Field Identification

30–35 cm. Large woodcock with shortish, rounded wings; upperparts blackish with red-brown markings; underparts almost unbarred ochre-buff. Pattern somewhat similar to that of Eurasian Woodcock (Scolopax rusticola) and Amami Woodcock (Scolopax mira), but darker above, with much brighter, almost unbarred underparts; bill and tarsi longer and much darker. Sex and seasonal differences and juvenile undescribed. Subspecies heinrichi differs in having clearly shorter bill (ca. 10%) (1).

Systematics History

Closely related to Moluccan Woodcock (Scolopax rochussenii), with which this species is sometimes considered conspecific (2, 3). Some authorities, e.g., White and Bruce (4), have preferred to consider Sulawesi Woodcock as monotypic.

Geographic Variation

Apparently solely in size (bill length).

Subspecies

Two subspecies recognized.

Systematics History

Scolopax celebensis heinrichi Stresemann, 1932, Ornithologische Monatsberichte 40:115.—Mahavu Volcano, 1,100 m, Minahassa, near Rurukan, Celebes [Sulawesi].

The holotype, a male collected on 10 February 1931 by Gerd Hermann Heinrich ( 1896–1984), is held at the American Museum of Natural History, New York (AMNH 298459) (5).

Distribution

Mountains of northeastern Sulawesi.

Identification Summary

Subspecies heinrichi based on somewhat smaller bill (ca. 10%) of just three specimens, but is nonetheless considered diagnosable (1).

Systematics History

Scolopax celebensis Riley, 1921, Proceedings of the Biological Society of Washington 34:55.—Rano Rano, Celebes [Sulawesi].

The holotype, an adult male collected on 22 December 1917 by Henry (Harry) Cushier Raven (1889–1944), is held at the National Museum of Natural History, Smithsonian Institution, Washington, DC (USNM 226174) (6).

Distribution

Mountains of central Sulawesi.

Identification Summary

Described under Field Identification.

Hybridization

Never recorded.

Fossil History

Nothing known.

Distribution

Northeastern and central Sulawesi.

Habitat

Dense, mature and relatively undisturbed montane forest at 1,100–2,500 m; hides in thick undergrowth, running when disturbed; requires some wet, open patches with little undergrowth for foraging. Several recent observations have been along streambeds, although it has been suggested that the species prefers bamboo forest in some areas (7).

Movement

Apparently sedentary.

Diet and Foraging

Feeds in wet spots; has been seen in puddles of water in hollows made by wild pigs.

Sounds and Vocal Behavior

Makes short flights over treetops at dusk, but vocalizations are unknown (1).

Breeding

Information needed.

Not globally threatened. Currently considered Near Threatened. Very poorly known with few recent records; no precise information available; inconspicuous so infrequently recorded. Known from Lore Lindu National Park in central Sulawesi (7). Ironically, small-scale collection of rattan might provide suitable breaks in dense undergrowth preferred by this species for foraging (7).
