Hummingbirds have always held popular appeal, with their visual brilliance, extraordinary flight dexterity, and jewel-like size and colour. But it is almost as if their beauty has blinded us to their importance. Only recently has their serious scientific study started to gain the attention it demands. With the increasing interest in biodiversity, and the hummingbird's position as the second most diverse bird group after flycatchers, they are a subject growing in significance with each new species discovery. Hummingbirds presents every species, arranged taxonomically, with over 300 birds shown in dazzling, life-size, cut-out photography. Concise descriptions, written by two of the worlds leading experts, are digitally enhanced through QR-code links to movie footage of flight, sound, and behaviour. Presented in a compact format adorned with sprayed page edges, do not allow its miniature beauty to blind you to its significance.
