Successful ‘alien’ bird invasions are location dependent

June 20, 2019

This release is adapted from material prepared by University College London Whether ‘alien’ bird species thrive in a new habitat depends more on the environmental conditions than the population size or characteristics of the invading bird species, say researchers, including University of Utah ornithologist Çağan Şekercioğlu. A new study published today in Nature shows that […]



Birds retreating from climate change, deforestation in Honduras cloud forests

September 6, 2018

The cloud forests of Honduras can seem like an otherworldly place, where the trees are thick with life that takes in water straight from the air around it, and the soundscape is littered with the calls of animals singing back and forth. Otherworldly, yes, but scientists have found that the cloud forests are not immune […]



How animals holler

May 21, 2018

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 […]



Vultures reveal critical Old World flyways

April 30, 2018

It’s not easy to catch an Egyptian vulture. Evan Buechley knows. He’s hunkered down near garbage dumps from Ethiopia to Armenia, waiting for the highly intelligent birds to trigger a harmless trap. But no matter how well he and other researchers hid the traps, he says, “somehow the birds could always sense that something was […]



Citizen science birding data passes scientific muster

March 9, 2018

As long as there have been birdwatchers, there have been lists. Birders keep detailed records of the species they’ve seen and compare these lists with each other as evidence of their accomplishments. Now those lists, submitted and aggregated to birding site eBird, can help scientists track bird populations and identify conservation issues before it’s too […]



A songbird’s travelogue

September 23, 2016

Biologists at the University of Utah recently used light-weight geolocation technology to follow a species of songbird on its 10,000-kilometer migration from the Middle East to sub-Saharan Africa. The study, published October 26 in The Condor: Ornithological Applications identified key regions of importance for the species and highlighted the lack of protection many of these […]



Why birds matter

September 6, 2016

University of Utah ornithologist and biology department professor Çağan Şekercioğlu presents a new book, “Why Birds Matter,” this week at the IUCN World Conservation Congress in Honolulu. Held every four years, this is the world’s largest conservation event. Over 8300 delegates from 184 countries gathered for the meeting where President Obama made an appearance on Wednesday. Şekercioğlu […]



Why vultures matter – and what we lose if they’re gone

May 3, 2016

Vultures. Cartoon characters in parched deserts often wish them to disappear, since circling vultures are a stereotypical harbinger of death. But, joking aside, vultures in some parts of the world are in danger of disappearing. And according to a new report from University of Utah biologists, such a loss would have serious consequences for ecosystems […]



Pigeon foot feather genes identified

March 14, 2016

University of Utah scientists identified two genes that make some pigeon breeds develop feathered feet known as muffs, while others have scaled feet. The same or similar genes might explain scaled feet in chickens and other birds, and provide insight into how some dinosaurs got feathers before they evolved into birds. The study found that […]



Darwin’s finches may face extinction

December 17, 2015

Mathematical simulations at the University of Utah show parasitic flies may spell extinction for Darwin’s finches in the Galapagos Islands, but that pest-control efforts might save the birds that helped inspire the theory of evolution. The new study “shows that the fly has the potential to drive populations of the most common species of Darwin’s […]
