The Giant Hummingbird is the largest species of hummingbird. Indeed, the Giant Hummingbird can be confused on the wing with a swallow or a swift, due both to its large size, and to its peculiar flight, in which short glides often are interspersed among the slow wingbeats. Even when hovering, the Giant Hummingbird has wingbeats that are notably slow for a hummingbird. The plumage generally is cinnamon-brown or cinnamon-rufous, with a conspicuous whitish rump and base to the tail. The Giant Hummingbird is a conspicuous bird, due both to its large size, and because it occurs in open habitats, such as arid montane scrub, and in cultivated areas with hedgerows. The Giant Hummingbird is fairly common, and is one of the most widespread species of hummingbirds in the Andes, occurring from southern Colombia south to Argentina.
