Check out my two most recent blog posts for the AAAS Member Central website: ‘Acoustic Ecology: Wild Sounds in Wild Places’ ( pdf or link ) and ‘The Omaha Tiger Project’ ( pdf or link ). These two posts were both inspired by a conference I attended last month: the 3rd International Symposium on Acoustic Communication by Animals in Ithaca, NY.
The concept of counting is beyond most animals – but not hyenas, new research shows . Sarah Benson-Amram and colleagues from Michigan State University played recorded calls of unknown hyenas to members of hyena clans in Masai Mara National Reserve in Kenya. Unknown hyenas are seen as potential intruders, so the ability to count their numbers and understand the size of the potential threat would be useful in determining whether to fight or back down.

Try to guess what drugs the mice are on before pointing at them. My favorite is the slow pelvic-thrusting mouse.
