Australian bird of the year 2025: vote for your favourite #birdoftheyear in the Guardian / BirdLife Australia poll From little penguins to (very big) cassowaries, every bird has its fans. Vote for your favourite in the 2025 Guardian/BirdLife Australia poll

Reminder to vote each day (until 15 October) for Baudin's black cockatoo as Australiaโ€™s bird of the year.

Its jarrah habitat in Western Australia is about to be cleared for bauxite mining. Every bit of attention this endangered bird gets could help it continue to exist ๐Ÿชถ ๐Ÿ‡ฆ๐Ÿ‡บ๐Ÿงช

Detail of the base of the standing stone. On the thin face are carved mermen and people with swords. On the broad face at the base are a series of gashes in the stone, left by ancient warriors as part of an oath-taking ceremony.

For #StandingStoneSunday the magnificent Suenoโ€™s Stone. Likely named for the Dane Sweyn Forkbeard, but dating to the late 800s Pictish Fortriu kingdom.

Itโ€™s over 6 metres tall, with scenes of battle and beheading. The base has sword cuts from warriors pledging to their king ๐Ÿบ๐Ÿงช๐Ÿ‘‘

Jane Goodall was also the first to bring attention to wild tool-using vultures, which she spotted randomly one day while out driving. These birds use stones to break into ostrich eggs.

Be observant like Jane and who knows what youโ€™ll see! ๐Ÿงช๐Ÿฅš

Jane Goodall convinced a reluctant world that apes use tools, then became one of the great environmentalists. She never gave up hope for a better world, and was an inspiration to all who met her, including children worldwide.

Thank you Jane.

A tall stone column in the centre of a spacious octagonal room, supporting a vaulted stone ceiling with radiating supports. Intricate glass windows are on each wall, with slightly different designs. A low bench with blue cushioning runs around the lower part of the walls.

The same room as the previous photo, looking straight up at the vaulted ceiling from beside the central column. The impression is like looking at a stone star, or spiderweb.

Your daily reminder that tool use is not about โ€˜intelligenceโ€™ or having hands. Itโ€™s about a coincidence of object and actor with time to explore and a need to fill.

Somehow, somehow the knowledge of where to go and when to leave is encoded in the genes of the green darner dragonfly.

Lizards are famous for their ability to detach their tails under stress. But how do they manage to drop them so quickly, and why do they never seem to accidentally lose their tails if they come off so easily?

#SciArtSeptember 13 - Bottleneck

We almost lost the last wild horses. At the end of the 1950s, there were only 12 Przewalski's horses left.

After decades of conservation efforts, there are now a couple thousand horses living in zoos and conservation areas in several countries, from Spain to China.
