Red-naped Sapsucker - Sphyrapicus nuchalis
FWP Conservation Tier
Call a nasal or mewing "cheerrr" or "meeah" like Yellow-bellied Sapsucker; typical drumming pattern is a burst of several rapid thumps followed by several slow, rhythmic thumps (Peterson 1990, Howell and Webb 1995). Like other sapsuckers, leaves distinctive sign in horizontal rows of small, squarish sap wells around tree trunks, especially in broad-leaved trees. See Devillers (1970) and Dunn (1978) for detailed information on identification. Small to medium woodpecker; length 19 to 21 cm; mass 32 to 66 g. Black bib on upper breast, prominent red forehead with black band at rear, nape red, black stripe along side of head bordered by 2 white stripes, crown and nape black, large white wing-patch, back blackish, rump white, and underparts buffy or yellow-tinged. Male: throat red. Female: chin and upper throat white, lower throat red (Walters et al. 2002).

In Bozeman area, normal migration periods are May 8 to 20 and September 5 to 20, with no peak dates (Skaar 1969).
Birds have a strong preference for nesting in broken-top larch; optimum habitat is old-growth larch, particularly near wet areas. Excavates a new cavity each spring. Breeds in deciduous and mixed woodlands including aspen groves in open ponderosa pine forests, aspen-fir parklands, logged forests where deciduous groves remain, aspen groves in open rangeland, birch groves, montane coniferous forests and occasionally subalpine forest edges (Walters et al. 2002).
Ecological Systems Associated with this Species
- Details on Creation and Suggested Uses and Limitations
How Associations Were Made
We associated the use and habitat quality (high, medium, or low) of each of the 82 ecological systems mapped in Montana for
vertebrate animal species that regularly breed, overwinter, or migrate through the state by:
- Using personal observations and reviewing literature that summarize the breeding, overwintering, or migratory habitat requirements of each species (Dobkin 1992, Hart et al. 1998, Hutto and Young 1999, Maxell 2000, Foresman 2001, Adams 2003, and Werner et al. 2004);
- Evaluating structural characteristics and distribution of each ecological system relative to the species’ range and habitat requirements;
- Examining the observation records for each species in the state-wide point database associated with each ecological system;
- Calculating the percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system to get a measure of “observations versus availability of habitat”.
Species that breed in Montana were only evaluated for breeding habitat use, species that only overwinter in Montana were only evaluated for overwintering habitat use, and species that only migrate through Montana were only evaluated for migratory habitat use.
In general, species were associated as using an ecological system if structural characteristics of used habitat documented in the literature were present in the ecological system or large numbers of point observations were associated with the ecological system.
However, species were not associated with an ecological system if there was no support in the literature for use of structural characteristics in an ecological system, even if
point observations were associated with that system.
High, medium, and low habitat quality was assigned based on the degree to which the structural characteristics of an ecological system matched the preferred structural habitat characteristics for each species in the literature.
The percentage of observations associated with each ecological system relative to the percent of Montana covered by each ecological system was also used to guide assignments of habitat quality.

Suggested Uses and Limitations
Species associations with ecological systems should be used to generate potential lists of species that may occupy broader landscapes for the purposes of landscape-level planning.
These potential lists of species should not be used in place of documented occurrences of species (this information can be requested at: http://mtnhp.org/requests/default.asp
) or systematic surveys for species and evaluations of habitat at a local site level by trained biologists.
Users of this information should be aware that the land cover data used to generate species associations is based on imagery from the late 1990s and early 2000s and was only intended to be used at broader landscape scales.
Land cover mapping accuracy is particularly problematic when the systems occur as small patches or where the land cover types have been altered over the past decade.
Thus, particular caution should be used when using the associations in assessments of smaller areas (e.g., evaluations of public land survey sections).
Finally, although a species may be associated with a particular ecological system within its known geographic range, portions of that ecological system may occur outside of the species’ known geographic range.

Shrubland, Steppe and Savanna Systems
Creates sap wells in the bark of woody plants and feed on sap that appears there. When Red-naped Sapsuckers first arrive at their breeding areas, they often drill sap wells in the xylem of conifers and aspens. Once the temperatures increase and sap begins to flow, theses birds switch to phloem wellls in aspen or willow, if available. Insects, also bast (inner bark), fruit, and seeds (Walters et al. 2002).
Nest cavities made in dead trees or dead portions of live trees. Pure white, moderately glossy eggs are ovate to elliptical-ovate or rounded-ovate. Clutch size ranges 4 to 7 eggs (Walters et al. 2002). Near Fortine, egg dates are May 26 to June 3; young in nest from June 18 to July 11. Statewide, nests in June and early July (Davis 1961).
