This information on »S. ruficollis supplements that of Parker et al. (1985) from Cruz Blanca in Piura Department, Peru. S. ruficollis is threatened by deforestation and especially the trampling of undergrowth by cattle and clearance of bamboo for pack animal fodder (Best & Clarke 1991, Parker et al. 1985). Its distribution is more montane than most of the Tumbesian endemics and it occurs in the same threatened forest types as the Grey-headed Antbird Myrmecizagriseiceps. HENNA-HOODED FOLIAGE-GLEANER Hylocryptus erythrocephalus T, indeterminate This distinctive furnariid occurred at four sites in Loja Province, Ecuador, from 600—1800 m. The 1800 m sightings at Sozoranga make that site the highest so far discovered for the species, which was pre- viously known only to 1390 m near Alamor (Chapman 1926). At Tambo Negro it was fairly common and easily located during January—March 1991, although it had not been found in August-September 1989, suggesting that it may undertake local seasonal movements. It occurred singly, in presumed pairs or in mixed-species flocks under Ceiba- dominated Deciduous Forest and Semi-evergreen Lower Montane Cloud Forest, and appeared to favour areas with a dense understorey and a thick covering of leaf-litter, often under less disturbed forest. Individuals spent much of the time on or within 1 m of the forest-floor, habitually rummaging noisily in the leaf-litter, tossing leaves and twigs into the
