Allotrie intermédiaire

The Clicking Shrike-babbler, Pteruthius intermedius, is a small, chunky passerine bird in the family Vireonidae found in the montane forests of Southeast Asia and the eastern Himalayas, ranging from northeastern India and Bhutan through Myanmar, northern Thailand, Laos, Vietnam, and southern China. The species inhabits subtropical and temperate broadleaf montane forests at elevations generally between 1,500 and 3,000 meters, where it forages actively in the forest canopy and mid-story for insects, larvae, and small berries. Males display striking plumage with a gray head, rufous flanks, and a white wing patch, while females are more cryptically colored in olive and buff. The name 'clicking' refers to the species' characteristic vocalizations, including sharp clicking and chattering calls used in territorial defense and pair communication. Pteruthius intermedius is typically encountered in pairs or small groups and regularly joins mixed-species bird flocks that forage through the forest interior, a common foraging strategy in diverse Asian montane bird communities. Montane forest birds of Southeast Asia face increasing pressure from deforestation, agricultural encroachment at forest margins, and climate-driven upslope habitat contraction. The species is currently assessed as Least Concern by IUCN.

ours blanc

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
