In Texas, biologists have documented an extraordinary bird — the natural hybrid offspring of a green jay and a blue jay. Once separated by millions of years of evolution and distinct ranges, the two species were brought together as climate change expanded their territories. A backyard birder’s photo led to the discovery, and after years of elusiveness, scientists confirmed the bird’s identity through genetic testing.

Read moreA new study investigates how the success of a wild pig invasion may be dependent on how they use their surrounding food resources, and how when it comes to agriculture, the pigs continue their destructive trend.
Read moreResearchers have identified a neural pathway implicated in social interaction between adult and juvenile animals.
Read moreIdentifying how groups of animals select where to live is important for understanding social dynamics and for management and conservation. In a recent study, researchers examined the movement of a maternity colony of big brown bats as a response to naturally occurring tree loss.
Read moreThe teeth of mammals experience constant wear. However, the details of these wear processes are largely unknown. Researchers have now demonstrated that the various areas of herbivores' teeth differ in how susceptible they are to dental wear, detailing an exact chronology.
Read moreNew research finds dog owners are often inaccurate when measuring out kibble using a scoop, putting the dogs at risk of under-nourishment or weight gain.
Read moreScientists propose a new method for calculating populations of the Antillean manatee, a marine mammal in danger of extinction, through underwater recordings.
Read moreDarker male giraffes have been found to be more solitary and less social than their lighter-colored counterparts, according to new research. A long-term study revealed that the color of male giraffes' spots more strongly relates to their patterns of social association, rather than their age, as previously thought.
Read moreAn evolutionary biologist has spent more than three decades studying the skulls of many species of large carnivores — including wolves, lions and tigers — that lived from 50,000 years ago to the present. She reports today the answer to a puzzling question.
