White-necked Jacobin Hummingbird


The White-necked Jacobin hummingbird, a feathered jewel shimmering like a sapphire in flight, might seem like a simple nectar lover at first glance. But beneath its dazzling plumage and seemingly delicate wings lies a treasure trove of surprising facts and adaptations that will transform this tropical acrobat into a captivating aerial dancer, hidden feast master, and unexpected social strategist in your eyes.
