Newswise: Following the lizard lung labyrinth

Following the lizard lung labyrinth

University of Utah

Mammals inhale oxygen-rich air and they exhale depleted air, exhibiting a so-called tidal flow pattern. In contrast, bird breath travels through part of the respiratory system, but in a one-way loop throughout most of the lung. Biologists have discovered that Savannah monitor lizards have lung structures that are hybrid system of bird and mammal lungs.

Watch on Live Camera As a Baby Albatross Grows Up

Cornell University

Millions of people from around the world can now witness a rare sight in real time: a Northern Royal Albatross pair nesting and raising their chick. The live views originate from a coastal albatross colony in Otago, on South Island, New Zealand, and are made possible by a new partnership between the country's Department of Conservation (DOC) and the Cornell Lab of Ornithology.

Newswise: Insects’ Drag-Based Flight Mechanism Could Improve Tiny Flying Robots

Insects’ Drag-Based Flight Mechanism Could Improve Tiny Flying Robots

American Institute of Physics (AIP)

Thrips don’t rely on lift in order to fly. Instead, the tiny insects rely on a drag-based flight mechanism, keeping themselves afloat in airflow velocities with a large ratio of force to wing size. In a study published in this week’s Journal of Applied Physics, researchers performed the first test of the drag force on a thrip’s wing under constant airflow in a bench-top wind tunnel. Drawing from experience in microfabrication and nanomechanics, they created an experiment in which a thrip’s wing was glued to a self-sensing microcantilever.

National Park Service Scientists: Does Aircraft Noise Make Birds More Vocal?

Acoustical Society of America (ASA)

National Park Service scientists analyzed nearly 1 million 10-second audio recording samples from national parks across the country and discovered a small increase in bird sound detection when an aircraft sound is also detected. During the 178th ASA Meeting, Kurt Fristrup will present the findings and how human responses to noise might be studied.

Young tree swallows carry environmental stress into adulthood

Cornell University

Cornell University researchers have found that colder temperatures during tree swallows' development stage has an effect on swallows later in life.

Newswise: Birds of a Feather Flock Together, But How Do They Decide Where to Go?

Birds of a Feather Flock Together, But How Do They Decide Where to Go?

American Institute of Physics (AIP)

Coordinated behavior is common in a variety of biological systems, such as insect swarms, fish schools and bacterial colonies. But the way information is spread and decisions are made in such systems is difficult to understand. A group of researchers from Southeast University and China University of Mining and Technology studied the synchronized flight of pigeon flocks. They used this as a basis to explain the mechanisms behind coordinated behavior, in the journal Chaos.

Newswise: Uncover Secrets of Nesting Birds With “Nest Quest Go!”

Uncover Secrets of Nesting Birds With “Nest Quest Go!”

Cornell University

Secrets hidden in more than 300,000 index cards with hand-written information about nesting birds are gradually being revealed. The Cornell Lab of Ornithology is partnering with Zooniverse, an online people-powered research tool, to digitize this valuable collection and create the largest database of nesting bird information in the U.S. This new effort is called "Nest Quest Go!"
