How does the abundance of Anna's Hummingbird compare in many West Coast areas?
Answer
Anna's is far more abundant and maintains year-round residence in urban areas
When comparing the Costa's Hummingbird to its western neighbors, the Anna's Hummingbird stands out as significantly more widespread and adaptable across the West Coast. The Anna's often maintains year-round residency, including inhabiting many coastal and urban environments where the Costa's is either absent or only a seasonal visitor. This difference highlights the specialized nature of the Costa's, which is locally common only in specific hot, dry niches, whereas the Anna's occupies a much broader spectrum of habitats throughout the year.
