As the species on top of the food chain, the Philippine Eagle has a crucial role to play in keeping the gentle balance of the ecosystem in check. It helps naturally regulate species population and provide an umbrella of protection to all other life forms in its territory. An abundant Philippine Eagle population means signifies a healthy forest.

Greater Honeyguides live up to their name and range throughout sub-Saharan Africa: There, the brown-and-cream-colored birds, which eat bees wax and insect larvae, literally guide people to honey. Northern eagles are migratory,while southern birds are resident, remaining on their breeding territory all year. Continuing threats to bald eagle populations include lead poisoning from ammunition in hunter-shot prey, collisions with motor vehicles and stationary structures, and development-related destruction of shoreline nesting, perching, roosting and foraging habitats. Based upon information of population trends, the IUCN Red List of Threatened Species has listed the bald eagle a species of Least Concern and current data demonstrates that the population is presently increasing. While unfortunate, eagle losses at modern wind farms are a rare and random event, with only a few bald eagles having ever been observed to have died in collisions with a wind turbine. Range In Channel Islands National Park, due to the persecution by humans and the effects of organochlorine chemicals such as DDT, breeding bald eagles were eliminated by the mid-1950's. They do this by killing weak, old, and slower animals, leaving only the healthiest to survive.

Barn Swallows aren't just good news for farmers. The largest bald eagle nest on record, in St. Petersburg, Florida, was 10 feet in diameter and 20 feet tall. As such, this species plays a key role in biodiversity functions across vast landscapes and is generally considered an indicator of ecosystem health ( Katzner et al., 2020 ).
