Habitat & Geographic Range

Common Oak

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Africa (Lesotho, South Africa), Asia (Armenia, India), Europe (8 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (4 countries).

Scarlet Macaw

Habitat

Typically found in grasslands, forests, and vegetated habitats.

Range

Found across Europe (5 countries) and South America (Colombia, Ecuador, Venezuela). Population trends indicate a declining trajectory in parts of its range.

Common Oak

One of Europe's most important and widespread deciduous trees, the pedunculate oak can live over 1,000 years, reach 40 meters, and support the greatest biodiversity of any European tree species — over 2,300 species of insects, fungi, lichens, mosses, and birds directly depend on mature oaks. Found across Europe to western Asia in temperate forests, its hard, durable wood has been foundational to shipbuilding, architecture, and barrel making throughout history.

Scarlet Macaw

One of the most brilliantly colored birds in the Americas, scarlet macaws display vivid red, yellow, and blue plumage with wingspans reaching 1 meter. Found in humid lowland forests from Mexico to Bolivia, they are highly intelligent, long-lived — up to 75 years — and form lifelong pair bonds. They travel long distances to clay licks where they consume mineral-rich soil to detoxify seeds. Listed as Least Concern but locally threatened by habitat loss and the pet trade.
