Asian Waterbird Census (AWC)

The Asian Waterbird Census (AWC) is an integral part of International Waterbird Census. The international census is conducted in 143 countries.
The AWC is jointly held by Wetlands International and Bombay Natural History Society. AWC is held in the month of January every year. During the census, the volunteers visit the wetlands and count the waterbirds. The major regions covered under AWC are Southeast Asia, Australasia, East Asian – Australasian Flyway, region between Afghanistan and Japan. It was started in 1987. In 2021, the AWC reported that the overall waterbird population dipped by four times as compared to 2020.

Chilika Water Bird Status Survey - 2022

The Odisha Wildlife Organization conducted a bird census in the Chilika Lake. The organization was joined by Chilika Development Authority and Bombay Natural History Society.
Chilika is the largest brackish water lake in India, spread over the Puri, Khurda and Ganjam districts of Odisha state. Birds come to the lake to spend their winter. Around 106 personnel were deployed in the survey. This included bird experts from non – governmental organizations and government organisations. The lake was divided into 21 segments to conduct the census.
The 2022 survey witnessed 10,74,173 birds. This included the uncommon and rare Mongolian gull as well. Around 107 water bird species and 76 wetland dependent species were spotted.

Jump in Deforestation of World's most Biodiverse Savanna

Deforestation last year rose to the highest level since 2015 in Brazil's Cerrado, prompting scientists to raise alarm over the state of the world's most species-rich savanna, a major carbon sink that helps to stave off climate change.
The Cerrado, which is spread across several states of Brazil and is one of the world's largest savannas, is often called an "upside-down forest" because of the deep roots its plants sink into the ground to survive seasonal droughts and fires. Destruction of these trees, grasses and other plants in the Cerrado is a major source of Brazil's greenhouse gas emissions, although it is far less densely forested than the more famous Amazon rainforest that it borders.

Doomsday Glacier" Threat

Antarctica's Thwaites Glacier, sometimes referred to as the Doomsday Glacier, is retreating rapidly as a warming ocean slowly erases its ice from below, leading to faster flow, more fracturing, and a threat of collapse, according to an international team of scientists. The glacier is the size of Florida or Britain and currently contributes four percent of annual global sea level rise. If it does collapse, global sea levels would rise by several feet—putting millions of people living in coastal cities in danger zones for extreme flooding.
Thwaites is the widest glacier in the world. It's doubled its outflow speed within the last 30 years, and the glacier in its entirety holds enough water to raise sea level by over two feet. And it could lead to even more sea-level rise, up to 10 feet, if it draws the surrounding glaciers with it.

Perfectly Preserved Dinosaur Embryo Found in China

Scientists in China have found a perfectly preserved fossilised dinosaur embryo that was preparing to hatch from an egg.
As per reports, the egg was found in Ganzhou in southern China's Jiangxi province. Researchers estimate that the fossil is at least 66 million years old.
The embryo is believed to be of a toothless theropod dinosaur, or oviraptorosaur, and was named Baby Yingliang.
The discovery has given researchers a greater understanding of the link between dinosaurs and modern birds.
This indicates that such behaviour in modern birds first evolved and originated among their dinosaur ancestors.
