Definition
Bald eagles are large birds of prey native to North America and known for their white heads and brown bodies. They almost went extinct due to the widespread use of DDT, which caused thinning eggshells and reproductive failures in these birds.
This term refers to species that are at risk of becoming extinct if measures aren't taken for their protection and conservation.
Ecological niche: An ecological niche refers to an organism's role within its habitat, including its interactions with other species and its utilization of resources.
