In the world of Costa’s hummingbirds, it’s not size that matters—it’s sound. During breeding season, male Costa’s perform a high-speed dive during which they “sing” to potential mates using their tail feathers.

Cheetahs in the Serengeti National Park adopt different Two male cheetahs eat a killstrategies while eating to deal with threats from to​​​​​​​p predators such as lions or hyenas. A new study in Springer’s journal Behavioral Ecology and Sociobiology shows that male cheetahs and single females eat their prey as quickly as possible. Mothers with cubs, on the other hand, watch out for possible threats while their young are eating in order to give them enough time to eat their fill. The research was led by Anne Hilborn of Virginia Tech’s College of Natural Resources and Environment in the US.

New research suggests that species that live on green roofs arrived by hitching lifts on birds or by riding air currents.

A graduate student at the University of Alberta has developed an automated system for detecting owl calls, eliminating the need for researchers to spend nights in the field.

The recent death of the last male Northern white rhinoceros — and the imminent extinction of the vaquita porpoise — is a stark reminder we are not going to win every battle to save endangered species in the wild. We can rescue some from total extinction — and have already — but only with the help of zoos and aquariums.

LSU researchers have discovered a new relationship between climate change, monarch butterflies and milkweed plants. It turns out that warming temperatures don’t just affect the monarch, Danaus plexippus, directly, but also affect this butterfly by potentially turning its favorite plant food into a poison.

Control efforts such as the removal of shipwrecks and application of chlorine may help mitigate the damaging effects of corallimorph, which is a type of invasive anemone, on valuable coral reefs in the Central Pacific Ocean, according to a new U.S. Geological Survey study.

Norfolk’s butterflies, bees, bugs, birds, trees and mammals are at major risk from climate change as temperatures rise – according to new research from the University of East Anglia.

Insights into how songbirds learn to sing provide promising clues about human speech disorders and may lead to new ways of treating them, according to new research published in the journal eLife.

Researchers from the University of Sheffield have discovered that looking at honeybees in a colony in the same way as neurons in a brain could help us better understand the basic mechanisms of human behaviour.
