“Being active field ornithologists who are always trying to ID bird species means that one is always faced with the issue of some species being on one list but not the other,” says Çağan Şekercioğlu, associate professor in the School of Biological Sciences. “So our field experience very much primed us to think about this question and inspired us to write this paper.”
The lists have different strengths depending on their application. The BirdLife International list, for example, integrates with the IUCN Red List, which reports on species’ conservation status. The IOC list is updated by experts twice a year, Şekercioğlu says. The list is open access with comparisons to other major lists, and changes are documented transparently.

The mountain forests of Tanzania are more than 9,300 miles away from Salt Lake City, Utah. But, as in eastern Africa, the wild places of Utah depend on a diversity of birds to spread seeds, eat pests and clean up carrion.

So if birds in Tanzania are in trouble in a warming climate, as found in a recent study by University of Utah researchers, people in Utah as well as in the African tropics should pay attention.

In a new study published in
Global Change Biology, doctoral student Monte Neate-Clegg and colleagues tracked the demographics of 21 bird species over 30 years of observations from a mountain forest in Tanzania. For at least six of the species, their population declined over 30 years could be most attributable to rising temperatures an effect of a warming world. Smaller birds, as well as those that live at the lower part of their elevation range, were at higher risk for slowed population growth.
