In the study conducted by a team of American scientists and published in the scientific journal Plos One, we can see how bald eagles are dying from rat poison. Researchers examined the carcasses of 303 bald eagles that died between 2014 and 2018 and also analyzed the livers of 116 of these specimens and 17 of golden eagles.
They found that rat poison, which poisoning by anticoagulant rodenticide, or the poison used for rodents, was the cause of death for 12 of the eagles being researched. Population of bald eagle has quadrupled in the last decade, many specimens continue to die silently from rat poison, but now experts found traces of rat poison in 82% of eagles they analyzed.
Experts said: "We are unnecessarily killing some of our most majestic bird species. Humans need to understand that when these compounds enter the environment, they cause horrific damage to many species, including our national symbol, the bald eagle.
As people we need to recognize and understand our role in wildlife mortality and adapt our behavior where possible." But also: "Although the exact exposure routes remain unclear, eagles are likely exposed through their predatory activities."
Fires in Australia: billions of wild animals killed
Wildfires in Australia between 2019 and 2020: billions of wild animals was killed according to a latest report. More than 8 million hectares of forest have gone up in smoke.
More than 30 people died and after a series of studies, estimates of damage to fauna were made, published by WWF and entitled Impacts of the unprecedented 2019-2020 bushfires on Australian animals. The researchers involved by the WWF have estimated the potential death of nearly 3 billion native vertebrates for the area burned in the 2019-20 fires.
Estimates of the impact of fires in Australia on reptiles are higher than the other vertebrate taxa considered because reptile densities can be much higher. Some small lizards or skinks can reach and exceed 1,000 individuals per hectare.
Professor Chris Read has estimated that the loss of 240 trillion arthropods killed by the fires can be estimated on the basis of the surface exposed to the fire. Robert Godfree's study published on Nature estimated that seven million hectares of eucalyptus forests and woods and more than 300,000 hectares of rainforest went up in smoke.
More than 800 vascular plant species would have lost more than 50% of their populations and more than 150 native vascular plant species would have suffered fires in 90% of their areas. Species particularly vulnerable to forest fires include epiphytic orchids, which grow on trees, and fire-sensitive rainforest species. In parts of New South Wales, more than three-quarters of rainforest communities have been burned down.
