BirdLife species factsheet for Sao Tome Short-tail Sao Tome Short-tail Amaurocichla bocagei is restricted to São Tomé, São Tomé e Príncipe, where it occurs in the central and southern parts of the island. Known from only six records prior to 1928, it was rediscovered in 1990, in the valleys of the Xufexufe and Ana Chaves rivers (4.1-6.3 pairs and 5.6 pairs per 1 km of river, respectively) (Atkinson et al. 1991). In 1997, it was reported to be seen and heard in almost every forested river basin in the Agua Ribeira near Formoso Grande and around São Miguel (S. d’Assis Lima in litt. 1997). It is currently listed as Vulnerable under criterion D1 because it was thought to have a small population, estimated at 250-999 mature individuals (based on an assessment of known records, descriptions of abundance and range size), given the limited area of suitable habitat believed to be available to it. The overall population is thought to be stable, although it is reported that the species has deserted areas of habitat near Bombaim (F. Olmos in litt. 2007), perhaps indicating a local decline. It was once thought to be restricted to forest below 600 m (Jones and Tye 2006) and associated with water (Atkinson et al. 1991), but it has since been found to occur at over 1,000 m in the headwaters of the Ana Chaves river (F. Olmos in litt. 2007), to be fairly common in some montane forests above 1,300 m (Maia and Alberto 2009, Olmos and Turshak 2010) and show no association with water in either low elevation or montane forest (Olmos and Turshak 2010). The species appears to be more widespread than previously thought, necessitating an upwards revision of its population estimate. If the population is now estimated to number >1,000 mature individuals, the Sao Tome Short-tail would qualify for downlisting to Near Threatened (if it approaches the population threshold for Vulnerable) or Least Concern on the IUCN Red List. Information is requested on the population size and distribution of this species, and comments on the proposed downlisting are welcome. References: Atkinson, P., Peet, N. and Alexander, J.
