The Arctic is warming at approximately twice the global rate. A new study finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/SlWxnZVhoIo View the full article -
Neuroscientists have demonstrated in new research that dopamine plays a key role in how songbirds learn complex new sounds.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/9hhfRA1rbiw View the full article

Following habitat-destroying wildfires, researchers found many male red-backed fairywrens failed to molt into their ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers. The birds' fat stores and stress hormone corticosterone remained at normal levels. While the findings are specific to this songbird, they may have implications for other species that don special coloration for mating.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/s4J3Uc9vLtU View the full article

Researchers provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/JNn36U8RVBc View the full article

An incredibly rare hybrid warbler with mismatched color patterns has allowed researchers to disentangle the genetic drivers of two traits that usually come as a package deal -- the black face mask and the black throat patch in blue-winged and golden-winged warblers.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/3Q9Ryyhs5Xo View the full article

Researchers have some good news for the well-meaning masses who place bird feeders in their yards: The small songbirds who visit the feeders seem unlikely to develop an unhealthy reliance on them.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/T6g9gUTkC7Y View the full article

If you listen to songbirds, you will recognize repeated melodies or phrases. Each phrase is made up of distinct sounds, strung together. A study has found that the song phrases of many songbird species follow patterns that are similar to those used in human speech. At least in some respects.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/XrlHy3pkDGc View the full article

When a research team reported last year that North American migratory birds have been getting smaller over the past four decades and that their wings have gotten a bit longer, the scientists wondered if they were seeing the fingerprint of earlier spring migrations.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/pZuRj7QA2rw View the full article

It is possible to re-create a bird's song by reading only its brain activity, shows a first proof-of-concept study. The researchers were able to reproduce the songbird's complex vocalizations down to the pitch, volume and timbre of the original. The study is a first step towards developing vocal prostheses for humans who have lost the ability to speak.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/fiARQjNr-_8 View the full article

Ecologists are urging coastal communities to embrace all that the season brings, including the sometimes-unwelcome deposits of brown seaweed that can accumulate on the southern shores.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/Zvbn7Ab4RJg View the full article

Ancient chickens lived significantly longer than their modern equivalents because they were seen as sacred -- not food -- archaeologists have found.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/19dZCXojwQ8 View the full article

Researchers set out to learn how extreme winter cold and heat affected 41 common bird species in eastern North America. They found that individual bird species respond differently to these weather events, and extreme winter heat may lead to longer-term changes in bird populations.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/kzKciC3qHIE View the full article

The white-tailed sea eagle is known for reacting sensitively to human disturbances. Forestry and agricultural activities are therefore restricted in the immediate vicinity of the nests. However, these seasonal protection periods are too short in the German federal States of Brandenburg (until Aug. 31) and Mecklenburg-Western Pomerania (until July 31), as a new scientific analysis by a team of scientists suggests.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/t0dLBBW-3kE View the full article

A team has discovered the method ducks use to suspend water in their feathers while diving, allowing them to shake it out when surfacing. The discovery opens the door for applications in marine technology.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/AY6kKKulhtE View the full article

Dark 'eyeliner' feathers of peregrine falcons act as sun shields to improve the birds' hunting ability, a new scientific study suggests. Scientists have long speculated that falcons' eye markings improve their ability to target fast-moving prey, like pigeons and doves, in bright sunlight. Now research suggests these markings have evolved according to the climate; the sunnier the bird's habitat, the larger and darker are the tell-tale dark 'sun-shade' feathers.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/OeD7f4HZM2s View the full article

Researchers say that the auditory feedback exchanged between wrens during their opera-like duets momentarily inhibits motor circuits used for singing in the listening partner, which helps link the pair's brains and coordinate turn-taking for a seemingly telepathic performance. The study also offers fresh insight into how humans and other cooperative animals use sensory cues to act in concert with one another.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/1kFSEhCN6hA View the full article

'Pretty' parrots are more likely to be snatched up for Indonesia's illegal wildlife trade, a new study reveals. The findings not only expose the key drivers behind the country's illegal trade in these birds, but offer lessons for the potential emergence and spread of infectious diseases that jump from animals to humans.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/Lz1PY0pT7NM View the full article

Neuroscientists examining genetically identified neurons in a songbird's forebrain discovered a remarkable landscape of physiology, auditory coding and network roles that mirrored those in the brains of mammals.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/4UTBmOF-LKY View the full article

The wild California condor population dropped to 22 before rescue and captive breeding allowed reintroduction into the wild. A new assembly of the complete genome of the bird reveals some inbreeding as a result, but overall high genomic diversity attesting to large populations of condors in the past, likely in the tens of thousands. Comparison to Andean condor and turkey vulture genomes reveals declines in their populations also, and lower genomic diversity than California condor.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/tMANeq28Qa8 View the full article

Traffic noise leads to inaccuracies and delays in the development of song learning in young birds. They also suffer from a suppressed immune system, which is an indicator of chronic stress. A new study shows that young zebra finches, just like children, are particularly vulnerable to the effects of noise because of its potential to interfere with learning at a critical developmental stage.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/rh6mjAq26qc View the full article

Free from human disturbance for a century, an inland island in Central America has nevertheless lost more than 25% of its native bird species since its creation as part of the Panama Canal's construction, and scientists say the losses continue.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/QRfQ284VGVA View the full article

Considered extinct as a breeding species in the early 2000s, the Saker Falcon was recovered when the first active nest from the new history of the species in Bulgaria was discovered in 2018, built by two birds that were reintroduced back in 2015.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/birds/~4/NQFLfBKy0u4 View the full article
