Justification:
Trapping for the cagebird trade and habitat loss are the most important threats to this species. Despite heavy trapping pressure in the early 1990s, the species's range is believed to have remained essentially the same, and populations have remained stable or declined less steeply than was previously feared they might, with a recent estimate even suggesting a population increase. Owing to its small breeding range and highly fragmented habitat, the species qualifies as Vulnerable.

History:
2012 Vulnerable

Geographic Range [top]

Range Description: Amazona brasiliensis occurs in a narrow littoral strip, between the Serra do Mar and coast, from Itanhaém in São Paulo through Paraná to extreme north-east Santa Catarina, south-east Brazil (Lalime 1997). Breeding areas are mostly located on small estuarine islands with few on the mainland. Populations were thought to have declined from c.3,500-4,500 birds in the 1980s to fewer than 2,000 individuals by 1991-1992 (Martuscelli and Scherer Neto 1993). A recent estimate of 6,600 individuals suggests long-term conservation measures have enabled the speccies to make a recovery (Waugh 2006). The population in Paraná was estimated at 3,600 in 1996 (Lalime 1999), and a more recent census found 3,379 birds, suggesting that the population there is either stable or has suffered a small decline (F. Olmos in litt. 2003).

Population [top]

Population: The population is estimated to number 4,000-5,500 individuals, roughly equating to 2,700-3,700 mature individuals.
Population Trend: Increasing

Habitat and Ecology [top]

Habitat and Ecology: Almost the entire population migrates daily between mangrove and littoral forest roosting and breeding areas, and Atlantic forest feeding areas. It feeds primarily below 200 m, but has been recorded up to 700 m (Lalime 1997). At the extremes, breeding occurs from late August to early March, with up to four eggs laid in natural tree-cavities, mostly in Gerivá palms Syagrus romanzoffianum and Guanandi Callophyllum brasiliense (Lalime 1997, Lalime 1999). Although essentially frugivorous, it also feeds on leaves, flowers and insects within fruit (Lalime 1997).

Systems: Terrestrial

Threats [top]

Major Threat(s): There is extensive poaching for national and (especially) international trade with 356 birds, mostly nestlings, captured during 1991-1992 breeding season in the municipality of Cananéia (a quarter of the species's range) (Martuscelli 1994). Of 47 nests monitored between 1990 and 1994, six were naturally predated and the other 41 robbed by humans (Martuscelli 1997). Nest-cavities are virtually always damaged when removing nestlings, reducing the number available (Martuscelli 1994). There is continuing habitat loss for boat building, banana plantations, cattle- and buffalo-grazing and beach houses (Lalime 1999, Snyder et al. 2000). Palmito palms are cut for processing in Guaraqueçaba (Lalime 1999). The proposed construction of a bridge to Ilha Comprida will increase pressure from tourism and habitat conversion (Snyder et al. 2000).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix I and II and protected under Brazilian law. It occurs within 15 protected areas, but these are not locally enforced (Martuscelli 1994, Lalime 1999). Superagui National Park, Paraná protects the stronghold (R. Bóçon in litt. 2006). The creation of new reserves is hampered by economic interests (Martuscelli 1994). Several programmes are raising local awareness (Martuscelli 1994, Lalime 1999, Padua et al. 2001). Conservation projects and the protected areas created in the species range seem to be paying off, although some trapping still occurs. There are studbooks and successful captive-breeding programmes in the European Union and Brazil (Lucker 1998) and the provision of artificial nests and the repair of natural nesting cavities is boosting reproductive success in the wild (Waugh 2006). The Red-tailed Amazon Conservation Project is monitoring the population in Paraná (R. Bóçon in litt. 2006).

Conservation Actions Proposed
Carry out surveys to monitor population trends and support captive breeding programmes. Monitor rates of off-take for trade. Monitor trade levels. Monitor rates of habitat loss and degradation. Enforce laws on trafficking, especially on access routes to breeding islands (Lalime 1997, Lalime 1999). Effectively protect existing reserves (Lalime 1997, Lalime 1999). Formally designate Ilha Comprida State Park and Itapanhapina Ecological Station (Snyder et al. 2000). Expand Superagüi National Park to include Ilha do Pinheiro (Snyder et al. 2000). Reforest breeding islands (Lalime 1999). Continue and expand awareness efforts (Lalime 1999).
