There are
few well-studied high-elevation animals. Harsh climate conditions can make it
extremely difficult to conduct field research and observe species in their
natural, alpine habitats. It’s now more important than ever to examine the
changes in habitat and activity in these animals, especially since these
high-altitude regions are being severely impacted by climate change. Without
such knowledge, it is difficult to design conservation strategies to protect
them.
In a
recent study published in the journal Avian Research, Gai Luo and several colleagues from Sichuan
University and the Administration of the Gongga Mountain National Nature
Reserve investigated the distribution of the population of soft-colored, yet
brightly-billed, Tibetan snowcocks. Their objective is to provide both a
baseline to measure the influence of warming on this species and also provide
valuable information on ecology and conservation.
The Tibetan
snowcock is a bird the size of a small chicken and part of the
pheasant family. They can be found all across the Himalayas and the Tibetan
Plateau in high elevations. These birds have red-colored bills and feet and
brown and white stripes along their bodies, which provides camouflage. The
bird’s coloring can make it difficult to spot among the high-altitude rocky
mountain slopes.
According
to the researchers, based on limited descriptions available of this species,
Tibetan snowcocks can be found inhabiting zones exceeding 4,000 meters in the
summer and descending to 3,000 meters during the harsh winters. Breeding season
for these migratory birds begins in mid-May and ends in July. During this
season, snowcocks build shallow nests on the ground lined with dead leaves and
grass, and the monogamous mates remain together throughout the season.
Quantification of snowcock populations is difficult due to the extreme
environments, but some previous research suggests that the Tibetan snowcock
population declined in the 1990s.
Environmental
changes in the previous decades prompted researchers to think about how
glaciers changes and rising temperatures might affect the snowcocks. The
proximity of snowcocks to glaciers raises questions of the role of glaciers and
meltwater on this species. There is currently very little information on the
life history and general ecology of the Tibetan Snowcock, and this information
is essential for potential conservation efforts.
