Blunt-Leaf Waterleaf

The Blunt-Leaf Waterleaf (Hydrophyllum canadense) is a species in the genus Hydrophyllum. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

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.
