||15-18.5 cm. A small thrush. Chestnut-brown crown to nape, russet-brown mantle, back and scapulars to uppertail-coverts, two broad white wing-bars. White chin to upper breast, blackish face, sides of throat, and rest of breast. Rest of underparts pale, washed brownish on flanks. Similar spp. None in limited range. Voice Song more like a begging call than true song, in contrast with that of Z. interpres, which is slower and less varied.

This species is listed as Near Threatened because it has an extremely small range, and its population may be both moderately small and continually declining owing to habitat loss, although it does tolerate degraded forest. Information is urgently required on the status and trends of habitat on Enganno, the intensity of trapping pressures, and this species's population size and trends. Such new information may show that it warrants listing in a threatened category.
|Previously published Red List assessments:|
- 2012 – Near Threatened (NT)
- 2008 – Near Threatened (NT)
- 2006 – Near Threatened (NT)
- 2004 – Not Recognized (NR)
- 2000 – Not Recognized (NR)

|Population:||The population is estimated to number 10,000-19,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.|
Trend Justification: Although available data are minimal, the species may be declining owing to forest loss through agricultural encroachment and hunting for the bird trade.
