Red-naped Sapsucker by an experienced observer. This is an early and easterly report for that species; it may also have been a variant Yellow-bellied Sapsucker or an intergrade of the two species.

A juvenile male collected at Chadron, Dawes Co 23 Sep 1919 (UNSM ZM6312), labeled as a Red-naped Sapsucker, is more likely a Yellow-bellied; see discussion in the Red-naped Sapsucker account.
