Which subspecies is known for being the most widespread migrant traveling the furthest south?
Answer
The *gambelii* subspecies.
The *gambelii* subspecies is characterized by its strikingly white forehead and typically breeds in the far northern reaches of the continent. Due to its far northern breeding location, this specific form undertakes the most extensive migratory journey, traveling significantly further south into the wintering grounds compared to some of the other coastal or regional subspecies. This extensive movement pattern is partly reflected in its crown pattern, which serves as a field marker distinguishing it from the shorter-distance migrants.
