Vegetarian birds more sociable than insect eaters
Weaver birds that eat seeds flock together and nest in colonies more commonly than those species that eat insects, suggests new research by an international team of scientists led by the Milner Center for Evolution at the University of Bath. For the.....»»
Tropical forests can"t recover naturally without fruit eating birds, carbon recovery study shows
New research from the Crowther Lab at ETH Zurich illustrates a critical barrier to natural regeneration of tropical forests. Their models—from ground-based data gathered in the Atlantic Forest of Brazil—show that when wild tropical birds move fre.....»»
Yellow-eyed grasses may have more insect visitors than previously thought
Scientists previously believed that a family of flowering plants called yellow-eyed grasses didn't attract many insect visitors, but the recent discovery of a fungus that hijacks the plant and forms fungal "pseudoflowers" has researchers rethinking t.....»»
What do bird dreams sound like?
For more than 20 years, researchers have known that areas of birds' brains dedicated to singing show neural patterns during sleep akin to the ones they use while awake and singing......»»
Scientists find blue light makes buildings more deadly to migrating birds
Bird collisions with buildings are nothing new, but a new study by scientists at The University of New Mexico sheds light on a potential cause......»»
Oxidant pollutant ozone removes mating barriers between fly species, study finds
Insect pheromones are odor molecules used for chemical communication within a species. Sex pheromones play a crucial role in the mating of many insects. Species-specific odors attract males and females of the same species. At the same time, they main.....»»
Climate change has positive and negative effects on invasive mountain pine beetles
Climate change is hampering mountain pine beetle reproduction but also appears to slightly benefit the invasive insect in other ways, new University of Alberta research shows......»»
How insect blood stops bleeding fast
Their blood equivalent, hemolymph, forms a viscoelastic fluid that covers wounds. Enlarge (credit: Weber) What if human blood turned into a sort of rubbery slime that can bounce back into a wound and stop it from bleedin.....»»
Two sex pheromone receptors for sexual communication found in the American cockroach
Sex pheromones are vital in facilitating the chemical communication that underpins insect courtship and mating behavior. Among female American cockroaches (Periplaneta americana), two key volatile sex pheromone components, periplanone-A (PA) and peri.....»»
Rusty-patched bumblebee"s struggle for survival found in its genes
A team of researchers has uncovered alarming trends in the first range-wide genetic study of an endangered bee species. The study, led by Colorado State University and published in the Journal of Insect Science, will inform conservation and recovery.....»»
Automated bioacoustics: Researchers are listening in on insects to better gauge environmental health
Recent research led by the University of Massachusetts Amherst evaluates how well machine learning can identify different insect species by their sound, from malaria-carrying mosquitoes and grain-hungry weevils to crop-pollinating bees and sap-suckin.....»»
Dog-like Spot robot gets a gig to scare wildlife
An international airport is deploying a dog-like robot to scare birds and other wildlife from encroaching the runway......»»
After 10 years of work, landmark study reveals new "tree of life" for all birds living today
The largest-ever study of bird genomes has produced a remarkably clear picture of the bird family tree. Published in the journal Nature today, our study shows that most of the modern groups of birds first appeared within 5 million years after the ext.....»»
A frozen chunk of genome rewrites our understanding of bird evolution
An enormous meteor spelled doom for most dinosaurs 65 million years ago. But not all. In the aftermath of the extinction event, birds—technically dinosaurs themselves—flourished......»»
Small birds spice up the already diverse diet of spotted hyenas in Namibia
Spotted hyenas are known for hunting (or scavenging) larger mammals such as antelopes and occasionally feed on smaller mammals and reptiles. Being flexible in the choice of prey is a strategy of generalists—and this even extends to small passerine.....»»
The Earth Will Feast on Dead Cicadas
Two cicada broods, XIX and XIII, are emerging in sync for the first time in 221 years. Birds, trees, and dirt are about to get the banquet of a lifetime......»»
How Spanish conquistadors, and a tiny cactus-dwelling insect, gave the world the color red
When you think about a red object, you might picture a red carpet, or the massive ruby in the Queen's crown. Indeed, Western monarchies and marketing from brands such as Christian Louboutin have cemented our association of the color red with power an.....»»
Cows in Texas and Kansas test positive for highly pathogenic bird flu
The risk to the public is low, and the milk supply is safe. Enlarge (credit: Getty | Peter Cade) Wild migratory birds likely spread a deadly strain of bird flu to dairy cows in Texas and Kansas, state and federal officia.....»»
Solar eclipse could scramble bird behavior
On April 8, the shadow of a total solar eclipse will race across North America. At the same time, researchers from the Cornell Lab of Ornithology and partners will be hurrying to measure the impact of daytime darkness on the movements of birds, bats,.....»»
Early spring, earlier nesting birds
Did spring arrive early this year? Some people think so. Apparently, some birds do, too. The NestWatch project at the Cornell Lab of Ornithology documents when and where birds are nesting......»»
In a first, evolutionary biologists have identified a gene that influences visual preferences in tropical butterflies
Tropical Heliconius butterflies are well known for the bright color patterns on their wings. These striking color patterns not only scare off predators—the butterflies are poisonous and are distasteful to birds—but are also important signals duri.....»»
