Hummingbirds are indeed the jewels of the sky! Even Hummingbirds that do not have Hummingbird in their name, like this White-necked Jacobin, a glimmering gem of sapphire and emerald. The Jacobins were the predominant Hummingbirds at our rancho in Costa Rica although many other species made an appearance there. They chased the Mangos and the Mangos chased them. And, they chased all the other hummers that approached the feeders as well. That is until the end of the day when things slowed down just a bit and they seemed to tolerate each others’ presence before nightfall and subsequent torpor.
