Some animal species, like the leopard, can be found in many kinds of areas. On the other hand, tropical mountain bird species tend to be limited in the types of spaces they can call home. This is because many mountain bird species are only able to survive at very specific elevations. Over time, these species have likely become used to living at a specific temperature. Therefore, these species struggle to survive at elevations that are warmer or colder than they are used to.

A new study reviewed observations of nearly 3,000 bird species to understand why tropical mountain bird species live at specific elevations. They noted that when a mountain bird species was found in an area with many other bird species, it tended to inhabit much smaller geographic areas. It is thus likely that competition for resources with other species, not temperature, limits where these birds can live.
