A new study published May 1, 2023, in the Proceedings of the National Academy of Sciences found that birth rates for bird species have been declining around the world due to climate change.

More than 500 species of fish, algae, coral and invertebrates that live on Australia's reefs have declined in the past decade, according to research published in the journal Nature.

Within mammals, birds, insects and other classes of animals, there are species in which, in their sexual rituals, the males fight hand to hand to show which of them is stronger.

The Natural History Museum identified 351 new species of animals and plants. In the list, led by invertebrate animals, there are 85 species of wasps, 84 beetles, 34 moths and seven individual frogs due to their size.

We are going through a double climate crisis and biodiversity loss that threatens the well-being of all living beings. More than a tenth of Earth's plant and animal species could become extinct

Approximately 10,000 species of birds are known on Earth. Slightly less than half are migratory. A total of about 4,000 species of birds migrate back and forth between their breeding and wintering grounds.
