Gray/Purple Heron

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.

Spirulina rosea is a helically coiled filamentous cyanobacterium distinguished by its pinkish pigmentation, in contrast to the more typical blue-green Spirulina species. It is found in alkaline aquatic habitats and contributes to primary production. Its conservation status is not evaluated.
