However, there are a few things that can threaten them:
* Larger birds of prey: While they won't actively hunt frigatebirds, large birds like eagles or hawks could potentially prey on chicks or weakened individuals.
* Humans: Human activity, including habitat loss, pollution, and fishing bycatch, can pose a threat to frigatebird populations.
* Parasites: Frigatebirds can be affected by various parasites like mites, lice, and intestinal worms.
* Storms and weather: Extreme weather events can lead to injury or death.
Overall, frigatebirds are very well-adapted to their environment and have few natural predators. Their main threats come from human activity and the occasional opportunistic predator.
