    Abstract The yellow-shouldered parrot (Amazona barbadensis) is listed in Venezuela as Endangered and internationally as Vulnerable, primarily due to poaching for the illegal pet trade. Various interventions have been implemented to reduce poaching (increasing the population from 700 in 1989 to 1600 in 2009), but poaching pressure is still high, and is ever-changing, requiring an evolving response. Between 2000 and 2003, our only intervention was environmental education in schools: in the short term, unsurprisingly, it had no impact on poaching, which reached 100% of nestlings in monitored nests. From 2004 onwards, we implemented a set of new field interventions. In 2004, 24h field surveillance decreased poaching to 56%. In 2005, the addition of foster nests and a pilot test of “assisted breeding” brought the figure down to 18%. In 2006, assisted breeding was expanded, achieving 0% poaching. In 2007, poachers raided our “secure” site, and took 34 nestlings, bringing poaching up to 60%. A pilot study of artificial nests offered promising results. In 2008 and 2009, the addition of patrolling by local police reduced poaching to 16% and 1%, respectively. During 2004-2009, nestling poaching averaged 25%. Ensuring parrot recruitment in the future will require a combination of the strategies employed to date; in the short term, expanding the use of artificial nests to increase availability of nesting sites in easily-patrolled areas has the most potential to build on past successes.

    Abstract Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of mortality due to nest poaching in 23 studies of Neotropical parrots, representing 4024 nesting attempts in 21 species and 14 countries. We also examined how poaching rates vary with geographic region, presence of active protection programs, conservation status and economic value of a species, and passage of the U.S. Wild Bird Conservation Act. The average poaching rate across all studies was 30% of all nests observed. Thirteen studies reported poaching rates of >=20%, and four reported rates openface> 70%. Only six studies documented no nest poaching. Of these, four were conducted on islands in the Caribbean region, which had significantly lower poaching rates than the mainland Neotropics. The other two studies that showed no poaching were conducted on the two species with the lowest economic value in our sample ( U.S. retail price). In four studies that allowed direct comparison between poaching at sites with active nest protection versus that at unprotected sites, poaching rates were significantly lower at protected sites, suggesting that active protection efforts can be effective in reducing nest poaching. In those studies conducted both before and after the passage of the U.S. Wild Bird Conservation Act, poaching rates were found to be significantly lower following its enactment than in the period before. This result supports the hypothesis that the legal and illegal parrot trades are positively related, rather than inversely related as has been suggested by avicultural interests. Overall, our study indicates that poaching of parrot nestlings for economic gain is a widespread and biologically significant source of nest mortality in Neotropical parrots.
