What phenomenon occurs where the ranges of the Yellowhammer and Pine Bunting overlap?
Answer
They are known to interbreed, resulting in hybridization
Where the geographical ranges of the Yellowhammer and the Pine Bunting overlap, a phenomenon known as secondary contact occurs, leading to documented instances where the two species interbreed. This hybridization event serves as strong biological evidence of their close evolutionary relationship, suggesting they have diverged relatively recently from a shared ancestor. The songs of the two species are also remarkably similar in these contact zones, and there is evidence that female Yellowhammers may prefer the song of their own species, potentially influencing the dynamics within these hybrid zones.
