"Survival of the fantastic" involves whatever appeals to the opposite sex, no matter how energy-consuming, attention-drawing, or otherwise negative, in order to pass one's genes to the next generation.
"Survival of the fantastic" involves whatever appeals to the opposite sex, no matter how energy-consuming, attention-drawing, or otherwise negative, in order to pass one's genes to the next generation. This is carried to extremes in several groups of birds, including a group of tiny birds from the forests of Central and South America, called the manakins.
Many of the sixty or so species perform bizarre displays, with surprising sound effects, featuring the brilliant colors and unusual shapes of their feathers. The Dallas World Aquarium's new "Jungle Jewels" was designed to showcase these marvelous birds, and five species can be enjoyed in the exhibit. Except for the Golden-headed manakin, which can be found in several zoos, these are the only specimens which can be seen in North America. The Dallas World Aquarium was able to import them through special permission from the government of Panama.
The Red-capped and Golden-headed manakin males have black bodies and startling white eyes, differing in their respective head colors. (The females of most manakins are difficult to tell apart, being round and grayish-green). These two species have similar displays, where the male lifts his wings and zips back and forth on a twig, moving his feet incredibly fast. Videos of the "Moon Walk" bird are popular web-junk. That species is the Red-capped manakin.
The male Golden-collared manakin performs an entirely different courtship display. While making startling snapping sounds with his wings, he darts around, with the feathers under his beak bunched together like a pointing finger, parallel with his beak.
One male Lance-tailed manakin is not yet in full adult plumage. He has a bright red cap, but he does not have a shiny blue back yet. The males of this species perform their display in teams of two, jumping up and down, side by side, on a branch, while snarling and whistling.
Our male Blue-crowned manakin performs a quieter display, bowing his brilliantly colored head forward while giving a musical trill.
While our manakins have only been at The Dallas World Aquarium a few months, some of these displays are performed fairly often.
Several other small jewel-like birds share this exhibit. These are tanagers, members of a large New World group. The four species seen here are the Golden-crowned chorophonia, the Speckled, Silver-throated and Paradise tanagers. While the male and female chlorophonias are colored differently, the other three share the same brilliant colors in both sexes.
Three larger birds that also live here are:
- The shiny green and red Black-tailed trogons from South America are relatives of the famous Quetzal.
- The Wattled jacanas are from South America, but have relatives which occur just over the Mexican border into Texas, in the Rio Grande Valley. These shorebirds have amazingly long toes with which they can walk on floating plants. They also have sharp spurs at the bend of the wing.
- The earth-toned Chirqui quail doves are found only in the mountains of Panama and Costa Rica. As one would gather from their name, these plump birds spend most of their time on the ground, though they roost on branches at night.
