Climbing Flat-bean

Climbing Flat Bean, Vigna unguiculata subsp. sesquipedalis, commonly known as the Yard-long Bean or Asparagus Bean, is a vigorous climbing legume in the family Fabaceae widely cultivated across tropical and subtropical Asia for its extraordinarily long, edible pods. The pods, reaching up to 60–100 cm in length, are harvested when young and tender and are used extensively in Chinese, Southeast Asian, and South Asian cuisine. The species climbs trellises and poles using tendril-like, twining stems, producing purplish-white flowers that develop into the characteristic pendulous, slender bean pods. Like other Vigna species, it fixes atmospheric nitrogen through symbiotic bacteria in root nodules, improving soil fertility. Climbing Flat Bean is a warm-season crop requiring full sun, high temperatures, and adequate moisture, making it well suited to humid tropical and monsoon climates. It is an important food crop providing protein and vitamins for rural communities across Asia and is cultivated as a commercial vegetable in many tropical countries. The species is also grown in tropical America and Africa. Being a domesticated cultivar complex, its conservation status is not formally assessed in terms of wild populations, though the preservation of genetic diversity in cultivated landraces is an agricultural priority.

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.
