🐺📸 When the model knows exactly where the camera is. These wolves from the Oder Delta (Poland) delivered a perfect pose for our camera trap. While most wildlife pass by unnoticed, some seem determined to leave us with a memorable portrait.

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. Please avoid second generation anticoagulants 🙏♥️🦉 www.sciencedirect.com/science/arti...

We know when the wild birds sing Researchers used automatic audio recorders and AI to collect and identify detailed data about birdsong in European Forests. It turned out it was more than just larks and owls: www.uni-goettingen.de/en/3240.html... #JournalOfOrnithology: doi.org/10.1007/s103...
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.A tiny, grey-brown bird with wide open beak perching at the top of a stump of wood with blurred yellow/green (likely) tree foliage in the background.
