ABSTRACT The red feathers of Pesquet’s Parrot (Psittrichas fulgidus) are highly sought after for use in the headdresses of the highland cultures of Papuan New Guinea, however, it is unclear whether the harvest for headdresses represents a serious threat to the species’ survival. To quantify the potential impact of harvesting, we surveyed 170 people in Mingende of Kerowagi District, Chimbu Province, a locality well known for their use of Pesquet’s Parrot feathers. Of the survey respondents, 43% had headdresses containing Pesquet’s Parrot feathers, owning an average of 2.9 headdresses (± 2.4 SD, N = 69) with each contained 2.9 (± 1.9 SD, N = 35) Pesquet’s Parrots. We estimated that an average of 8.4 Pesquet’s Parrots are contained within each owner’s headdresses. Extrapolating for the adult population of Kerowagi District, via a bootstrap methodology, suggested that between ~160,000 ‒ 280,000 Pesquet’s Parrots may have been harvested for the headdresses present in this district alone. Our survey results suggest an annual purchase rate of 1.5% which equates to approximately 3,200 Pesquet’s Parrots being required annually for Kerowagi District alone. This is equivalent to ~8% of the estimated wild population. Given that the extant population is widely dispersed and highly mobile across areas of remote foothill forest, in situ conservation management is unlikely to be economically viable. However, given that a greater number of Pesquet’s Parrot exist in headdresses than are alive in the wild, we suggest that the most practical conservation intervention is to focus on prolonging the lifespan of existing headdresses.

死的比活的多:仪式头饰的收获威胁到巴布亚新几内亚的佩斯凯鹦鹉

摘要 Pesquet's Parrot (Psittrichas fulgidus) 的红色羽毛在巴布亚新几内亚高原文化的头饰中备受追捧,然而,目前尚不清楚头饰的收获是否对该物种的生存构成严重威胁。为了量化采伐的潜在影响,我们对钦布省 Kerowagi 区明根德的 170 人进行了调查,该地区以使用 Pesquet 鹦鹉羽毛而闻名。在调查受访者中,43% 的头饰含有 Pesquet's Parrot 羽毛,平均拥有 2.9 个头饰 (± 2.4 SD, N = 69),每个头饰包含 2.9 (± 1.9 SD, N = 35) Pesquet's Parrots。我们估计每个主人的头饰中平均包含 8.4 只 Pesquet's Parrots。对 Kerowagi 区的成年人口进行推断,通过引导方法,表明仅该地区存在的头饰就可能收获了约 160,000 至 280,000 只 Pesquet's Parrots。我们的调查结果表明,每年购买率为 1.5%,这相当于仅 Kerowagi 区每年就需要大约 3,200 只 Pesquet's Parrots。这相当于估计野生种群的 8%。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比野外存活的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。000 Pesquet's Parrots 可能仅用于该地区的头饰。我们的调查结果表明,每年购买率为 1.5%,这相当于仅 Kerowagi 区每年就需要大约 3,200 只 Pesquet's Parrots。这相当于估计野生种群的 8%。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比野外存活的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。000 Pesquet's Parrots 可能仅用于该地区的头饰。我们的调查结果表明,每年购买率为 1.5%,这相当于仅 Kerowagi 区每年就需要大约 3,200 只 Pesquet's Parrots。这相当于估计野生种群的 8%。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比野外存活的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。我们的调查结果表明,每年购买率为 1.5%,这相当于仅 Kerowagi 区每年就需要大约 3,200 只 Pesquet's Parrots。这相当于估计野生种群的 8%。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比野外存活的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。我们的调查结果表明,每年购买率为 1.5%,这相当于仅 Kerowagi 区每年就需要大约 3,200 只 Pesquet's Parrots。这相当于估计野生种群的 8%。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比在野外生存的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比在野外生存的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。鉴于现存种群广泛分散且在偏远山麓森林地区流动性很强,就地保护管理不太可能在经济上可行。然而,鉴于头饰中存在的 Pesquet's Parrot 的数量比野外存活的要多,我们建议最实用的保护干预措施是专注于延长现有头饰的寿命。
