Habitat & Geographic Range

Black-thighed Puffleg

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Distributed across Colombia, Ecuador, and Norway. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Common Cone-headed Grasshopper

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Black-thighed Puffleg

An Andean puffleg hummingbird named for the males' distinctive velvety black thighs contrasting with the characteristic white leg feather puffs, black-thighed pufflegs inhabit humid montane forest and forest edges in Ecuador and Colombia at elevations of 1,500–3,500 meters. Males display glittering green plumage with a violet-blue tail. Listed as Near Threatened due to deforestation of the Andean cloud forest, with populations declining as the specialized high-altitude forest habitat is cleared for agriculture.

Common Cone-headed Grasshopper

<em>Acrida ungarica</em>, commonly known as the common cone-headed grasshopper, is a large grasshopper in the family Acrididae. This species is notable for its distinctively elongated, conical head that gives it a slender, streamlined appearance. It typically inhabits open grasslands, meadows, scrublands, and the margins of wetlands, where tall grasses provide both food and cover. <em>Acrida ungarica</em> is a phytophagous species that feeds primarily on grasses and other herbaceous plants. Its coloration varies from green to brownish-yellow, offering effective camouflage in its grassy habitat. The species is distributed across parts of Europe and western Asia. It is assessed as Least Concern on the IUCN Red List, with no major threats identified to its populations. Biological traits of this species remain poorly documented in the scientific literature.
