The bird population in the US and Canada has fallen by almost three billion since 1970, according to scientists.
Published in the journal Science, the study was carried out by scientists and conservationists from multiple institutions and looked at nearly five decades of population data on 529 species of North American birds. The study shows that populations have declined by an estimated 2.9 billion individuals or 29%.
Ornithologist and lead author Ken Rosenberg, from the Cornell Lab of Ornithology and American Bird Conservancy, admitted that scientists knew some bird populations were on the decline but the sheer number of losses were ‘stunning’.
Speaking to IFLScience, he said:
We thought that increases in other species would balance everything out overall. That’s not the case at all.
The research found the amount of birds present at the start of the breeding season has fallen from just over 10 billion to little more than seven billion in the last 50 years, meaning the US and Canada have lost more than one in four birds.
Grassland species like Western Meadowlarks and American Sparrows have been hit the hardest with more than 715 million birds disappearing since 1970. Shorebirds such as green herons have had one-third of their population numbers wiped.
According to the Cornell Chronicle, Rosenberg commented on what the results may mean, saying:
It’s a strong signal that our human-altered landscapes are losing their ability to support birdlife. And that is an indicator of a coming collapse of the overall environment.
The bulk of the losses haven’t been rare species, but rather common birds. A dozen bird families, including finches, warblers and blackbirds, accounted for 90 per cent of the total loss, according to IFLScience.
Pete Marra, an ecologist who worked on the study, spoke to NBC News about the findings.
He explained:
We can all talk through the stories about there being fewer and fewer birds, but it’s not until you really put the numbers on it that you can really grasp the magnitude of these results.
We’re now seeing common species that have declined, things like red-winged blackbirds and grackles and meadowlarks — species that I grew up with, that were very common when I was a kid. That is the most surprising and most disturbing part.
It’s an empty feeling in your stomach that these same birds that you grew up with just aren’t there anymore.
President of the American Bird Conservancy and a co-author of the study, Mike Parr, described the findings as an ‘indication that nature is unravelling and that ecosystems are highly stressed’.
Researchers say humans are the driving force behind the decline through the clearing of land, widespread pesticide use and by allowing domestic cats to roam outdoors.
Along with the negative data, there was some positive findings; Waterfowl numbers have grown over the last 50 years thanks to policies such as the 1972 Clean Water Act which have helped conserve wetlands. Bald eagles also thrived after DDT pesticides were banned and legislation was passed to help protect them.
Dr. Rosenberg says he is ‘hopeful’ that bird populations will bounce back but there needs to be changes made in order for them to do so.
The researchers agreed lawmakers could help by enacting legislation to conserve federal lands and stop the use of neonicotinoid insecticides, while members of the public can help by keeping pet cats indoors and eating organic food to help reduce the use of pesticides.

Orange Sahara Dust Cloud Descends Over Athens
Orange Dust Haze Over Athens: The Sahara's Impact and What Lies Ahead
As Athenians woke up to an otherworldly scene, a striking orange haze enveloped the cityscape, an eerie reminder of nature's untamed forces. This isn't the first time the skies over Greece have turned shades of Martian orange, but the recent Sahara dust event is among the most severe since 2018.
This phenomenon, resulting from vast clouds of mineral dust carried from the Sahara Desert, casts a surreal glow and a thick blanket over Athens, extending as far north as Thessaloniki.
A Persistent and Expansive Issue. The Sahara Desert, an immense landscape of arid expanses, annually releases between 60 to 200 million tonnes of mineral dust into the atmosphere. While much of this dust settles back to the earth's surface relatively quickly, finer particles are swept across continents by upper-level winds.
In this instance, the dust not only shrouded Greece but also affected regions as disparate as Switzerland and southern France in late March and early April. This wide-reaching impact highlights the interconnectedness of environmental phenomena, transcending geographical boundaries.
Atmospheric Conditions and Public Health
The mingling of dust with unusually high temperatures has created stifling conditions in southern Greece. Kostas Lagouvardos, a noted meteorologist, likened the view from a local weather station to the surface of Mars, emphasizing the dramatic alteration in the landscape and atmosphere. The compromised air quality poses significant health risks, particularly for those with respiratory ailments. Greek authorities have advised the public to wear protective masks, limit outdoor activities, and postpone physical exercise until the air clears—a temporary but vital adaptation to the hazardous conditions.
Complicating the environmental challenge are the wildfires that have flared up concurrently. In the past 24 hours alone, the Greek fire service has battled 25 wildfires. One particularly fierce blaze near a naval base on Crete necessitated the evacuation of homes and a kindergarten as temperatures on the island soared above 30°C (86°F). This confluence of dust, heat, and fire underscores the broader climatic vulnerabilities that Greece, like many parts of the world, faces amid changing global weather patterns.
Looking Ahead: Environmental Implications and Actions
The recurring dust episodes and their intensification call for a reevaluation of environmental and health preparedness strategies. Enhancing predictive meteorological models and public health advisories can play pivotal roles in mitigating the impacts of such dust storms. Moreover, understanding the broader implications of these dust clouds on climate change, soil deposition, and even marine ecosystems will be crucial.
As we contemplate the orange haze that temporarily transforms day into dusk, it serves as a vivid, visual reminder of our planet's dynamic and interconnected environmental systems.
The need for increased research, international cooperation, and proactive measures has never been more apparent, ensuring that societies can better anticipate, respond to, and ultimately thrive amidst these challenges. The dust will settle, but the conversation and actions it precipitates must continue to evolve.
‘Whale Bones’ Capturer Earns Underwater Photographer Of The Year

Deforestation Forces Animals To Eat Infected Bat Poo in Uganda
The Unseen Dangers of Deforestation: A Deep Dive into Uganda's Bat Poo Crisis
In the dense canopy of Uganda's Budongo Forest, a strange and potentially dangerous new food source has emerged for the local wildlife: bat guano.
This phenomenon has come about not through natural evolution but as a dire consequence of human activity—specifically, tobacco farming, which has led to a severe depletion of the native flora.
The ramifications of this change are profound, shedding light on the complex interplay between deforestation and emerging infectious diseases.
The Unintended Consequences of Agricultural Practices
Over the last six years, a collaborative research project between the University of Stirling and the University of Wisconsin-Madison has unveiled startling findings about the diet of local wildlife, including chimpanzees, antelopes, and monkeys. Dr. Pawel Fedurek from the Faculty of Natural Sciences at the University of Stirling first observed these animals consuming bat guano, a substance rich in viruses, some of which are related to the infamous SARS-CoV-2.
The guano serves as an "alternative source of crucial minerals" for the animals, according to the study published in the prestigious Nature journal. This shift in dietary source is a direct result of the local palm trees being "harvested to extinction" to facilitate the drying of tobacco leaves, which are then sold to international markets.
The environmental impact of this agricultural practice extends beyond deforestation: it has created a pathway for potential zoonotic virus transmission, highlighting a subtle but devastating aspect of selective deforestation driven by global tobacco demand.
Viral Pathogens: A Hidden Threat in the Forest
Lab analysis of the collected guano revealed 27 viruses, all previously unknown to science, underscoring the vast unknowns that lie within wildlife and their interactions with pathogens.
Prof. Tony Goldberg from the University of Wisconsin-Madison pointed out the novelty of these viruses and the potential dangers they could pose to humans and other animals. "All 27 viruses were new to science," he explained, "so we don't know what effects they might have on humans or other animals. But one virus stood out because it was a relative of a virus everyone knows: SARS coronavirus 2."
The study provides a critical example of how new infections might jump species barriers, a scenario that has become all too familiar with the recent COVID-19 pandemic. The potential for similar future outbreaks is real and alarming.
As Dr. Fedurek noted,
"Our research illustrates how a subtle form of selective deforestation ultimately driven by a global demand for tobacco can expose wildlife, and by extension humans, to viruses residing in bat guano, increasing virus spillover risk."
This research not only raises awareness about the unintended consequences of agricultural practices but also stresses the urgent need for interventions to prevent future pandemics. By understanding the triggers and pathways of virus transmission from wildlife to humans, researchers hope to improve our ability to foresee and mitigate the risks of emerging diseases.
The Budongo case study is a stark reminder of the interconnectedness of our environmental, economic, and health systems. It underscores the need for a more sustainable approach to agriculture and land use that considers the long-term health of both the planet and its inhabitants.
As we continue to encroach on natural habitats, the line between wildlife and human disease reservoirs becomes increasingly blurred, necessitating a re-evaluation of our impact on the world around us.
Potential ‘Largest Reptile Ever’ Discovered On Family Beach Day
Prehistoric Leviathan: Family's Beach Day Leads to Monumental Ichthyosaur Discovery
The serene shores of Somerset, England, are once again at the center of a paleontological breakthrough. A jaw-dropping find—a jawbone over two meters long, belonging to a previously unknown species of ichthyosaur—has the scientific community buzzing with excitement.
Dubbed Ichthyotitan severnensis or "giant fish lizard of the Severn," this marine behemoth is estimated to have been as colossal as a blue whale, stretching over 25 meters long.
A Family Affair: Discovery by Chance
The tale of this remarkable discovery begins with a family outing that turned into a scientific expedition. Ruby Reynolds, a sharp-eyed 11-year-old, and her father, Justin, stumbled upon the first fragments of the giant bone while fossil hunting on the beach at Blue Anchor in May 2020.
Recognizing the significance of their find, they contacted Dr. Dean Lomax, a leading ichthyosaur expert from the University of Bristol. Dr. Lomax, in turn, reached out to Paul de la Salle, who had discovered a similar giant jawbone in 2016.
Together, they unearthed additional pieces, assembling a prehistoric puzzle that would lead to the identification of a new species.
The Significance of the Find
This discovery is not just about adding a new species to the scientific records; it challenges our understanding of marine life in the Triassic period.
The jawbones of Ichthyotitan provide hard evidence of giant ichthyosaurs swimming in the prehistoric oceans about 202 million years ago, just before a global mass extinction event wiped them from existence.
These giants roamed the seas at a time when dinosaurs were beginning to dominate the land, painting a picture of a world vastly different from our own.
The Science Behind the Bones
The research team, which includes experts from the University of Bristol and the University of Bonn, has employed advanced techniques to analyze the fossils.
Marcello Perillo, a master’s student involved in the study, took core samples that confirmed the ichthyosaur origin of the bones and suggested that the creature was still growing at the time of its death.
This hints at unknown biological strategies that may have allowed these giant creatures to reach such massive sizes.
A Community Effort
The discovery of Ichthyotitan severnensis has been a community effort, highlighting the importance of amateur fossil hunters in the field of paleontology. Ruby Reynolds, now a published young scientist, expressed her excitement and pride in contributing to such a significant scientific discovery.
Her story is reminiscent of Mary Anning, the famous fossil collector who made numerous significant contributions to paleontology in the 19th century.
Exhibiting History
The bones of Ichthyotitan are set to be displayed at the Bristol Museum and Art Gallery, bringing the story of these magnificent creatures to the public.
This exhibition will not only showcase the jawbones but also feature scaled 3D replicas, created by Jimmy Waldron of the DWABA museum in Orlando, Florida, allowing people around the world to marvel at the size and scale of these prehistoric giants.
Reflections on a Giant
The story of Ichthyotitan severnensis is more than a tale of discovery. It is a testament to the enduring curiosity of humans, the thrill of discovery, and the never-ending quest to understand our planet's ancient past.
As these giants once dominated the seas, their fossils now beckon us to explore and appreciate the complex history of life on Earth.
It reminds us that each fossil holds a story, a glimpse into an era where the world was a vastly different place, encouraging us to keep looking, learning, and wondering about the great unknown.
Volcano Erupts In Indonesia: More Than 11,000 Evacuated
Rising from the Depths: The Volcanic Agitation of Mount Ruang
In the quiet darkness of a Tuesday night in North Sulawesi Province, Indonesia, the earth reminded everyone of its fiery core as Mount Ruang erupted, catapulting ash and smoke over two kilometers into the sky.
This dramatic spectacle marked the beginning of a series of eruptions that would see more than 11,000 residents hastily evacuating under the cloak of uncertainty and ash.
The Awakening Giant
Mount Ruang, a 725-meter colossus, is no stranger to the limelight, having etched its power in the history books with a catastrophic eruption in 1871 that triggered a tsunami. This week’s activity began at 9:45 PM local time, with the volcano asserting its might in a display that lit up the night sky with billowing smoke and cascading lava flows that painted the dark waters a glowing red.
Local authorities, quick to respond, escalated the alert level to four—the highest possible—while expanding the exclusion zone from four kilometers to six. Abdul Muhari, head of the disaster agency’s data communications and information centre, underscored the urgency of the situation, noting that everyone within this newly defined danger zone had to move to safer grounds immediately.
A Community on the Move
The initial exodus saw over 800 individuals relocate to Tagulandang Island, with subsequent eruptions necessitating further evacuations to the provincial capital, Manado.
The logistics of moving thousands in the face of an ongoing natural disaster are daunting. Yet, the community's resilience and the coordinated efforts of local authorities have painted a picture of determination and solidarity.
The Broader Impact
The eruptions have not only disrupted lives but also air travel. The spread of volcanic ash led to the temporary closure of Sam Ratulangi International Airport, a crucial hub with links to China, Singapore, and South Korea. Flights from Kota Kinabalu International Airport in Malaysia also faced significant disruptions, emphasizing the far-reaching impacts of such natural events.
Important Travel Update:
— Malaysia Airlines (@MAS) April 18, 2024
Malaysia Airlines has suspended several flights to/from KL International Airport (KUL) to Sabah and Sarawak today, 18 April 2024 due to the volcanic eruption at Mount Ruang, Indonesia.
Our priority is your safety. We're closely monitoring the situation…
A Geological Hotspot
Indonesia's geographic positioning on the 'Ring of Fire'—a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur—makes it a hotspot for seismic and volcanic activity. The country hosts 120 active volcanoes, and the memory of the 2018 Anak Krakatoa eruption, which claimed hundreds of lives, is still fresh.
Reflecting on Nature’s Might
The ongoing situation at Mount Ruang is a stark reminder of the dynamic and sometimes perilous nature of our planet. As scientists and authorities work to monitor and respond to these geological events, the resilience of the affected communities continues to be tested. The eruptions serve as both a spectacle of nature’s raw beauty and a call to respect and prepare for its potential fury.
In the face of such overwhelming natural power, the spirit of the people in North Sulawesi is a testament to human resilience. The coming days will undoubtedly be challenging, but also a chance for collective learning and adaptation in the shadow of one of nature’s most awe-inspiring phenomena.
