On Historical Records of Turdus Pallidus and Turdus Obscurus (Aves: Turdidae) from the Czech Republic Sylvia 46 / 2010 On historical records of Turdus pallidus and Turdus obscurus (aves: turdidae) from the czech republic O historických nálezech drozdů turdus pallidus a turdus obscurus (Aves: Turdidae) v České republice Jiří Mlíkovský Department of Zoology, National Museum, Václavské náměstí 68, CZ­115 79 Praha 1; e­mail: [email protected] Mlíkovský J. 2010: On historical records of Turdus pallidus and Turdus obscurus (Aves: Turdidae) from the Czech Republic. Sylvia 46: 149–156. Five 19th­century records of Turdus pallidus and Turdus obscurus from the Czech Republic were reported in literature. My revision of the published data, archival documents and museum specimens showed that only two specimens reported by Palliardi (1852), i.e. those collected by Wenzel Koch at Ehmet in westernmost Bohemia, probably during 1845–1851, can be accepted as probable records of Turdus obscurus. All other records (Amerling 1852, Pražák 1893) are invalid for various reasons. V literatuře je citováno pět historických nálezů drozdů Turdus pallidus a Turdus obscurus z České republiky, všechny z 19. století. Revize publikovaných údajů, archivních dokumentů a muzejních exemplářů ukázala, že za pravděpodobný historický doklad druhu Turdus obscurus z České Republiky lze považovat pouze dva jedince zaznamenané Palliardim (1852), tedy jedince ulove- né Wenzelem Kochem u vsi Ehmet v západních Čechách, pravděpodobně v letech 1845–1851. Ani jeden se však nezachoval a jejich určení nelze ověřit. Oba drozdi zmínění Amerlingem (1852) jako Turdus pallidus jsou dodnes uloženi ve sbírkách Národního muzea v Praze. Jeden je Turdus obscurus neznámého geografického původu, zatímco druhý je hypochromatický Turdus philo­ melos. Pražák (1893) si svůj údajný nález T. obscurus zřejmě vymyslel.

Koch was in a close contact Count Boguslaw Radziwill (1809–1873) with Christoph Fellner von Feldegg in Berlin. After Boguslaw’s death, his (1779–1845), an Austrian soldier and son Ferdinand (1834–1926) moved significant collector of birds, then based the collection to his manor at Antonin at Cheb (formerly Eger). The fact that (Schalow 1919: 452–453), then in Prussia, Koch did not give or sell such a rarity to now in the Greater Poland Province, Feldegg (see below for his collection) Poland (51.52°N, 17.85°E). Hammling indicates that he collected the birds after (1917: 399) found the collection there in Feldegg’s death in 1845. Both Koch’s a bad state on 6 July 1914. I am not aware specimens were thus probably collected of any specimen from this collection that during 1845–1851. Note that Palliardi (in would have survived. Anonymous 1842: 259) did not list this species among the birds of the Karlovy amerling 1852 Vary region and that Radziwill obtained Karel Slavoj Amerling (1807–1884), his specimen from Koch prior to 13 June a physician and naturalist in Praha 1851 (see Baldamus 1852: 6).

Palliardi (1852), Amerling (1852) saw in the museum were who knew the Feldegg Collection, did probably two pale­colored thrushes, not list this specimen among Bohemian possessed by the Bohemian Museum records. There is thus no evidence that (now: National Museum; hereafter the specimen originated from Europe, ‘NMP’) in the early 1850s (Frič 1854: 21). and its Bohemian origin is improbable. Both are still present in the NMP. The specimen NMP P6V­001629 is The specimen NMP P6V­001152 is a leucistic Turdus philomelos Brehm, 1831 Turdus obscurus (Frič 1854: 21, 1866: (Frič 1854: 21, 1866: No. 686).

Feldegg (1779–1845). This agrees with an entry in the catalogue of the Feldegg Pražák 1893 Collection (Feldegg 1842). Note that Josef Prokop Pražák (1870–1904), Amerling (1851) did not know about a zoologist and journalist from the bird, while he mentioned it one year Hořiněves in Eastern Bohemia, allegedly later (Amerling 1852), which coincides collected “Turdus obscurus” in autumn with the acquisition by NMP of bird 1892 at “Přim unweit Königgrätz” [= specimens from the Feldegg Collection Přím, Eastern Bohemia; 50.17°N, (Frič 1853, Štěpánek 1975).

Pražák was reported that the bird originated from a notorious swindler, whose faunistic Bohemia (adding an exclamation mark records are useless (Lorenz­Liburnau in parentheses) and this information 1898, Kleinschmidt 1905, Schmuck was apparently added to the bird on 2010, J.

However, Frič (1871, 1872) did probably existed only in Pražák’s mind. not mention this record in his later papers on the birds of Bohemia.

However, there is no (Naumann 1850, 1851, 1860, Finsch 1863, evidence that the specimen originated Seebohm 1879), which needs to be taken from Bohemia. Feldegg (1842) divided into account when trying to interpret his catalogue geographically into sub­ early bird records (Mlíkovský 2009). The catalogues (‘Catalogues’ in his wording) Asian species currently distinguished of European and non­European birds, as Turdus pallidus Gmelin and Turdus respectively. He listed this specimen obscurus Gmelin were considered in the “European” sub­catalogue.

By Steve Hilty One of the top highlights mentioned by most members of the group was a Ural Owl sleeping in a large, picturesque tree hollow. It was, in fact, an image that could have been plucked straight from an illustrated book of fairy tales from the Middle Ages. A male Eurasian Bullfinch in beautiful morning light also garnered top honors and, surprisingly, so did the diminutive Japanese Pygmy Woodpecker. For several of us, a large flock of Rooks eluding repeated prey- capture attempts by a Peregrine Falcon (the Rooks being more capable and wily than they might appear) over a large expanse of rice paddies was a trip highlight. Also prized were more than a dozen Stellar’s and White-tailed sea-eagles perched on a forested Hokkaido hillside during a snowstorm. The arrival of a Blakiston’s Fish-Owl at a small pool resulted in a mass exodus from our rather sedate and stylized Japanese dinner. And yes, then there were the Japanese Cranes, lumps of black and white fluff standing in a frigid river as steamy mists from the thermally- heated river water rose around them—a surreal and unforgettable setting. Surprisingly, perhaps, the Mandarin Ducks received not a single nod at the end—perhaps because they were a little distant—although they generated much excitement the morning we saw them, and the image of a stately pair cruising steadily across a mirror-smooth lake in early morning light, their narrow wake line trailing behind, will not likely be forgotten.

The impressively marked bird had been collected on the Marquesas Islands – a remote spot of the Pacific Ocean that would become part of French Polynesia. The members of the Society present at that meeting would have undoubtedly been impressed by yet another of the rare, exotic gems that Gould had a habit of pulling out of his seemingly bottomless hat. Next up in this Victorian frontiers-of-ornithology ‘show and tell’ was Hugh Edwin Strickland (1811-53). The birds he spoke about2 were quite a bit closer to home, although many were every bit as exotic as Gould’s Polynesian parrot. Strickland, instead of sourcing his specimens from the far corners of the Earth, had simply popped across London to Hyde Park Corner with his note book. There, causing quite a stir, was an exhibition of "Ten Thousand Chinese Things", displayed in a purpose-built “summer house” whose design was, according to The Illustrated London News3, “usual in the gardens of the wealthy, in the southern provinces of China”.

    The magnificent Reeves's Pheasant was one of the many specialties seen on this tour (Brendan Ryan). EASTERN CHINA 3 – 27 MAY 2017 LEADER: HANNU JÄNNES Birdquest’s Eastern China tour, an epic 25 day journey across much of eastern China, focusses on an array of rare Chinese endemics and migrants, and this year’s tour once again proved a great success. The focus of the first part of the tour is to achieve good views of rarities like Spoon-billed Sandpiper, the critically endangered Blue-crowned (Courtois’s) Laughingthrush, the superb Cabot’s Tragopan and Elliot’s Pheasant and the ultra-rare Chinese Crested Tern. This was successfully achieved alongside a plethora of other much sought after species including White-faced Plover, Great Knot, stunning Saunders’s Gulls, Reed Parrotbill, eastern migrants, including Pechora Pipit, Japanese Robin, Japanese Paradise, Yellow-rumped, Narcissus and Mugimaki Flycatchers, and forest species like Brown-chested Jungle Flycatcher, White-necklaced Partridge, Silver Pheasant, Buffy and Moustached Laughingthrushes, Short-tailed Parrotbill, Fork-tailed Sunbird and the delightful Pied Falconet. Quite a haul! 1 BirdQuest Tour Report: Eastern China 2017 www.birdquest-tours.com Crested Ibis at Dongzhai Nature Reserve (Brendan Ryan). The second part of the tour, the ‘Northeast Extension’, visited a series of sites for various other Chinese specialities. Beginning in Wuhan, we bagged the amazing Reeves’s Pheasant and Crested Ibis, as well as stunners that included Fairy Pitta and Chestnut-winged Cuckoo. We then moved on to Jiaocheng for the fabulous Brown Eared Pheasants before flying on to Beijing, where the mountains of the nearby Hebei province yielded the endemic Chinese Beautiful Rosefinch, Chinese Nuthatch, Green-backed and Zappey’s Flycatchers and the rare Grey-sided Thrush.

  • An Unusual Migration of Birds at Tokyo, Japan
    AN UNUSUAL MIGRATION OF BIRDS AT TOKYO, JAPAN BY H. ELLIOTT MCCLURE EATHER has long been recognized as a contributing factor in bird mi- gration. In recent years much has been written concerning bird movements and weather in North America (Lowery, 1945; Lincoln, 1950; Williams, 1950, 1952; Gunn and Cracker, 1951, Bullis and Lincoln, 1952; Imhof, 1953; and many others). That the phenomenon of bird movement be- fore “fronts” of weather would not be confined to North America is self- evident. Undoubtedly it is variously reported in the many journals and lan- guages of Europe. Reports of such movements in Japan would be illegible to most American students unless summarized in English. Because of this, I wish to present here observations of a movement of birds before a front that swept over Tokyo on October 31 - November 1, 1953. Migration through Japan is of long duration, lasting from late July and early August with the appearance of Wandering Tattlers (Heteroscelus in- canus) and other shorebirds, which have finished nesting in the Arctic, until late December when the last thrushes have come in from Siberia and Man- churia. Because of this there is a continuous flow of birds rather than a great influx. These flights include thrushes, bramblings, bulbuls, etc., reared in the vast continental areas of Siberia and Manchuria, and those more locally produced, from Sakhalin, Hokkaido, and northern Honshu. The continental populations may cross the Japan Sea (Austin, 1947) or move down the chain of islands from Sakhalin. An unknown percentage of these populations re- mains in Honshu, Kyushu, and Shikoku for the winter, while the remainder moves on down the Ryukyu Island chain to disperse into the Philippines, Formosa, and more southern islands.

  • A Sight Record of Eyebrowed Thrush (Turdus Obscurus) in British Columbia
    A Sight Record of Eyebrowed Thrush (Turdus obscurus) in British Columbia. By Rick Toochin, Peter Hamel and Margo Hearne. Submitted: April 15, 2018. Introduction and Distribution The Eye-browed Thrush (Turdus obscurus) is a highly migratory, but secretive passerine that breeds in dark taiga in lowlands and montane forests in north-east Asia from the Kamchatka Peninsula, northern end of Sakhalin Island, on the Kuril Islands, Ussuriland, northern China, northern Mongolia, and west to central Siberia (Hamilton et al. 2007, Brazil 2009). Breeding in Japan is suspected but unproven (Brazil 1991). The Eye-browed Thrush is a common migrant throughout Japan, Korea, and Taiwan (Brazil 2009). This species winters in mature forests and evergreen forests from Taiwan, southeastern China, to Northeastern India, south through parts of Burma, into Thailand, Laos, Vietnam, Malaysia, into western parts of Indonesia, Sarawak, Philippines, and in the eastern Indian Ocean on the Andaman and Nicobar Islands (Clements 2000, Brazil 2009). In North America, the region that the Eye-browed Thrush occurs regularly is in Alaska where it is a rare spring and casual fall migrant in the Western and Central Aleutian Islands (West 2008). This species is also a casual vagrant migrant in the spring and fall at St. Paul Island, St. Matthew, and St. Lawrence Islands (West 2008). Elsewhere in the state the Eye-browed Thrush is an accidental spring migrant vagrant to Wales, Nunivak Island, and northern Alaska at Barrow (West 2008). The best places to find this species in the state are on Shemya Island or Adak Island or at Gambel in the fall (West 2008).
