This species has been uplisted to Endangered 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).

|Range Description:||Psittacus timneh, which was formerly considered conspecific with P. erithacus, is endemic to the western parts of the moist Upper Guinea forests and bordering savannas of West Africa, from Guinea-Bissau east through southern Guinea, Sierra Leone, and Liberia east to at least 70 km east of the Bandama River in Côte d'Ivoire. The species has been previsouly listed as occurring in Mali, but this appears to be erroneous (Dowsett-Lemaire and Dowsett 2005). Côte d’Ivoire and Liberia are thought to hold the largest populations (Dändliker 1992). It appears to have disappeared completely from the forests on and near Mt Nimba in Nimba County, Liberia; surveys between 2008-2011 in the East Nimba Nature Reserve and nearby forest failed to find the species, and no there was no indication from locals that they have been present in recent times (B. Phalan and F. Dowsett-Lemaire in litt. 2012). The species was surprisingly scarce in the Nimba area as early as the 1970s (Colston & Curry-Lindahl 1986). In Côte d’Ivoire there have been declines in Tai National Park and the complete disappearance of the species from some areas near human settlements (Martin et al. 2014). Gatter (1997) estimated c.1,400 birds smuggled from Côte d’Ivoire annually between 1981-1984, over 99% being P. timneh. In the Gola Forest area in Sierra Leone it persists but never seems to have been particularly abundant, with groups rarely reaching double figures (J. Lindsell and F. Dowsett-Lemaire in litt. 2012). Trapping for the wild bird trade and high rates of forest habitat loss are presumed to be driving rapid declines throughout the range.|

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. This gave a total estimate of c.120,000-259,000 individuals in 1992. However, this is likely to have been an overestimate and the population may now be lower if the species is declining rapidly (R. Martin in litt. 2016). Gatter (1997) estimated significantly higher density of two breeding pairs / km2 in logged forest north of Zwedru, Liberia, and a recent status assessment for the population in Guinea-Bissau indicates a national population of 250-1000 individuals, with very low population densities (or an absence) everywhere in that country, with the exception of small (<8km2) islands remote from permanent human habitation (Martin et al. in prep., da Costa Lopes 2014). However, 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, although it is likely to be closer to the lower bound of this range, or maybe even number fewer individuals than this (R. Martin in litt. 2016).
Trend Justification: 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). There has been a dramatic decline (of 90-99%) in the closely related and ecologically similar P. erithacus in Ghana (Dowsett-Lemaire and Dowsett. 2014, Annorbah et al. 2016) and it is likely that similar processes that led to the decline have operated and continue to operate in neighbouring countries (in the case of exploitation for the overseas pet trade possibly at even greater intensities over the last two decades) (R. Martin in litt. 2016). Additionally, there is no evidence of ‘substantial’ populations elsewhere in their range beyond Sapo NP Liberia (Freeman 2014) and Gola NP Sierra Leone (Klop et al. 2010, Dowsett- Lemaire and Dowsett 2007). 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 >50% in three generations (47 years) may be likely.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||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.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||15.5|
|Movement patterns:||Not a Migrant|
The species has been heavily traded: since 1975 reported exports are greater than 1.3 million individuals; during 1994-2003, over 359,000 wild-caught individuals (combined total of erithacus and timneh, the majority erithacus) were reportedly exported from range states; and 2005-2014 exports have been 199,070 individuals (UNEP-WCMC CITES Trade Database, October 2005, R. Martin in litt. 2016). 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 recommended 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 since then all of these countries continue to have zero export quotas recommended by CITES. Guinea-Bissau has not issued any export permits since 2000, however these restrictions have been circumvented and exports of wild-sourced birds have continued under the guise of legal trade (R. Martin in litt. 2016). For several years Guinea exported significant numbers as ‘Captive-bred’ despite there being no commercial-scale breeding facilities in Guinea (CITES 2012). Additionally, multiple shipments have been made from Mali despite the species not naturally occurring there. In late 2015, a shipment of 89 Timneh parrots that originated in Mali was confiscated in Dakar (R. Martin in litt. 2016). In addition, despite there being no legal avenues for commercial exports of wild-sourced birds, some traders continue to advertise exports of recently obtained birds (R. Martin in litt. 2016). 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), and since then exports have been re-oriented to the Middle East (R. Martin in litt. 2016). In 2009. Ghana largely ceased legal exports of P. erithacus in the early 1990s and around that time trappers and traders from Ghana also moved into other countries. As a result there was additional trapping pressure. Since Ghana ceased commercial exports, P. timneh range states (+Mali) have exported 122,868, with Cote d'Ivoire and Guinea each exporting around 46,000 (not all P. timneh as some were P. erithacus) (R. Martin in litt. 2016). 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), which is a threat to the stability of breeding populations (da Costa Lopes 2014, da Costa Lopes, in prep.). An analysis of the factors that predict the distribution and abundance of Timneh parrots on the Bijagós islands of Guinea-Bissau found that the proximity of a permanent human population had a strong negative effect on this species, suggesting human activities are a threat to populations above and beyond the impact they have on forest cover (Martin et al. in prep.)
Conservation Actions Underway
P. erithacus, prior to an acknowledgement of the split of timneh, was 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 has been the subject of several CITES significant trade reviews (Inskipp et al. 1988, R. Martin in litt. 2016), and has now been listed on CITES Appendix I (S. Chng in litt. 2016). 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. In Guinea-Bissau management of protected areas in participation with local communities has been active for several years. As part of this programme, since 2013, former parrot trappers have been employed as nest guards and in other conservation roles, which has had a positive effect on levels of nest poaching in key nesting sites and nesting trees have been protected during land clearance for shifting agriculture (Henriques and da Costa Lopes 2014). Research into breeding biology and diet in Guinea-Bissau is ongoing. Ecological surveys and community outreach has been carried out throughout the archipelago, laying the foundation for future monitoring and the expansion of community-based conservation efforts (R. Martin in litt. 2016). Martin et al. (2014) surveyed nationals of all range states including ornithologists, field researchers and conservation practitioners to establish information on research initiatives underway and the status of populations. Since that initiative surveys have been additionally conducted in Guiena-Bissau (Martin et al. in prep., da Costa Lopes 2014) and Liberia (Freeman 2014). 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
Concerns about the impact of ongoing trade on declines have led to Guinea-Bissau, together with multiple range states for P. erithacus to propose both P. timneh and P. erithacus (currently recognised as a single species by CITES) are transferred to CITES Appendix I, prohibiting international trade under CITES (R. Martin in litt. 2016). Ensure that proposed trade restrictions are implemented. Monitor wild populations to determine ongoing trends. Transfer to CITES Appendix I. Identify key sites for conservation in Guinea, Sierra Leone, Liberia and Côte d’Ivoire, and study their current distribution, abundance and possible additional threats there.
