Crested Honey Buzzard Pernis ptilorhynchus Status: LOWER RISK Population Trend: Unknown. Other Names: Asiatic Honey-buzzard, Common Honey-buzzard, Crested Honey- buzzard, Eastern Honey Buzzard, Eastern Honey-buzzard, Honey Kite, Oriental Honey- buzzard, Oriental Honey Buzzard. Distribution: Indomalayan/Palearctic . Breeds in two probably discrete populations, one from southern (temperate-zone) SIBERIA and northeastern CHINA south to Baikal, Amurland, Sakhalin, northern JAPAN and the Yellow Sea, and the other on the Indian subcontinent (INDIA, SRI LANKA) and southern CHINA south through the Malay Peninsula, PHILIPPINES, SUMATRA, JAVA, and BORNEO; northern breeding populations winter in INDIA, southern CHINA, southern JAPAN, MYANMAR, Malay Peninsula, INDONESIA, and the PHILIPPINES south to SULAWESI. Turkey: Vagrant (Laine 1996, Kirwan et al. 1998). Lebanon: The only records are one at Amoun on 7 October 2003 (Ramadan-Jaradi et al. 2004) and 10 reported past Bhamdoun between 27 August and 1 October 2006 (Balmer and Betton 2007). Jordan: Vagrant. A first-summer female was seen at the Aqaba sewer works on 17 April 2007 (Balmer and Betton 2007). Israel: Vagrant. Records include an adult male photographed in the Eilat Mountains on 14 May 1994 (Shirihai 1994, 1996) and six observed migrating over the Hula Lake, Northern Valleys, and Judean Desert during autumn 2007 (Balmer and Betton 2008). One wintered at Eilat through February 2008 (van den Berg and Haas 2008). Egypt: The only records are a bird recorded in May 1966 (Baha el Din and Baha el Din 1997) and another seen flying southwest over Sharm e-Sheik on 27 October 2007 (Balmer and Betton 2008). Kuwait: Scarce passage migrant (Gregory 2005). United Arab Emirates: Rare winter visitor from November to March. First recorded in November 1992, but apparently occurs annually (Richardson et al. 2003). One was seen at Hatta Dam on 13 July 2007, and up to three were recorded at Abu Dhabi city from 20 September onward (Balmer and Betton 2008). Oman: Vagrant, with single records in January, April, May, and September, and two in December (Eriksen et al. 2003). Seven were seen in West Salalah on 15 November 2007 (Balmer and Betton 2008). Yemen: Vagrant. The first record was a bird seen at Al-Kadana on 17 January 2007 (Balmer and Betton 2008). Gabon: Clark and Christy (2006) observed and photographed a bird near Tchimbélé, Monts de Crystal, on 13 August 2004, which they identified as this species. A majority of a panel of 13 experts who reviewed the photographs and text agreed that the bird was a Pernis , three thought it was an African Harrier-hawk in atypical plumage, and one thought it was a hybrid between P. ptilorhynchus and P. apivorus . If valid, this would represent the first record for sub-Saharan Africa. Russian Asia: Rare breeding species in southern Siberia, Transbaikal, Soviet Far East, and Sakhalin Island, inhabiting deciduous and coniferous forests (Flint 1984). Kazakhstan: Rare to scarce passage migrant ( orientalis ), occurring in eastern Kazakhstan, mainly in the Altai, the area south of Lake Balkhash, and the Tien Shan foothills, where the largest numbers have been observed at the Chokpak Pass (Wassink and Oreel 2007). Two juveniles were seen on 25 September 2003 at Kosmotanziya in Ili- Alatau National Park, in the Zailiyskiy Alatau at a record altitude of at least 4,500 m (Wassink and Oreel op cit.). Iran: Scarce winter visitor (Scott and Adhami 2006). Nepal: Fairly common resident and passage migrant (ruficollis) (Inskipp and Inskipp 1991). Bhutan: Frequent passage migrant in the temperate zone and foothills from 200-3,000 m and may also breed. Spring passage is from late March to late May, peaking from mid- May, and autumn passage is from late September to late November, peaking in the second half of October (Spierenburg 2005). Christmas Island: Vagrant, with a single record of a bird in December 2001 (Clarke 2003). South Korea: One of the most abundant raptors on Socheong Island, especially in autumn (Moores 2007). Hong Kong: Scarce passage migrant, mostly in autumn, with isolated winter records. Recorded in migration between 4 September to 30 October and 21 March to 20 April and in winter between 26 November to 5 February (Carey et al. 2001). Korea: One of the most numerous raptors recorded on Socheong Island (in the Yellow Sea west of the Korean Peninsula), especially in autumn, when as many as 1,240 have been recorded passing west in a single season (2005) (Moores 2007). There are also multiple records from both South Korea (Park 2002) and North Korea (Tomek 1999, Duckworth 2006). West Malaysia and Singapore: Regular and common passage migrant, less common non-breeding visitor, and presumed breeding resident (Wells 1999). Rare resident (torquatus) from low elevations up to 1,200 m, south to Johor. The race orientalis is a common passage migrant, particularly at Tanjung Tuan (Melaka), at both low and high elevations south to Singapore (Jeyarajasingam and Pearson 1999). Philippines Fairly common to common resident and migrant. The race palawanensis is endemic to Calauit and Palawan. The race philippensis is endemic to Basialn, Biliran, Catanduanes, Cebu, Leyte, Luzon, Mindanao, Mindoro, Negros, Panay, and Samar, and orientalis is a migrant, recorded from Jolo, Luzon, Mindoro, and Negros. Occurs from lowlands to middle elevations to about 1,500 m (Kennedy et al. 2000). Sumatra: Resident (torquatus) in forested areas in lowlands, but no confirmed breeding records (Van Marle and Voous 1988). Usually considered to be rare, but this is doubtful. The northern race orientalis was reported from November to February by Van Marle and Voous (op cit.), but Buij et al. (2006) recorded some birds as early as September. Their observations suggest that large numbers of this species are crossing the Straits of Malacca from Peninsular Malaysia as early as October, a month earlier than indicated by Medway and Wells (1976). Sabah: Common resident and winter migrant from sea level to 1,000 m (Sheldon et al. 2001). Thiollay (1983) regarded this species as the most common raptor at Gomantong and Kinabalu. Wallacea: Rare winter visitor (orientalis) in the Sulawesi subregion and the Lesser Sundas, but possibly also a local resident on Sumbawa and Flores, occurring from sea level to 1,200 m. Migrants occur from October to April (Coates and Bishop 1997). Australia: Vagrant, with only two records. A specimen in the Western Australian Museum was found dead near Kalgoorlie, Western Australia, in January 2003 (Anon. 2003) and a bird seen and photographed on 5 May 2005 at Waterfall Creek, Kakadu National Park, Northern Territory (Gregory 2007). Subspecies: 6 races. P. p. orientalis : Southern SIBERIA south to MANCHURIA, JAPAN, and KOREA; winters in southeastern Asia, INDONESIA, PHILIPPINES, and SULAWESI; P. p. palawanensis : PHILIPPINES (Palawan and Calauit); P. p. philippensis : Northern and eastern PHILIPPINES; P. p. ptilorhynchus : JAVA; P. p. ruficollis : INDIA and SRI LANKA east through BURMA to south-central CHINA; P. p. torquatus : Malay Peninsula, SUMATRA, and BORNEO. Some of the subspecies of P. ptilorhynchus listed here may be near the species threshold (Orta 1994). Other putative forms not accepted here include japonicus, neglectus, and gurneyi , applied to populations in Japan, Taiwan, and Burma, respectively. Taxonomy: The genus Pernis is a primitive accipitrid with no close relations to Buteo (Seibold and Helbig 1995). Wink (1995) found that it clusters with the Neophron/Gypaetus clade of Old World vultures. Based on molecular sequences of the cytochrome b gene, Gamauf and Haring (2004) found that the cuckoo hawks, Aviceda , form a sister group to Pernis , but their analysis indicated that Henicopernis and the Old World vultures, Gypaetus < and Neophron appear only distantly related to Pernis . The relationships of this form to Pernis apivorus have been much debated, and some authors (e.g., Brown and Amadon 1968) have lumped the two taxa into a single species, based partly on reports of individuals with intermediate characters from Siberia and Kazakhstan (Vaurie 1965). That possibility is disputed by some authors, and most recent authorities have continued to maintain them as separate species. Surprisingly, the molecular studies of Gamauf and Preleuthner (2005) indicated that the two species are monophyletic and do not even form a superspecies. Beaman (1994) provided well-reasoned arguments against the use of the name "Oriental Honey Buzzard" for this species, as had been proposed by Sibley and Monroe (1990), Peters (1931) recognized only a single species of Pernis ( P. apivorus ) with five subspecies. He placed the genus Pernis together with the genera Aviceda, Henicopernis, Leptodon, Chondrohierax , and Elanoides in a new subfamily, Perninae. Based on plumage development, morphological, and osteological characters (Jollie 1977) and skeletal and feather lice characters (Holdoway 1984), Pernis has been regarded as a basal lineage of the Accipitridae and clusters with the Old World vultures, Gypaetus and Neophron . De Boer and Sinoo (1984) also proposed a relationship between Pernis and Gypaetus , based on karylogical analyses. Finally, Wink (1995) and Wink and Sauer- Gürth (2000) confirmed these relationships, using molecular sequences of the mitochondrial cytochrome b gene. In contrast, based on molecular sequences of the cytochrome b gene, Gamauf and Haring (2004) found that the cuckoo hawks, Aviceda , form a sister group to Pernis , but their analysis indicated that Henicopernis
