It is difficult, if not impossible, to resist the enchantment produced by a hummingbird. Its graceful figure, dazzling colors, and the fascinating acrobatic ability it can display in front of a flower prevent it. Of the animals that move through the air, the hummingbird is the one that best masters the art of flying: forward, backward, upward, downward. These birds, whose size ranges from 5 to 20 cm, exist only in America, from Alaska to Tierra del Fuego, with the greatest concentration in the tropics. Colombia, Ecuador, and Venezuela have the greatest diversity of hummingbirds, whose family includes more than 100 genera and over 350 species. Specialized in sipping nectar from flowers and incidentally pollinating them, the story of hummingbirds is as magical as their charm, yet still elusive. However, we know that several ancient cultures honored them and left testimony of it. It is enough to recall the hummingbird that appears in one of the Nazca lines. All of this is addressed by the fascinating scientific perspective that this book and its beautiful images offer on the evolution, biology, anatomy, ecology, and other aspects of these ineffable little birds. A perspective as captivating as the object of its study itself. At a time when the planet sees its fauna, flora, waters, climate, and, in general, much of its resources threatened, a book about this extraordinary pollinator, which plays an important role in the conservation of flora, and where we present 100 different species found in Colombia, captured through the lens of the great South African photographer Murray Cooper, is more than timely.
