* Land use changes: Eagles need large, open areas for nesting and hunting. As human populations grow, these areas are increasingly being converted to other uses such as housing, agriculture, and commercial development.
* Pollution: Eagles can be poisoned by pollutants in the air, water, and soil. These pollutants can come from a variety of sources, including industrial emissions, agricultural runoff, and vehicle exhaust.
* Hunting and persecution: Eagles are sometimes shot or killed for sport or because they are perceived as a threat to livestock or game.
* Habitat fragmentation: Habitat fragmentation occurs when the continuous habitat occupied by a wildlife population is broken into pieces. This can be caused by land development, such as roads and buildings, or natural changes, such as fire. Fragmented habitat can make it more difficult for eagles to travel and find food, and can reduce the quality of their nesting sites.
* Climate change: The warmer and more extreme weather conditions associated with climate change may also threaten the habitat of the bald eagle. rising sea levels may inundate coastal marshes, while increased forest fires and droughts could kill trees and destroy nesting sites.
* Lead poisoning: Bald eagles are also vulnerable to lead poisoning, which can occur from ingesting lead-based ammunition, lead fishing tackle, or lead paint. Lead poisoning can cause a variety of health problems, including brain damage, kidney damage, and death.
* Disease: Eagles are vulnerable to certain types of diseases like West Nile virus, which is spread by mosquitoes and often fatal to eagles.
