Ornithologists have described a new bird species from the subantarctic islands

Ornithologists have described a new species of bird that lives on the Diego Ramirez Islands south of South America. It is called the subantarctic rayadito. In the past, the local population was thought to be the spiny-tailed rayadito, which is widespread in Chile and Argentina. However, the analysis showed that individuals from the Diego Ramirez… Continue reading Ornithologists have described a new bird species from the subantarctic islands

Stingrays can make sounds. They clicked on the divers

Zoologists have demonstrated for the first time that wild stingrays can make sounds. The researchers made this conclusion after analyzing video recordings of stingrays Urogymnus granulatus And Pastinachus ater they clicked warningly when divers approached them. How noted in an article for a magazine Ecology Stingrays probably use clicks to scare away predators. At the… Continue reading Stingrays can make sounds. They clicked on the divers

An amateur ornithologist rediscovered a bird hidden for 124 years

Amateur ornithologist Michael Smith discovered a bird that had eluded researchers for 124 years. We are talking about the Louisiadian pitta, endemic to the inaccessible island of Rossel east of New Guinea. Smith observed the elusive birds and took several photographs. In addition, he recorded the voice of the Louisiada pitta – and posted the… Continue reading An amateur ornithologist rediscovered a bird hidden for 124 years

Paleontologists have described Europe's last giant tortoise. She lived in Sicily 12.5 thousand years ago

Paleontologists have discovered the bones of Europe's last giant tortoise in Sicily. The species named Solitudo sicula, lived about 12.5 thousand years ago. It was previously believed that giant tortoises went extinct in continental Europe two million years ago, and on the Mediterranean islands about two hundred thousand years ago. Probably, like other species of… Continue reading Paleontologists have described Europe's last giant tortoise. She lived in Sicily 12.5 thousand years ago

White sharks left the area of ​​Hansbaai because two killer whales were eating their livers

Two male killer whales who settled near the South African town of Hansbaai have learned to hunt white sharks and eat their energy-rich livers. To survive, white sharks had to leave the region where they had recently met regularly. But here the number of smaller narrow-toothed sharks has increased, which have lost their main enemies… Continue reading White sharks left the area of ​​Hansbaai because two killer whales were eating their livers

Lava from last year's eruption on La Palma turned out to be extremely fluid

On the Canary island of La Palma, very fluid lava erupted in 2021 – geologists came to this conclusion after observing the volcano from an observation deck, studying local television footage and analyzing ash samples. The viscosity of the Cumbre Vieja magma was estimated based on chemical composition, crystallinity, and temperature. The work showed that… Continue reading Lava from last year's eruption on La Palma turned out to be extremely fluid

The mating colors of chameleons introduced to Hawaii have become brighter in the absence of predators.

Zoologists have discovered that male Jackson's chameleons, introduced to the Hawaiian island of Oahu, display brighter colors during mating displays than their relatives from East Africa, where the species originates. This is probably due to the almost complete absence of predators dangerous to lizards on the island. As a result, male chameleons can afford brighter… Continue reading The mating colors of chameleons introduced to Hawaii have become brighter in the absence of predators.

The Tasmanian snail, thought to be extinct, has been rediscovered after 120 years.

Australian scientists discover tiny snails in Tasmania's Great Lake Beddomeia tumida, which were considered extinct since the beginning of the 20th century. According to ABC News, in total, researchers managed to find 15 specimens of the rare species. These mollusks may even be numerous, but they hide very well. Many people are concerned about the… Continue reading The Tasmanian snail, thought to be extinct, has been rediscovered after 120 years.

The female-scented inflorescences of the same-flowered plants have become death traps for male pollinators.

The inflorescences of female plants of the araceae family are deadly traps for pollinators. Once inside, the insects leave the pollen they brought on the stigmas of the flowers and, not finding a way out, die. Japanese botanist Kenji Suetsugu suggested that moths attract male pollinators by imitating the scent of females. This explains why… Continue reading The female-scented inflorescences of the same-flowered plants have become death traps for male pollinators.

The evolutionary success of ravens and crows was explained by long wings and large bodies and brains

Genus Corvus , uniting more than 45 species of ravens, crows and rooks, is considered the largest in the corvid family, and its representatives inhabit all continents except South America and Antarctica. Ornithologists have found that the evolutionary success of the genus is associated with long wings, which allow them to spread over long distances,… Continue reading The evolutionary success of ravens and crows was explained by long wings and large bodies and brains
