How does a darker coloration, like that seen on the Siberian Ibex, benefit the animal on frigid mornings?

Answer

It absorbs more solar radiation, allowing the animal to warm up quickly by basking

Darker coats absorb more solar radiation when the animal basks in the sun, which is a benefit for rapid warming when ambient temperatures are very low in the high altitudes.
