There Has Been A Remarkable Discovery Of 10 New Songbirds Species On Remote, Forested Indonesian Islands
Birds are fascinating for many reasons; charming appearance, beautiful singing, and gorgeous look are just some of included. Those passionate bird watchers and lovers know that about five new bird species are identified per year worldwide.
However, this record has been broken recently. Ten new songbirds were discovered on the Indonesian islands near Sulawesi.
That was a remarkable discovery, so many new birds from one expedition, a huge success. Also, this number shows a significant increase in birds' biodiversity.
The research expedition was on Talibu, Peleng, and Batudaka islands. The majority of new birds are discovered on Talibu, the highest island of the researched group.
Finding five new species and five new subspecies of songbirds on three remote, isolated forested islands is so unexpected. But nature always finds its way to surprise us.
These small islands are part of the Wallacea region - a biogeographical designation for a group of islands, mainly Indonesians. Frank Rheindt - an evolutionary biologist at the National University of Singapore, and Dewi Prawiradilaga - an ornithologist at the Indonesian Institute of Sciences in Jakarta, led the researchers and expedition in 2013 when birds were identified as new ones.
Who would have thought that these hard-to-reach and remote islands hide so many undiscovered bird species? But, Rheindt had a good feeling, and along with his colleagues, they succeeded.

“It’s very important to pick deep-sea islands, those are the ones that are likely to have endemic species that are not shared with other landmasses,” said Frank Rheindt, at the National University of Singapore.

"Even more encouraging, the islands’ interior highlands hadn’t received much attention from European explorers or naturalists, who instead had focused on the coasts," says Frank Rheindt.

Researchers hoped to find some new wildlife species during the expedition, but they surely couldn't imagine finding 10 of them.
“We weren’t aware that this was going to be a bonanza of new species and subspecies,” says Rheindt.

Five new subspecies and five new species of birds were confirmed based on the birds' physical characteristics, DNA, and singing differences. Some of the newly identified birds were among the most visually remarkable like Taliabu Myzomela honeyeater (Myzomela wahe) with his vivid red-orange feathers and Togian jungle-flycatcher (Cyornis omissus omississimus) is a belly bird with feathers in light yellow color and a cup on its head in iridescent blue.

Rheindt’s personal favorite is Taliabu grasshopper-warbler (Locustella portenta). He says this bird is really shy and elusive. As he saw it, he had noticed that the bird was a different color than the other grasshopper-warblers in the area. Its plumages were darker, and the cricket-like song was not the same as the other grasshopper-warblers singing it.

New bird species that have been discovered in recent decades are mostly from Peru and Brazil, says Pamela Rasmussen (an ornithologist at Michigan State University in East Lansing). She added that this discovery is very “unusual in the fact that these birds have existed so long without being documented. There are very few places left that are likely to have so many [birds].”
JAMES EATON/BIRDTOUR ASIA "The cache of new birds is impressive", says Pamela Rasmussen.

There is so much on the planet that we still don't know about and although most of the mysteries that remain are likely in the vast depths of the ocean, the rest of the world will continue to amaze us at every opportunity given. Mother Nature will always have its secrets.
But thanks to curious and persistent people, our knowledge is growing. We learned that our planet is richer for ten new bird species, thanks to Frank and his team of researchers.
