The red-billed streamertail (''Trochilus polytmus''), also known as the doctor bird, scissor-tail or scissors tail hummingbird, is indigenous to Jamaica, where it is the most abundant and widespread member of the hummingbird family. While most authorities now consider it a separate species, some (including the American Ornithologists' Union) continue to consider it conspecific with the black-billed streamertail. The red-billed streamertail is the national bird of Jamaica.〔(【引用サイトリンク】title=National Symbols of Jamaica )〕 When the black-billed streamertail of eastern Jamaica (found mostly in the parish of Portland) is considered a separate species, the red-billed streamertail occurs west of a line from Morant Bay following the Morant River, and via Ginger House and the middle Rio Grande to Port Antonio. The next-to-outermost rectrices of the male are long, far longer than its bearer's body. Trailing behind the flying hummingbird like thin black streamers, these feathers make a humming sound. Females lack the elongated rectrices, and are largely white below. These birds feed on nectar from flowers using a long extendable tongue or catch small insects on the wing. The bird is featured in Ian Fleming's James Bond short story ''For Your Eyes Only''. The first line of the book reads, "The most beautiful bird in Jamaica, and some say the most beautiful bird in the world, is the streamer-tail or doctor humming-bird." ==Description== The adult male measures 4.5 inches (11.5 cm) without the 'streamers'. With the streamers, it measures 10 inches (25 cm). The crown and tail are black. The feathers at the nape of the neck form tufts. The body is a bright iridescent green. The bill is red with a black tip. The 'black-billed' streamertail is identical in every respect except for the colour of the bill, but is a slightly smaller bird. The female's crown, neck and back are pale green. The lores are pale brown, the wings dark brown, and the tail black with outer feathers tipped with white. The underparts are white. The bill has a dark brown upper mandible and pinkish-brown lower mandible.
