Meet Indonesia’s new honeyeater species from Rote Island

first_imgA new bird species from Indonesia has been described by a group of scientists after it was first observed in 1990, a paper said.The bird, which belongs to the honeyeater family, has been named after Indonesia’s first lady, Iriana Joko Widodo, as a way to promote the protection of the species.The researchers said the newly described species’ population was primarily threatened by deforestation to clear land for residential and agricultural use. Scientists have described a new species of bird found only on the island of Rote in eastern Indonesia — but already the population of the honey-eating fowl is threatened by habitat loss as a result of rapid deforestation.The discovery of Myzomela irianawidodoae — named after Indonesia’s first lady, Iriana Joko Widodo — involved a series of separate field studies between 1990 and 2015 by different groups of researchers, according to a paper published Dec. 31, 2017, in the scientific journal Treubia.The first observation of a Myzomela species on Rote in East Nusa Tenggara province — one of the many islands that comprise the Lesser Sunda Islands — was carried out by the Australian ornithologist Ron Johnstone in 1990.Scientists have discovered a new bird species that lives only on Rote Island in eastern Indonesia.

Meanwhile, playback experiments on both Sumba and Rote triggered strong territorial reactions when recordings of the territorial song of  a male myzomela from the same island (playback of Rote recordings on Rote; playback of Sumba recordings on Sumba) were used.“The territorial song of Myzomelas has a strong biological function. Those reactions are a strong indicator that the Myzomelas from Sumba and Rote are indeed different species,” the researchers said in a statement.The final confirmation of a new bird species was made by scientists from the National University of Singapore and the Indonesian Institute of Sciences (LIPI) who went to Rote in December 2015 to capture four specimens of the bird.The team made another bioacoustic analysis, and also compared the animals’ body structure with other species in the Myzomela genus, such as the Buru myzomela (Myzomela wakoloensis), the Seram myzomela (Myzomela elisabethae), the Banda myzomela (Myzomela boiei), the Sulawesi myzomela (Myzomela chloroptera), the Sumba myzomela (Myzomela dammermani), the Timor myzomela (Myzomela vulnerata), and the red-headed myzomela (Myzomela erythrocephala).“The Rote Myzomela is closely related to other species of honeyeater that occur on surrounding Indonesian islands, but it has a unique song which differentiates it from all its relatives,” the statement said. They also noted several subtle and previously overlooked differences in shape and plumage, including a narrower black breast band than the Sumba birds.The honeyeater, Rote myzomela (Myzomela irianawidodoae), was named after Indonesia’s current First Lady Iriana Joko Widodo, as a way to promote the protection of the species which is threatened primarily by habitat loss due to deforestation.

However, they also noted that most of the island, which is only 1,226 square kilometers (473 square miles) in size, smaller than Phoenix, Arizona, had been heavily deforested and developed for residential and agricultural use to accommodate a growing population.“[Rote] does not have a major terrestrial protected area despite the fact that it has several endemic bird species as well as other birds with a highly restricted range — only shared with Timor and Semau [islands] for example — and certain species that are highly threatened throughout their range, such as the olive-shouldered parrot, the yellow-crested cockatoo and the Timor green pigeon,” Verbelen said.In Indonesia, members of the genus Myzomela, including the Rote myzomela, are protected under the country’s 1990 conservation law and a 1999 government regulation on wildlife. The researchers hope that naming the new species after the wife of President Joko Widodo will do even more to promote the protection of the bird.“The fact that this bird was named after Indonesia’s first lady generated big media attention. I believe and hope this can help the general cause of forest conservation and biodiversity protection in Indonesia. It is badly needed considering the rates of forest destruction in Indonesia,” Verbelen said.Due to these threats, the team has also suggested that the species be categorized by the IUCN as “Vulnerable,” and that follow-up surveys be made to describe the population size of the Rote myzomela.“If the Rote myzomela were to vanish from Rote, I’d expect that other unique bird species such as the Rote boobook that strongly depends on good quality forests and big trees would go extinct, too,” Verbelen said.“The world becomes a poorer place each time we are losing a species. In general, it is important to halt biodiversity loss and prevent any species from going extinct,” he added.FEEDBACK: Use this form to send a message to the author of this post.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredlast_img
