This newly-split species is listed as Vulnerable because it is subject to heavy trapping pressure across much of its range. In combination with the high rate of ongoing habitat loss, the species is therefore suspected to be declining rapidly over three generations (47 years). Better data on the population size and extent of capture for trade may lead to its further uplisting in future.

The West African form timneh of Grey Parrot P. erithacus shows substantial morphological differences from erithacus, and the two forms have an allopatric distribution: the treatment of the two as separate species has been accepted by the BirdLife Taxonomic Working Group.
A mottled grey, medium-sized parrot. It has a large bill with a light, horn-coloured area to part of the upper mandible, and white mask enclosing a yellow eye. The tail is a dark maroon. Similar spp. P. erithacus is larger and paler grey, with a bright red tail and all-dark bill. The native ranges of the two species do not overlap, but escapes occur.
Based on the estimated density of the species and P. erithacus in Ghana and Guinea, Dändliker (1992) calculated population estimates for Côte d'Ivoire (54,000-130,000 individuals), Liberia (50,000-100,000), Sierra Leone (11,000-18,000), Guinea (5,000-10,000) and Guinea-Bissau (100-1,000). These estimates have been used as the basis for setting export quotas in the past. Assuming any population in southern Mali to be insignificant, this gives a total estimate of c.120,000-259,000 individuals in 1992, which may now be lower if the species is declining rapidly. Gatter (1997) estimated significantly higher density of two breeding pairs / km2 in logged forest north of Zwedru, Liberia, however, thus the likely total population remains highly uncertain. The population is placed in the band 100,000-499,999 mature individuals in the absence of further data.
Population declines have been noted across the range. In all of these declines, trapping for the wild bird trade has been implicated, with habitat loss also having significant impacts. Gatter (1997) estimated c.1,400 birds smuggled from Cote d’Ivoire annually between 1981-1984, over 99% being P. timneh. In 2009 Guinea exported 720 timneh, despite having a quota of zero (Anon 2011). Legal trade as monitored by CITES may represent only a proportion of the total numbers captured from the wild, while Allport (1991) estimated that c.77% of the Upper Guinea EBA forest cover had been lost at the time of that study, and regional forest loss has continued since that date at a high rate (H. Rainey in litt. 2010). The rate of decline is hard to quantify, but given the massive level of capture for trade and the high levels of forest loss in parts of the range a decline of 30-49% in three generations (47 years) may be a conservative estimate.
Although typically inhabiting dense forest, they are commonly observed at forest edges, clearings, gallery forest, mangroves, wooded savannah, cultivated areas, and even gardens (Juniper and Parr 1998), but it is not clear whether these are self-sustaining populations. May make seasonal movements out of the driest parts of the range in the dry season.
The species has been heavily traded: during 1994-2003, over 359,000 wild-caught individuals (combined total of erithacus and timneh, the majority erithacus) were reportedly exported from range states (UNEP-WCMC CITES Trade Database, October 2005). Together with P. erithacus, it is one of the most popular avian pets in Europe, the United States, and the Middle East due to its longevity and unparalleled ability to mimic human speech and other sounds. While there has been some domestic demand within range states, most impacts seem to be due to international trade, probably owing to the high value of this species. The Animals Committee of CITES imposed a two-year ban from January 2007 on exports of timneh from four West African countries (Cote d'Ivoire, Liberia, Sierra Leone and Guinea), and the importation of wild-caught birds into the EU was prohibited in 2007, leading to a fall in exports of erithacus and timneh, but the number of exportations rose once again in 2008 and 2009 (Anon 2011). In 2009 Guinea exported 720 timneh, despite having a quota of zero (Anon 2011). Legal trade as monitored by CITES may represent only a proportion of the total numbers captured from the wild. Habitat loss is undoubtedly having significant impacts throughout the range. Allport (1991) estimated that c.77% of the Upper Guinea EBA forest cover had been lost at the time of that study. Regional forest loss has continued since that date at a high rate (H. Rainey in litt. 2010). In Guinea and Guinea-Bissau, preferred species of nesting trees are also preferred timber species (Clemmons 2003).
Conservation Actions Underway
P. erithacus, prior to the split of timneh, was put on CITES Appendix II with all Psittaciformes in 1981 at the request of Switzerland and Liechtenstein. Due to concern about the effects of the large numbers of this species traded, it was the subject of a CITES significant trade review, in which it was listed as of "possible concern" (Inskipp et al. 1988). The Animals Committee of CITES imposed a two-year ban from January 2007 on exports of timneh from four West African countries (Cote d'Ivoire, Liberia, Sierra Leone and Guinea), and the importation of wild-caught birds into the EU was prohibited in 2007 (Anon 2011). In 2009 Guinea exported 720 timneh, despite having a quota of 0 (Anon 2011). Legal trade as monitored by CITES may represent only a small proportion of the total numbers captured from the wild. The species occurs in a number of protected areas. A PhD study assessing distribution, abundance and impacts of trade and habitat loss for timneh was due to begin in 2011 (Anon 2011).
Conservation Actions Proposed
Ensure that proposed trade restrictions are implemented. Monitor wild populations to determine ongoing trends.
