This also applies to wild animals, but so far, it has not been known how long the reduced activity lasts or which activities are affected the most. New research shows that birds' activity decreases for up to three weeks when they become ill -- something that could mean the difference between life and death.

A new study has found an upper bound for the frequency that disrupts the magnetic compass.

The discovery supports predictions that over 90% of emperor penguin colonies will be quasi-extinct by the end of the century, based on current global warming trends.

A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.

It is likely that the patterns documented in this study are occurring in other large cities across the globe that have abundant asphalt, steel, and concrete with little green vegetation.

Since the yellow pigment of the breast feathers of great tits comes from the food they eat, the paler yellow plumage of urban birds indicates that the urban environment affects the entire food chain.

The method solves a nagging statistical problem by accounting for year-to-year changes in the behavior of people collecting the data.

Because of this, energy companies invest substantial time and money into making sure power lines are avian safe, installing safe perches and insulating energized elements. However, a recent study presents a new priority for conservation, as it suggests that electrocution is no longer the only leading cause of death for birds along power lines. Instead, researchers report that 66% of dead birds that were found along power lines -- for which a cause of death could be conclusively determined -- died from being illegally shot.

African cuckoos may have met their match with the fork-tailed drongo, which scientists predict can detect and reject cuckoo eggs from their nest on almost every occasion, despite them on average looking almost identical to drongo eggs.

With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others.

New research shows that pterosaurs were indeed caring parents -- but only the larger species.

Such exposure occurs when these chemicals are used to kill mice or rats, which eat the poison, and the birds eat the poisoned prey. Now, another type of rodenticide -- a neurotoxicant called bromethalin -- also can bioaccumulate in birds of prey.

New research has shown that 176 bird species around the world are now known to include a wide range of anthropogenic materials in their nests. This material found in birds' nests can be both beneficial and harmful say researchers.

The paper shows that persistent marine heat waves lead to massive seabird die-offs months later.

But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.

As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species.

Model species such as the great tit are an indispensable yardstick for our ability to predict the impact of climate change on nature. Using innovative methods, a team from the Netherlands Institute of Ecology (NIOO-KNAW) took a sneak peek into the birds' future.

In Southern Europe it is known to spread West Nile virus, but it is highly unlikely for the disease to occur in Finland. Culex modestus has become the 44th mosquito species found in Finland, and the northernmost record of the species in Europe. The previous findings closest to Finland, but further south, have been made in the Leningrad Province in Russia and in Skåne in Sweden.

So it shows a honey badger the way to the nest, who rips it open and together they share the rewards. Or so the story goes.

They devised an experiment which involved playing song recordings to receptive females and discovered that male vocal consistency -- repeating the same pattern of notes with high precision -- was the key song feature that made females sexually excited.

These shifts are faced with obstacles such as mountain ranges and coastlines. Overall, bird communities are moving towards cooler areas but not fast enough to keep up with increasing temperatures.

But how do animals feel about that? A new study details an experiment to determine whether hummingbirds are turned off by alcohol in sugar water. At 1% by volume, no. At 2% by volume, they consume much less. The implication is that hummingbirds have adjusted to small amounts of alcohol likely present in flowers and backyard feeders.

The new study suggests that the butterflies with more white spots are more successful at reaching their long-distance wintering destination. Although it's not yet clear how the spots aid the species' migration, it's possible that the spots change airflow patterns around their wings.

Latest findings, however, suggest that when pigeons sleep, they might experience visions of flight. Researchers studied brain activation patterns in sleeping pigeons, using functional magnetic resonance imaging. The study revealed that similar to mammals, most of the brain is highly active during REM sleep. However, this wake-like state might come at a cost of reduced waste removal from the brain.

Adopting another person's visual perspective is a complex skill that emerges around the age of two. A new study suggests that this ability first arose in dinosaurs, at least 60 million years before it appeared in mammals. These findings challenge the idea that mammals were the originators of novel and superior forms of intelligence in the wake of the dinosaur extinction.

An evolving system or animal is free to simply go with what works. Not so much that its performance suffers greatly, but enough that it opens access to other options near the so-called optimal design. With scientists often looking to nature for clues to solve challenges, they should also free to miss the optimal mark and open a wider design space over time.

Songbirds, many of which make twice-yearly, non-stop flights of more than 1,000 miles to get from breeding range to wintering range, fuel themselves by burning lots of fat and a surprising amount of the protein making up lean body mass, including muscle, early in the flight. This flips the conventional wisdom on its head, which had assumed that migrating birds only ramped up protein consumption at the very end of their journeys, because they would need to use every ounce of muscle for wing-flapping, not fuel.

But the strategy comes with a cost -- a decline in overall survival.

The scientists applied a new method which allowed for accurate determination of the temperature when the egg's carbonate shell was formed. Furthermore, the researchers showed that Troodon laid 4 to 6 eggs per clutch. As nests with up to 24 Troodon eggs had been found, the scientists conclude that several Troodon females laid their eggs in communal nests.

Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.

Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.
