It is endemic to Taiwan.[3] TaxonomyThe Taiwan whistling thrush was collected by Robert Swinhoe and described as Myiophoneus insularis by John Gould in 1862.[4] Swinhoe called it the "Formosan cavern-bird" because it inhabits the dark, forested ravines in the mountains.[5] It was formerly considered a subspecies of the Malabar whistling thrush (Myophonus horsfieldii). The species is monotypic.[6] Distribution and habitatThis thrush is endemic to Taiwan. Its natural habitat is subtropical or tropical moist montane forests.[1] It is found at elevations of up to {{convert|2700|m|abbr=on}}.[8] DescriptionIts length is {{convert|28|to|30|cm|abbr=on}}. The wings are {{convert|15|to|16|cm|abbr=on}} long. It is mostly blackish-blue. Some feathers are navy blue or metallic blue. Some underwing coverts have white bases. The underparts are blackish.[9] Its neck, breast and flanks are scaled. Its eyes are deep red, and its lores, bill and legs are black.[7] The two sexes are alike. The juvenile is dull blackish, with a bluish tinge. The gape of the juvenile is yellowish.[8] Behaviour and ecologyActivity is greatest at dawn and dusk. It jumps among rocks in forest streams. It often opens and closes its tail when it is sitting on a rock.[8] Its call is a sharp whistle, described as screee.[8] Its song is loud and melodious whistles.[7] BreedingThe Taiwan whistling thrush is monogamous. The breeding season is from late March to early September. There are two broods each breeding season.[6] Nests are usually built in holes in rocks or trees.[8] Nests are also built in human structures.[7] They are made of twigs, roots, stems and moss. There are 2 to 4 eggs in a clutch. The eggs are pinkish with brownish or greyish marks.[8] The female incubates the eggs.[6] Incubation takes about 12 to 14 days.[8] Newly hatched chicks are altricial. They have few feathers.[6] Both parents feed the nestlings.[8] Chicks leave the nest after about 21 days.[6] DietThe diet consists of shrimp, earthworms, insects, frogs, reptiles, and fish,[8] obtained by foraging in or near streams.[7] StatusThe International Union for Conservation of Nature has assessed M. insularis to be of least concern. Its population is estimated at 10,000 to 100,000 breeding pairs and is suspected to be decreasing due to habitat destruction.[1] It was listed as other conservation-deserving wildlife in the schedule of protected species of the Taiwan Wildlife Conservation Act, but was removed from the list in 2008.[6] References1. ^1 2 {{cite journal | author = BirdLife International | title = Myophonus insularis | journal = IUCN Red List of Threatened Species | volume= 2016 | page = e.T22708334A94156924 | publisher = IUCN | year = 2016 | url = http://www.iucnredlist.org/details/22708334/0 | doi = 10.2305/IUCN.UK.2016-3.RLTS.T22708334A94156924.en | accessdate = 19 December 2016}} {{Taxonbar|from=Q386368}}{{DEFAULTSORT:thrish, whistling, Taiwan}}2. ^{{cite web|url=http://taibnet.sinica.edu.tw/eng/taibnet_species_detail.php?name_code=404613|title=Myophonus insularis Gould, 1863|website=Catalogue of Life in Taiwan|accessdate=14 September 2016}} 3. ^{{cite web|editor1=Frank Gill|editor2=David Donsker|title=Chats, Old World flycatchers|url=http://www.worldbirdnames.org/bow/chats/|website=IOC World Bird List Version 6.3|accessdate=7 October 2016}} 4. ^{{cite journal|last=Gould|first=John|date=1862|title=Descriptions of Sixteen New Species of Birds from the Island of Formosa, collected by Robert Swinhoe, Esq., Her Majesty's Vice-Consul at Formosa|url=https://www.biodiversitylibrary.org/page/28627262|journal=Proceedings of the Zoological Society of London|volume=1862|page=280}} 5. ^{{cite journal|last1=Swinhoe|first1=Robert|title=The Ornithology of Formosa, or Taiwan|journal=Ibis|date=July 1863|volume=5|issue=3|page=279|publisher=British Ornithologists' Union|doi=10.1111/j.1474-919X.1863.tb05732.x|url=https://www.biodiversitylibrary.org/page/8611315}} 6. ^1 2 3 4 5 {{cite web|url=http://eol.taibif.tw/pages/73498|title=Myophonus insularis Gould, 1863|website=Taiwan Encyclopedia of Life|accessdate=13 September 2016|language=Chinese}} 7. ^1 2 3 4 {{cite book|last=Brazil|first=Mark|date=2009|title=Birds of East Asia|url=https://books.google.com/books?id=Wk_CAwAAQBAJ&pg=PA398|publisher=A&C Black|page=398|isbn=978-0-6911-3926-5}} 8. ^1 2 3 4 5 6 7 8 {{cite book|last=Clement|first=Peter|last2=Hathway|first2=Ren|date=2010|title=Thrushes|url=https://books.google.com/books?id=IxBwBXK5HX0C&pg=PA218|publisher=A&C Black|pages=218–219|isbn=978-1-4081-3542-6}} 6 : Myophonus|Birds of Taiwan|Endemic birds of Taiwan|Birds described in 1862|Taxa named by John Gould|Taxonomy articles created by Polbot |
