The Key to Scientific Names
Legend Overview
Field Identification
46–51 cm; male 743 g, female 834 g (n = 1 for each sex) (1). Head tawny, with indistinct facial disc and no ear tufts; upperparts dark rufous and unbarred (aside from flight feathers), with creamy-buff and whitish markings on scapulars and mantle (2); face and underparts light cinnamon , with narrow rufous streaks on breast; remiges and rectrices tawny-rufous with narrow dark bars; tarsus and toes unfeathered; eyes large, contrasting strongly with pale face (3); irides dark brown (sometimes erroneously stated to be yellow); bill bluish-grey (2); cere, legs and feet yellowish (2). Differs from S. peli in much smaller size, unbarred upperparts and lack of chevron pattern below; differs from narrowly sympatric and similarly sized S. bouvieri in lacking vermiculations on upperparts and being less heavily streaked on underparts. Juvenile similar to but slightly paler than adult, probably attains adult plumage c. 6 months after fledging.
Systematics History
Subspecies
Distribution
Sierra Leone, Liberia, Ivory Coast and Ghana; possibly also Guinea.
Habitat
Endemic to Upper Guinea Forest. River and lagoon edges in lowland forest, mainly primary but also secondary forest and degraded habitat, and sometimes plantations and near villages (2); also recorded in coastal mangroves. Evidence that present species prefers smaller streams than those favoured by S. peli (4, 2).
Movement
Diet and Foraging
Little known; catfish found in 1 stomach. Presumably hunts mostly at night, but occasionally active during day (photographed at mid-day on perch above stream and on ground at stream edge (5) ).
Sounds and Vocal Behavior
Deep, dove-like “ooo” , repeated at 1-minute intervals. Call similar to that of White-crested Tiger-heron (Tigriornis leucolopha) and indeed has been confused with it in the wild (6). In one study in Ivory Coast, response to playback best during a full moon in the rainy season (7).
Breeding
Very little known. Nestlings collected in Sierra Leone suggest only 1 young raised from egg laid Sept–Oct; in Liberia, juvenile still with downy plumage in Mar, immature with mostly adult plumage in Jul; in Sierra Leone, immature roosting with adult in mid-Feb (2). Biology probably similar to that of S. peli.
Conservation Status
VULNERABLE. Formerly listed as Endangered but now known to be more widespread than previously thought. CITES II. Restricted-range species: present in Upper Guinea Forests EBA. Only 17–20 records from 1870 to 1983; BirdLife International places rough global population estimate at 2500–10,000 individuals. Reported as fairly common in Sierra Leone (Loma Mts) in 1992; thought not uncommon in Liberia in 1990s; very few records from Ivory Coast (perhaps owing to confusion over voice); only c. 5 records from Ghana; and single record from Guinea. Small number of observations suggests that species is rare, although it may be overlooked because of its elusive nature. Main threats are clearance of mangrove and forest, and river pollution; iron-ore mining has caused severe pollution to R Mano between Sierra Leone and Liberia, and R Yah in Liberia; in addition, young are captured and kept as pets by local inhabitants, and some bird are caught and eaten (8). Occurs in a few protected areas through its range, including Gola Forest Reserve (Sierra Leone), Sapo National Park (Liberia) and Tai Forest National Park (Ivory Coast). Survey and monitoring of existing population required.
