Bees with backpacks.

Researchers are using tiny radio trackers attached to eastern bumblebee queens in Cambridge, Ont., to study their movement, behavior, and habitat choices. The trackers, resembling backpacks, transmit signals to 44 radio towers to record precise locations, revealing surprising findings about pesticide effects on bee movement and nocturnal flights. Preliminary observations suggest that bumblebees prefer naturalized areas for habitat selection, and researchers hope to learn more about this under-studied species as they follow the bees to their hibernation spots.
