Which bird was becoming extinct because its environment was being destroyed?

The passenger pigeon was a bird that became extinct primarily due to habitat destruction and excessive hunting. Once abundant in North America, large-scale deforestation and the expansion of agriculture led to the loss of their nesting habitats. Additionally, commercial hunting in the 19th century decimated their populations, culminating in their extinction in the early 20th century. The passenger pigeon's decline serves as a cautionary tale about the impacts of human activity on wildlife.
