Science

Ornithology is a branch of zoology that concerns the methodological study and consequent knowledge of birds with all that relates to them. A wide range of tools and techniques are used in ornithology, both inside the laboratory and out in the field. Most biologists who consider themselves to be “Ornithologists” study specific categories, such as Anatomy, Taxonomy, or Ecology lifestyles and behaviors. — Wikipedia

Tropical ecosystems are famous for their teeming, exuberant diversity. In fact, the dramatic increase in biodiversity from the poles to the tropics—known as the latitudinal diversity gradient—is pervasive across branches of the tree of life, and fossil evidence suggests it has existed for millennia.
Crow experiments suggest switching to vocal...

For animals that can produce vocalizations, choosing to emit a sound involves various neural processes. For instance, it entails controlling when to emit a sound and how loud and high-pitched the sound will be, while also adaptively switching between vocalizations and other behaviors in response to changing circumstances.

University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average to identify the direction in which a dot pattern was moving and to indicate their choice—while maintaining a high degree of accuracy.

Less favorable ocean conditions mean marbled murrelet chicks take longer to leave the nest, making them more vulnerable to predation, according to a new study of the Pacific Northwest seabird by Oregon State University scientists.
