"Each spring, they migrate up to 1000 kilometres to remote #caves in the #AustralianAlps... In a 2018 study, researchers discovered the bogong #moth can sense the Earth’s magnetic field and use it as a guide... It turns out the magnetic field is a backup navigational aid the #moths rely on during cloudy conditions when the stars aren’t visible."

"When the warmer days of spring spread across the country, billions of #BogongMoths up stakes and fly, unerringly and only at night, up to 1,000 km to a place they have never been before: the cool #caves high in the #AustralianAlps... they use the starry sky without any additional cues to fly in that direction"

The Australian Alps receive more snow than the Swiss Alps.

Worth reading Richard Barnes on ‘Devastation and blindness in our High Country’

Highlights snowgum death and decline, and reduction in natural snow fields and increasing resort to artificial snow making for ski runs.

While those who use the ski fields, many people of influence, appear blind to taking the actions necessary to address #globalWarming.
