The top human causes of bird extinction involve: the increased human population, Climate change, destruction of habitat (through development for habitation, logging, animal and single-crop agriculture, and invasive plants), bird trafficking, egg collecting, pollution (in fertilizers impacting native plants and diversity, pesticides, herbicides directly impacting them as well as the plant and animal food birds eat, including the food for their food source further down along the food chain), and climate change and global warming. Human activity is the greatest cause of bird extinction around the world. According to the American Bird Conservatory, in the Western Hemisphere 12% of bird species are declining at a rate such that they will be extinct within the next century. For example, the wood thrush population in North America has declined 50% in the last 50 years. Some species are not extinct and seem numerous, but exist in highly reduced numbers from previous years. These include countries such as New Zealand, Australia, Fiji, and Papua New Guinea. Historically, the majority of bird extinctions have occurred on islands, particularly those in the Pacific. Since 1500, 150 species of birds have become extinct. There is a general consensus among scientists who study these trends that if human impact on the environment continues as it has, one-third of all bird species and an even greater proportion of bird populations will be gone by the end of this century. Out of the approximately 11,154 known bird species, 159 (1.4%) have become extinct, 226 (2%) are critically endangered, 461 (4.1%) are endangered, 800 (7.2%) are vulnerable and 1,018 (9.1%) are near threatened. Dodos were thought to lay and hatch a single egg at a time each season.Typically human-caused eradication of entire avian species The extinct dodo.The last dodo recorded alive was in 1681.The dodo bird, a relative of the pigeon, was a famous flightless bird that was driven to extinction by humans 175 years after its discovery on the island of Mauritius.Dodos were recorded as being naturally curious, friendly birds.The dodo is mentioned in the book “Alice’s Adventures in Wonderland.”.Until humans discovered the island, the dodo had no natural predators.When we take better care of our forests, mountains and islands, we take better care of the amazing creatures who live there. While we may not ever know all the facts, it’s important to look at creatures like the dodo and apply best practices to the environments and habitats our animal friends live in today. Second, humans also introduced non-native species to the island, which would have introduced new predators or other animal diseases to the dodo. First, humans changed the habitat of the island by cutting down trees or harvesting fruit the dodos liked to eat. So why did the dodo bird go extinct? Scientists say it was likely the result of a combination of reasons.

This heightened smell would have allowed the bird to sniff out and find its favorite food, fruit, in places it could reach from the ground. Scientists have also determined that the dodo had an average sized brain for a bird of that size, with an above-average sense of smell. But scientists say that the dodo’s anatomy actually points to a bird that was quite agile and could move at great speeds. The bird was large-about 3 feet tall-and couldn’t fly. Paleontologists have studied the few physical remains of the dodo left today. These assumptions, however, have been proven false by scientists in recent decades. One of the biggest reasons the dodo hasn’t been erased from memory is that it was often assumed to be so dumb and so ill-adapted to its environment, that extinction was unavoidable. The dodo bird-a bird native to the island of Mauritius in the Indian Ocean–may have gone extinct in the 17 th century, but many are still fascinated by the dodo today.
