When you reach for the rat poisons, stop for one second and think about where it goes. Often not rats and mice. Here we demonstrate it ends up in possums, many are then eaten by predators like powerful owls.

Small audio recording devices were used to record bird songs in the forest around the clock. The photograph shows a lush, green forest and the view is up into very tall trees, looking up to the sky behind the canopies. There are no birds to be seen but there is a small, rectangular, dark-green device strapped round a tree trunk. Image thanks to David Singer who led this research.

We know when the wild birds sing

Do red squirrels and dormice get along?

Researchers discovered that they can: forests combining both deciduous and conifer trees make it easier for them to coexist: www.uni-goettingen.de/en/3240.html... #Biodiversity #Ecology
