First Known Photos of ‘Lost Bird’ Not Seen in 2 Decades are Captured by University of Texas Scientists: For the first time, scientists have captured photos of a bird in Africa that was unseen for nearly twenty years. Known as the Yellow-crested Helmetshrike, the species had been listed as a ‘lost bird’ by the American Bird Conservancy because it had not been spotted in nearly two decades. Scientists from the University of Texas at El Paso discovered a small flock of the birds during a six-week expedition to a mountain range in eastern Democratic Republic of the Congo. “It was a mind-blowing experience to come across these birds. We knew they might be possible here, but I was not prepared for how spectacular and unique they would appear in life,” said UTEP assistant professor Michael Harvey, Ph.D, an ornithologist. Harvey co-led the expedition with UTEP Professor Eli Greenbaum, Ph.D. They were joined by ornithologist Matt Brady, as well as a group of Congolese researchers from the Centre de Recherche en Sciences Naturelles. The team trekked on foot for 75 miles through the depths of the Itombwe Massif mountains, studying birds, amphibians, and reptiles along the way. While exploring the cloud forests on the slopes of a mountain, Harvey and Brady stumbled upon the helmetshrike—a striking black bird with a bright yellow “helmet.” In total, about 18 helmetshrikes appeared in noisy and active groups among the mid-layer of forest vegetation at three sites, during the expedition. The bird is endemic to the western slopes of the Albertine Rift of Central Africa, according to Harvey, a region that has been largely inaccessible due to war and security issues, but which has recently become safer to visit. “This inspires hope that perhaps the species still has a reasonably healthy population in the remote forests of the region,” Harvey said. With mining, logging, and agriculture making inroads deep into the forests of the Itombwe range, the team is in discussions with other researchers and conservation organizations to launch efforts to protect the helmetshrikes. “Right now is a golden opportunity to protect these tropical forests, so that we don’t lose species like the helmetshrike before they are known and studied,” said Harvey. The expedition, which ran from December 2023 to January 2024, yielded other important discoveries.

The herpetology team rediscovered the Red-bellied Squeaker Frog (Arthroleptis hematogaster) which had not been seen since the 1950s. This was Greenbaum’s eleventh expedition to the Democratic Republic of the Congo where he was inspired to write his book, Emerald Labyrinth: A Scientist’s Adventures in the Jungles of the Congo.The dean of the College of Science at UTEP hopes these groundbreaking discoveries will illuminate and inspire students and scientists worldwide.

Australian Turtledove

Australian turtledove (Geopelia humeralis) is native to Australia animal. Australian turtledove is protected by National Parks and Wildlife Act 1974. They include a pigeon-sized, their size varies between 26-30 cm (10.4 to 12 inches). They has distinctive and melodious voice that sounding like "cook-a-wook "or" coolicoo ". The Australian turtledoves are very graceful, with beautiful eyes circled in a strong orange color, in addition to sound good, they also having beautiful fur. Turtledove bird known for its uniqueness of his voice. Fans come from all walks of society. However, australian turtledoves are different, other than soft-spoken, their fur color is quite beautiful. So hobbyists interested to collecting, even want to get of their offspring of intercross result with other types. White speckled. The shape and size smaller than usual turtledove, and a gray body color. Her eyes circled in striking orange color, and feather wings decorated with the white spots a little rough, there are different with the African turtledove who having soft white spots. Other peculiarity of this turtledove is they has attractive appearance and soft-spoken, especially the male. Usually the male is always showing off his wing feathers in front of the female, to steal the attention of the female. The female will then approach him, then both attracted to each other. Particularity the nature and pattern of the soft fur color makes hobbyists interested to collecting this Australian turtledove. Recognize them. In the match of turtledove, you need to know and understand its properties. For example, the sound quality, the beauty of his feathers, and body shape. It is very important, if their mother are good quality, likely that his children would also be good turtledove. Moreover, if their parent is the champion turtledove, almost certainly the offspring can be the champion. Many hobbyists who tried to make intercross of gray Australian turtledove with bangkok and African turtledove. This effort is expected to generate turtledove feather color pattern and good sound..Source: The True Adventures

Website can identify birds from photos

www.eurekalert.com: In a breakthrough for computer vision and for bird watching, researchers and bird enthusiasts have enabled computers to achieve a task that stumps most humans — identifying hundreds of bird species pictured in photos.

  • It’s free: The bird photo identifier, developed by the Visipedia research project in collaboration with the Cornell Lab of Ornithology, is available for free at: AllAboutBirds.org/photoID Results will be presented by researchers from Cornell Tech and the California Institute of Technology at the Computer Vision and Pattern Recognition (CVPR) conference in Boston on June 8, reports eurekalert.com.
  • A growing database: Called Merlin Bird Photo ID, the identifier is capable of recognising 400 of the mostly commonly encountered birds in the United States and Canada. “It gets the bird right in the top three results about 90 per cent of the time, and it’s designed to keep improving the more people use it,” said Jessie Barry at the Cornell Lab of Ornithology. “That’s truly amazing, considering that the computer vision community started working on the challenge of bird identification only a few years ago.” To see if Merlin can identify the bird in your photo, you upload an image and tell Merlin where and when you took it. To orient Merlin, you draw a box around the bird and click on its bill, eye, and tail. Merlin does the rest. Within seconds, it looks at the pixels and combines powerful artificial intelligence techniques with millions of data points from humans, then presents the most likely species, including photos and sounds.
  • The devil’s in the details: Computers can process images much more efficiently than humans — they can organise, index, and match vast constellations of visual information such as the colours of the feathers and shapes of the bill,” said Serge Belongie, a professor of Computer Science at Cornell Tech. “The state-of-the-art in computer vision is rapidly approaching that of human perception, and with a little help from the user, we can close the remaining gap and deliver a surprisingly accurate solution.” Merlin’s success relies on collaboration between computers and humans. The computer learns to recognise each species from tens of thousands of images identified and labeled by bird enthusiasts. It also taps in to more than 70 million sightings recorded by birders in the eBird.org database, narrowing its search to the species found at the location and time of year when the photo was taken.
  • Better with time: Because the photo identifier uses machine learning techniques, it has the potential to improve the more people use it. After it can reliably identify photos taken with smartphones, the team will add it to the Merlin Bird ID app, a free app that has helped users with more than 1 million bird identifications by asking them five questions. Source: The Asian Age, Image: https://flickr.com
