New research has resulted in an updated evolutionary tree of early birds and their closest relatives to reconstruct powered flight potential, showing it evolved at least three times. Many ancestors of the closest bird relatives neared the thresholds of powered flight potential, suggesting broad experimentation with wing-assisted locomotion before flight evolved.

Scientists have used mathematical modelling to understand why flocks of long-tailed tits segregate themselves into different parts of the landscape. View the full article

A new study of captured mosquitoes in Los Angeles finds that West Nile infection is strongly associated with average temperature, and that temperatures above 73 degrees Fahrenheit are highly favorable for West Nile transmission. As climate change brings hotter weather to the region, it is likely that cooler, coastal neighborhoods will be pushed into the 'favorable' zone, accelerating transmission of the virus.

A new analysis examines whether bacteria, viruses, and other microorganisms that are present in wild vultures cause disease in the birds, and whether vultures play a role in spreading or preventing infectious diseases to humans and other animal species. View the full article

Plucky, beautiful and declining in numbers at about a 2% annual rate, the rufous hummingbird makes its long annual migration in different timing and route patterns based the birds' age and sex, new research shows. View the full article

Humans have a hard time identifying individual birds just by looking at the patterns on their plumage. An international study has now shown how computers can learn to differentiate individual birds of a same species. View the full article

Forest ecologist report finding ''clear evidence of a contraction of the breeding period'' among boreal birds in Finland over a 43-year span for which good quality data were available. View the full article

The global population of the critically endangered Chinese crested tern has more than doubled thanks to a historic, collaborative, decade-long study. View the full article

New research has revealed when it comes to flying the largest of birds don't rely on flapping to move around. Instead they make use of air currents to keep them airborne for hours at a time. A study has revealed the Andean condor - the world's heaviest soaring bird - actually flaps its wings for one per cent of its flight time. View the full article

Although carrion crows and hooded crows are almost indistinguishable genetically, they avoid mating with each other. Researchers have now identified a mutation that appears to contribute to this instance of reproductive isolation. View the full article

Every spring, a large number of ground-nests of farmland birds are accidentally destroyed by mechanical operations, such as ploughing and sowing. A new study shows for the first time that such nests can be located using a drone in combination with artificial intelligence. View the full article

Caspian terns feeding on young fish have a significant impact on runs of steelhead in the Columbia River, new research suggests. View the full article

A trip to Jicarón Island during the Coiba Bioblitz led to a published bird checklist. View the full article

New insight on how four species of seabirds have developed the ability to cruise through both air and water has just been published. View the full article

The latest supplement to the American Ornithological Society's Checklist of North and Middle American Birds includes several major updates to the organization of the continent's bird species, including the addition of the Mexican Duck and the removal of the Northwestern Crow. The official authority on the names and classification of the region's birds, the checklist is consulted by birdwatchers and professional scientists alike and has been published since 1886.

Suspended, rotating devices known as ''flappers'' may be the key to fewer birds flying into power lines, a new study suggests. View the full article

A new study of albatrosses has found that wind plays a bigger role in their decision to take flight than previously thought, and due to their differences in body size, males and females differ in their response to wind. View the full article

While humans have three color cones in the retina sensitive to red, green and blue light, birds have a fourth color cone that can detect ultraviolet light. A research team trained wild hummingbirds to perform a series of experiments that revealed that the tiny birds also see combination colors like ultraviolet+green and ultraviolet+red.

Bird feeding helps females more than males
ScienceDaily posted a topic in Bird Research in the Media
A new study shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as much as they would have otherwise, and the chances of surviving cold nights increase. View the full article -
Organisms carry long-term 'memories' of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site. View the full article

A new study has confirmed and quantified, for the first time, the presence of microplastics in terrestrial and aquatic birds of prey in Florida, including hawks, ospreys and owls. The research is important because birds of prey are critical to a functioning ecosystem. The accumulation of microplastics in their digestive systems could lead to poisoning, starvation and death.

As the world looks to tighten up the illegal capture of wildlife, migratory birds are being threatened by widespread and unsustainable hunting across the Asia-Pacific region. New research has revealed that three quarters of migratory shorebird species in the region have been hunted since the 1970s. View the full article

In a new study, researchers from the University of Copenhagen have demonstrated that penguins in Antarctica emit copious amounts of nitrous oxide via their feces. So much so, that the researchers went ''cuckoo'' from being surrounded by penguin poop. View the full article

Urban insect populations would need to increase by a factor of at least 2.5 for urban great tits to have same breeding success as those living in forests according to new research. View the full article
