The world’s tiniest bird, the bee hummingbird, measures a mere 5.5 cm (for males; females are slightly larger at around 6.1 cm). These delicate creatures, weighing only 1.95 grams, can be found exclusively in Cuba. They sip nectar from flowers and often mistaken for buzzing bees, hence their name.

The Esmeraldas Woodstar, a rare neotropical hummingbird, belongs to a group of six smaller species. They are among the tiniest birds, with males sporting a vibrant purple throat. These birds inhabit the Pacific coast of western Ecuador, thriving in forests and feeding on nectar. Sadly, deforestation poses a significant threat to them, making them a vulnerable species in need of habitat protector.

Its name, Calliope, comes from the Greek muse and its previous genus name means “little star.”
