Wild Bees Cut Their Flight Paths by 80% - Here's How They Do It
A bumblebee leaves her nest with no map, no GPS, and no instructions. By the end of the week, she'll have figured out the most efficient route between every flower patch in her territory — reducing her total flight distance by eighty percent. That's not a metaphor. Researchers tracked it with radar. In this episode of Secret Pollinators, Kelly digs into the hidden navigation science of wild bees: traplines, floral constancy, the multi-scale memory that makes it all work, and why the technology to track solitary native bees is only now catching up to the questions scientists most want to answer. Plus: what the flowers have to do with all of it.
No honey bees. All wild. All wonder.
