Humans have had a profound effect on many bird species. Over one hundred species have gone extinct in historical times, although the most dramatic human-caused extinctions occurred in the Pacific Ocean as humans colonised the islands of Melanesia, Polynesia and Micronesia, during which an estimated 750–1,800 species of birds became extinct.

Climate change has raised the temperature of the Earth by about 1.1 °C (2.0 °F) since the Industrial Revolution.As the extent of future greenhouse gas emissions and mitigation actions determines the climate change scenario taken, warming may increase from present levels by less than 0.4 °C (0.72 °F) with rapid and comprehensive mitigation (the 1.5 °C (2.7 °F) Paris Agreement goal) to ...
Whatever your views on outdoor cats, it’s unavoidable that indoor cats are safer to birds – a study from 2013 found that domestic cats kill billions of birds and mammals each year.
McCulloch says people can keep cats indoors, turn off lights at night, and put decal stickers or paint patterns on windows to help keep birds safe. Markings should be close together – about two ...
Extinction can be caused due to non-native species being introduced that become invasive. An example of how this may happen is through by-catch.These new species will outcompete the native species and take over, therefore causing the local or global extinction of a species.
Cats that spend time outdoors are at greater risk with exposure from dead animals, as well as wild birds or mice, which can also carry bird flu. Bailey and Coleman recommend trying to reduce their ...
The Bramble Cay melomys, thought to be the first mammal species to go extinct due to the impacts of climate change [9] A 2013 paper looked at 12 900 islands in the Pacific Ocean and Southeast Asia which host over 3000 vertebrates, and how they would be affected by sea level rise of 1, 3 and 6 meters (with the last two levels not anticipated ...
Lyall's wren became extinct within two years of the introduction of cats to Stephens Island. Many islands host ecologically naive animal species. That is, animals that do not have predator responses for dealing with predators such as cats. [8] Pet cats introduced to such islands have had a devastating impact on these islands' biodiversity. [9]
