Variations of a Single Gene Drive Diverse Pigeon Feather Patterns

University of Utah

In a new study, biologists have discovered that different versions of a single gene, called NDP (Norrie Disease Protein), have unexpected links between color patterns in pigeons, and vision defects in humans. The gene variations were likely bred into pigeons by humans from a different pigeon species and are now evolutionarily advantageous in wild populations of feral pigeons living in urban environments.

Biodiversity Research Institute Announces Critical Findings From 5-Year Restore the Call Loon Research Study

Biodiversity Research Institute (BRI)

Biodiversity Research Institute (BRI) announces results of its five-year loon study Restore the Call: a male loon chick that was translocated in 2015 from the Adirondack Park Region of New York to the Assawompsett Pond Complex (APC) in southeastern Massachusetts has returned to the APC lake from which it fledged. The identification of this loon (through color bands) marks the first confirmed account of an adult loon returning to the lake to which it was translocated, captive-reared, and then fledged.

Asteroid Impact Grounded Bird Ancestors

Cornell University

An international team of scientists has concluded the asteroid that smashed into Earth 66 million years ago not only wiped out the dinosaurs, but erased the world’s forests and the species that lived in trees. The researchers say only small ground-dwelling birds survived the mass extinction, profoundly changing the course of bird evolution.

How Animals Holler

University of Utah

While humans can only broadcast about one percent of their vocal power through their speech, some animals and mammals are able to broadcast 100 percent. The secret to their long-range howls? A combination of high pitch, a wide-open mouth and a clever use of the body’s shape to direct sound – none of which are factors that humans can replicate.

Vultures Reveal Critical Old World Flyways

University of Utah

Identifying bottlenecks — i.e. places where birds concentrate on migration — helps bird conservationists know what areas to focus on and get the most bang for their buck, since a large percentage of a species’ population can pass through these small areas.
