Habitat & Geographic Range

American Bald Eagle

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 10 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Europe (8 countries), North America (United States), and South America (Ecuador).

cobweb spiders

Habitat

Typically found in terrestrial habitats from forests to deserts.

Range

Widely distributed across Asia (Japan), Europe (8 countries), North America (United States), and South America (Ecuador).

American Bald Eagle

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

cobweb spiders

The southern black widow (Latrodectus mactans) is one of North America's most recognizable and medically significant spiders, a member of the genus Latrodectus within the family Theridiidae. Females are glossy black with the iconic red hourglass marking on the underside of the abdomen, and reach approximately 8–15 millimeters in body length; males are smaller, paler, and largely harmless. The species constructs irregular, low-lying cobwebs in dark, sheltered locations including woodpiles, outbuildings, hollow logs, rock piles, and debris, where it waits for prey—primarily insects—to blunder into the sticky tangle. Distribution spans the southeastern United States westward through Texas and northward into more temperate zones, with range overlap with related widow species. The venom of Latrodectus mactans contains alpha-latrotoxin, a potent neurotoxin that triggers massive release of neurotransmitters at synaptic junctions, causing the syndrome of latrodectism: severe muscle cramps, pain, hypertension, and autonomic disturbances. Despite its fearsome reputation, bites are rarely fatal in healthy adults when medical treatment is available. Females are cannibalistic toward males, though this behavior is less consistent in nature than laboratory conditions suggest. The species plays an important ecological role in controlling insect populations in arid and semi-arid habitats. Its conservation status has not been formally evaluated by the IUCN.
