(TMU) – Wildlife researchers in New Mexico and Colorado are aghast as a growing number of birds across the region are being discovered to have mysteriously died off in massive numbers.
In recent days, residents across the region have been finding the corpses of various migratory birds along hiking trails, missile ranges, and other locations.
Experts remain unclear about why exactly the huge die-off is occurring, although some believe that it could possibly be tied to a recent cold front, ongoing droughts, or even the tremendous amount of smoke being pumped out of the wildfires across western states.
“It is terribly frightening,” Prof. Martha Desmond of New Mexico State University’s Department of Fish, Wildlife and Conservation Ecology told Las Cruces Sun-News. “We’ve never seen anything like this. … We’re losing probably hundreds of thousands, if not millions, of migratory birds.”
Desmond and a team of wildlife experts at the Bureau of Land Management, NMSU, and White Sands Missile Range have been trying to ascertain the drastic and unexpected rise in bird deaths.
The impacted bird species include blackbirds, warblers, sparrows, swallows, flycatchers, and the western wood pewee.
“A number of these species are already in trouble,” Desmond said. “They are already experiencing huge population declines and then to have a traumatic event like this is – it’s devastating.”
“People have been reporting that the birds look sleepy … they’re just really lethargic,” said Trish Cutler, a biologist at White Sands Missile Range.. “One thing we’re not seeing is our resident birds mixed in with these dead birds. We have resident birds that live here, some of them migrate and some of them don’t, but we’re not getting birds like roadrunners or quail or doves.”
The cold snap that passed through the state is being looked at as one potential reason for the deaths.
However, Desmond told KOB that “What is odd is the fact that we’re seeing this occur beforehand and we’re seeing it occur since then.”
The ongoing dry spell in the state may have also played a role in the die-off, as could the toxic conditions created by the rampant wildfires plaguing the region.
“It can be related to some of the drought conditions,” Desmond said. “It could also be related to the fires in the west.”
“There may have been some damage to these birds in their lungs [due to the fires],” Desmond added.
“They may have been pushed out before they were ready to migrate,” she explained. “They have to put on a certain amount of fat for them to be able to survive the migration. These birds migrate at night and they get up in the jet stream, and they might migrate for three nights in succession, they’ll come down and they’ll feed like crazy, put on more fat and go again.”
In video footage captured on Sept. 13 by journalist Austin Fisher while he was hiking in northern Rio Arriba County, large clusters of dead birds can be seen strewn across the trail.
“I have no idea,” Fisher can be heard saying while he panned the camera to reveal dozens of dead birds lying across the ground.
And as western states have been plunged into an unprecedented deluge of fires across multiple states, reports have emerged of birds disappearing from skies or worse, turning up dead.
Much still remains unknown about how wildfire smoke impacts bird populations, but researchers have noted that birds perpetually live on the edge.
The Oregon Department of Fish and Wildlife recently wrote on Twitter that “not much is known about the impacts of smoke and wildfires on birds.”
However, veterinarians and bird scientists have found that smoke can leave a damaging impact on the lung tissue of captive birds, leaving them susceptible to deadly respiratory infections, reports the Audubon Society. Research has also found that exposure to air pollution causes respiratory distress in birds and increases their susceptibility to respiratory infections.
“We do know that exposure to particulate matter, which of course is of great concern for human health, can affect birds as well,” said Olivia Sanderfoot, a National Science Foundation Graduate Research Fellow at the University of Washington Seattle who studies the impact of air pollution on birds.
Since 1970, bird populations in North America have plummeted by 29 percent, or three billion birds. According to a 2019 study, rampant high temperatures resulting from climate change are drastically altering the migration patterns of bird species. With pastures and grasslands being converted to crops, nesting places have dwindled along with the mass die-offs of insects eliminated by pesticides.
Idaho Senate Approves Bill to Kill 90 Percent of State’s Wolves in “Brutal War”
Idaho’s legislature is swiftly moving forward with a bill that critics say would sanction a “brutal war” on wolves whereby up to 90 percent of the current wolf population would be killed in a bid to protect the interests of the state’s ranchers.
On Wednesday, the Idaho senate passed the measure by a 26-7 vote. The bill will now move forward to the House chamber, reports Associated Press.
Since teetering at the brink of endangerment years ago, wolf populations were removed from the state endangered species list in 2011. Since then, they have thrived despite Idaho allowing hundreds to be killed by hunters, trappers and state measures to control their numbers. Over the past two years, the wolf population has held steady at about 1,500.
According to federal guidelines, wolf recovery numbers require about 150 wolves in the state.
Republican supporters of the bill said during senate debates that the wolf population has grown entirely out of control, endangering the numbers of deer and elk available to hunters and harming the state economy.
“We’re supposed to have 15 packs, 150 wolves. We’re up to 1,553, was the last count, 1,556, something like that. They’re destroying ranchers. They’re destroying wildlife. This is a needed bill,” said Republican state Sen. Mark Harris.
However, critics have blasted the move as rash and potentially damaging to the state’s wildlife.
“The Idaho Senate’s sudden move to pass this bill in the eleventh hour incentivizes the cruel deaths of more than 1,000 wolves across the state,” said Andrea Zaccardi, a senior attorney at the Center for Biological Diversity.
“This brutal war on wolves must be stopped, and we urge the House to deny this bill,” Zaccardi added.
Maggie Howell, the head of the Wolf Conservation Center, also described the move as the latest in a hostile and extreme campaign against wolves that fails to take into account the creatures’ value to the local ecology.
“Beyond the wanton cruelty and devastation the passage of this bill would bring to wolves, this legislation poses a threat to wolves nationwide,” she told the New York Times. “With the Trump administration’s decision to transfer wolf management authority from the federal government to the states, Idaho’s policies can influence expectations about wildlife management beyond its borders.”
As Marine Life Flees the Equator, Global Mass Extinction is Imminent: Scientists
The waters surrounding the equator are one of the most biodiverse areas in the globe, with the tropical area rich in marine life including rare sea turtles, whale sharks, manta rays, and other creatures.
However, rampant rises in temperate have led to a mass exodus of marine species from the sensitive region – with grave implications for life on earth.
While ecologists have long seen the thriving biodiversity of equatorial species holding constant in the past few centuries, a new study by Australian researchers published in The Conversation has found that warming global temperatures are now hitting the equator hard, potentially leading to an unprecedented mass extinction event.
The researchers from the Universities of Auckland, Queensland, and the Sunshine Coast found that as waters surrounding the equator continue to heat up, the ecosystem is being disrupted and forcing species to flee toward the cooler water of the South and North Pole.
The massive changes in marine ecosystems that this entails will have a grave impact not only on ocean life – essentially becoming invasive species in their new homes – but also on the human livelihoods that depend on it.
“When the same thing happened 252 million years ago, 90 percent of all marine species died,” the researchers wrote.
To see where marine life is headed, the researchers tracked the distribution of about 49,000 different species to see what their trajectory was. The global distribution of ocean life typically resembles a bell curve, with far fewer species near the poles and more near the equator.
However, the vast alteration of the curve is already in motion as creatures flee to the poles, according to a study they published in the journal PNAS.
These changes augur major disruptions to global ecosystem as marine life scrambles in a chaotic fight for food, space, and resources – with a mass die-off and extinction of creatures likely resulting.
The research underscores the dire need for human societies to control rampant climate change before the biodiversity and ecological health of the planet is pushed past the point of no return.
Rare Creature Photographed Alive In The Wild For The First Time Ever
Advances in the methods used by researchers to watch wildlife have allowed for the photographing of a rare creature whose image had never been captured in the wild before.
Researchers in the West African nation of Togo were able to spot the rare Walter’s duiker, a rare species of petite African antelope, for the first time in the wild thanks to camera traps equipped with motion sensors.
In addition to the Walter’s duiker, the camera traps were also able to discover rare species of aardvarks and a mongoose, reports Gizmodo.
At a time when the extinction of entire species is becoming more common worldwide, such devices should help conservationists not only preserve creatures sought by bushmeat hunters but also spot rare animals whose presence is elusive for human observers. In the past, biologists were forced to rely on the same hunters for information.
“Camera traps are a game changer when it comes to biodiversity survey fieldwork,” said University of Oxford wildlife biologist Neil D’Cruze.
“I’ve spent weeks roughing it in tropical forests seemingly devoid of any large mammal species,” D’Cruze continued. “Yet when you fire up the laptop and stick in the memory card from camera traps that have been sitting there patiently during the entire trip—and see species that were there with you the entire time —it’s like being given a glimpse into a parallel world.”
The Walter’s duiker was discovered in 2010 when specimens of bushmeat were compared to other duiker specimens. The new images of the creature are the first to have been seen.
Rare species like Walter’s duiker are often not listed as “endangered” by groups like the International Union for Conservation of Nature due to a lack of data.
