DOWNY WOODPECKER

Dryobates pubescens medianus, D. p. leucurus

Status:  Common regular resident east and central, fairly common west.

Documentation:  Specimen: UNSM ZM12374, 25 Nov 1893 Lancaster Co.

Taxonomy:  There have been several recent changes in generic assignment of woodpeckers. Dryobates includes species previously assigned to Dendrocopos and Picoides (Fuchs et al 2015, Gill and Donsker 2017, Chesser et al 2018); these species are Nuttall’s, Ladder-backed, Downy, Crimson-crested, and Lesser Spotted Woodpeckers. The latter two are Eurasian in distribution.

There are seven subspecies recognized (Pyle 1997, Gill and Donsker 2017), fumidus, gairdnerii, and turati of the Coastal Pacific, glacialis and leucurus of the Interior West, and medianus and pubescens in the Eastern US.

In Nebraska, two subspecies occur; eastern medianus breeding over most of the state, and the Rocky Mountain subspecies leucurus possibly breeding (Haecker et al 1945) in the extreme northwest. A leucurus was studied at Fort Robinson SP, Dawes Co 18 May 2018; it was with an apparent medianus. Subspecies medianus has spread westward in Nebraska during the 20th century in river valleys, resulting in contact of the two subspecies; Ford collected an intermediate specimen (KU 34088) five miles north of Harrison, Sioux Co on 18 Jul 1957 (Ford 1959). Currently, leucurus may only be a winter disperser in low numbers to northwestern Nebraska; it only occurs rarely in winter on the eastern plains of Colorado (Andrews and Righter 1992) and at Barr Lake, Colorado, Oct to mid-May, where the local breeding birds are “the eastern subspecies”, (medianus; Andrews et al 2002).

Medianus and leucurus are identifiable in the field; leucurus has little or no white spotting on the greater wing-coverts (“shoulders”) and less black in its outer rectrices (Jackson and Ouellet 2002).

Intriguing was the appearance in three consecutive winters of a Downy Woodpecker with a yellow (rather than red) nape in a Scotts Bluff Co yard Feb and fall of 2010, Mar 2011, and 24-25 Nov 2012 (Ann Duey, personal communication; photo). It had minimal white markings on its shoulders, suggesting Rocky Mountain provenance. According to Jackson and Ouellet (2002), “males occasionally grow a yellowish (not red) nape- or forehead-patch”.

Resident: BBS data indicate highest numbers in the east, with numbers very low in the west. Bruner et al (1904) considered this species very common in the eastern third of Nebraska around 1900, but rare and local in the western half of the state. Ducey (1988) shows no breeding records in the central prior to 1920.

  • Breeding Phenology:
    Eggs: 8-23 May
    Nestlings: 25 May-2 Jul
    Fledglings 14 Jun
  • High Counts:  25 at Fontenelle Forest, Sarpy Co 2 Apr 2010, 17 there 1 Apr 2017, and 12 in Cass Co 3 Apr 2017.

Winter distribution resembles that in summer, according to CBC data. Bent (1939) and Browning (1995) noted that there is little or no evidence for movement of Downy Woodpeckers. Some wandering and possible influx of leucurus may occur in the west however (see Taxonomy); Rosche (1982) considered Downy Woodpecker more common in the northwest in winter than in summer.

Highest CBC counts include 191 at Omaha in 1977-78 and 175 there in 1981-82. Highest CBC counts in the west are 29 at Crawford in 1977-78 and 20 at Scottsbluff in 1976-77.
