The brown color variant is the genetically dominant form of plumage in this species

Since the 1980s,climate change has led to significantly less snowfall,but you'd still struggle to spot a tawny owl because nowadays, they're brown.The brown color variant is the genetically dominant form of plumage in this species,but historically,the recessive pale gray variant triumphed because of its selective advantage in helping these predators blend in.However, less snodw cover reduces opportunities for camouflage,so lately, this gray color variant has been losing the battle against natural selection.
