Citation | BirdLife International 2016. Pernis ptilorhynchus. The IUCN Red List of Threatened Species 2016: e.T22694995A93483912. http://dx.doi.org/10.2305/IUCN.UK.2016-3.RLTS.T22694995A93483912.en. Downloaded on 30 September 2019. | Description | JUSTIFICATION This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over 10 years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in 10 years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. DESCRIPTION The global population is estimated to number c.100,000-1,000,000 individuals (Ferguson-Lees et al. 2001), while national population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; < c.100 breeding pairs, c.1,000-10,000 individuals on migration and c.50-1,000 wintering individuals in Taiwan; c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Korea; c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Japan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009). Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats. HABITAT AND ECOLOGY Behaviour Birds in the northern part of its range are migratory, arriving at breeding grounds in April and May and leaving again between August and October. Further south the species is sedentary (del Hoyo et al. 1994). It migrates by flapping as well as soaring, enabling it to cross expanses of water. Small groups generally form on migration, but otherwise the species is generally seen singly or in pairs (Ferguson-Lees and Christie 2001). Habitat It inhabits woodland of various climatic types, preferring broad-leaved forests; it is recorded up to 1,800 m (del Hoyo et al. 1994). Diet Bees and wasps (usually larvae) form the main part of its diet (del Hoyo et al. 1994). Breeding site The nest is built in the fork of a tree (del Hoyo et al. 1994). Management information The species requires forest, although not necessarily old growth: it has been recorded to move back into irrigated forest plantations in Pakistan (del Hoyo et al. 1994). THREATS It is very highly vulnerable to the effects of potential wind energy development (Strix 2012). |
