Upper Temperate Forest

Caption

The researchers found that competition set the boundaries for a mere 12 percent of Himalayan bird species, while temperature and habitat dictate where 48 and 40 percent of species live, respectively. Pictured above are a chestnut-headed tesia (Oligura castaneocoronata) (left), a species limited by temperature, and a collared grosbeak (Mycerobas affinis) (right), a species limited by habitat. Both species live in upper temperate forests (center).
