Field Identification

53–61 cm; male 1531–1705 g (longicauda), female 1360 g (jobiensis) (1). Perhaps some overlap with T. fuscirostris, or they may replace each other altitudinally (latter lower); head of present species has curassow-like appearance, quite unlike that of T. fuscirostris or T. cuvieri (1). Dark reddish tinge on bare skin of face and neck; legs and feet orange to bright red (1); reddish-brown collar; iris brown to red (1); bill yellow-brown to dull red (1). Immature is much like adult, but has better feathered head and neck, and body plumage is browner and duller than that of adult (1). Race longicauda slightly larger.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Two subspecies recognized.

Subspecies

Exact limits of range uncertain in many areas. Several records of Talegalla in CE New Guinea; identity uncertain, but may well refer to present species.

SUBSPECIES

Talegalla jobiensis jobiensis Scientific name definitions

Distribution

Yapen I; NC New Guinea.

SUBSPECIES

Talegalla jobiensis longicaudus Scientific name definitions

Distribution

E New Guinea (W to Sepik R and possibly Aroa R).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Forested zones from sea level perhaps up to 1980 m (1) though only certainly recorded to 1390 m (2); seems to prefer dry ground, and tends to avoid areas of swamp forest; in higher parts of range, often found in ravines. In area of R Aroa (SE New Guinea) assumed to occur at higher altitudes than T. fuscirostris. Roost recorded c. 8 m up in large forest tree; copious droppings on ground below.

Movement

No information available. Presumably sedentary.

Diet and Foraging

No information available, though considered to be probably omnivorous (1).

Sounds and Vocal Behavior

Vocal day and night; generally gives series of 2–4 very loud , ascending, braying notes similar to those of T. fuscirostris but slower, fewer and of longer in duration; either “owagh-aagh” (c. 2 seconds) or “agggh-owagh-aggh-ah” (6·5 seconds) (1).

Breeding

Female in breeding condition collected in Sept in NC New Guinea, several week-old chick collected Jul (Tor R) (1), and activity around mounds witnessed Oct–Mar (1), but local people claim eggs can be found in any month (1). Mound builder; also said to be parasitic. Probably monogamous (1). Mound flat and wide, sited between large trees; alternatively, very large heap of humus measuring 90–450 cm wide × 150 cm high (1); mound temperature c. 32°–36°C; one mound was used by same pair for 3–5 years (1). Usually used by pair, once by three birds. Up to 17 eggs found in single mound (1). Said to parasitize mounds of Megapodius decollatus in NC New Guinea, but inverse seems far more likely, and probably recorded in SC New Guinea; will renovate mounds previously used by Aepypodius arfakianus (3). Much predation of eggs by monitor lizards (Varanus). Eggs vinaceous russet to brown, though outer layer flakes off during incubation (1). Chick is largely fuscous-brown above with sooty patch around eye and rusty-cinnamon underparts (1); weighs 110–125 g at hatching (1), 292 g at six weeks old.

Not globally threatened (Least Concern). Mace Lande: Safe. Total population was thought to number 10,000–1,000,000 individuals, but declining and more recently estimated at 670–67,000 birds by BirdLife. Regularly encountered in suitable habitat; common and widespread in Irian Jaya (W New Guinea), e.g. around Humboldt Bay (1). Main threats are conversion and degradation of habitat; some protected areas should be designated; suffers from intensive egg collecting, and casual hunting of adults (skins may be used to make drums) (4), but species thought to be secure in areas where human population is sparse. In Papua New Guinea, wherever human population sizeable, species rapidly exterminated by hunters. Legally protected in Indonesia.
