Crone and Williams teamed up to see how bumblebee colonies grew and reproduced across a gradient of northern California habitats in one of the first studies to quantify how bee populations respond to floral resources. They found that colonies in habitats with lots of flowers throughout the growing...

In day-to-day searching for food, for example, hummingbirds may rely on more of a bee's-eye view than a bird's-eye view. Like other birds, they rely on landmarks, distances and directions to make maps when traveling long distances, but they don't use these cues to find flowers....

Like bees and butterflies, these bats have large wings in proportion to their body size, enabling them to hover above stationary flowers and eat the delicious food with long tongues. Nectar-feeding bats visit plants that release pungent nectar only at night. They have long, narrow muzzles and...
flowers. Move a flower just an inch or so away from where a hummingbird thought it was and it will hover over the flower’s original location. Dr. Pritchard is investigating if, like bees, hummingbirds engage in view matching — hovering, scanning snapshots of a place to its memory and...
