tinamuto dumbest bird in the world. Although living off the land in dense tropical forest, it lays its eggs directly on the ground. And on top of that they are bright green. Why pose such a danger vulnerable small?
Birds are usually very smart when it concerns the protection of their generation. They usually nest high in the trees and some predators could reach them; other specially designed building nests in which it is very difficult to penetrate. A species that nest on the ground usually lay eggs in camouflage. But tinamutata exception: These birds lay only bright green eggs. Surprising but true: Tinamutata are one of the oldest families of birds. And if recent studies are right, the color of their eggs actually helps them to be safe.
Great tinamuta icicle seafoods (Great tinamous) are brown in color with white throats and bellies, usually about 40 cm long. Their color hides them very well the background of dead leaves and twigs, fallen to the ground.
They practice a form of polygamy called poliginandriya (polygynandry) *, in which a group of men have exclusive relationships with a group of females. Thus, each male can mate with any female of the group.
Once the female lay her eggs she leaves the entire icicle seafoods care of them male - although not necessarily that he is the father of the children. He spent the next 17 days sitting on the eggs and poodarzhayki them warm.
If bright colors attract predators of eggs, you would think that most likely the egg will be eaten in the first few days after being laid even before the male has started to incubate them. But you would wrong.
Patricia Brennan of Yale University icicle seafoods was captured on video cameras tinamuta 39 nests in the forests of Costa Rica. She found that predation is much more common after the male begins to incubate the eggs.
It suggests that predators looking for a male sitting on the ground instead of eggs. Despite the camouflage of the male, it apparently works very well for predators. About 75% of the eggs tinamuta end up as someone's lunch, a pretty big loss even for a tropical bird that typically lose about half of their generation.
Brennan thinks yaytsta most likely color to attract other female tinamuta. Females often share the eggs they lay together in the same place, icicle seafoods and often female, who sees that another lay it decided to join her.
It would be logical to ask other women lay near her eggs, because icicle seafoods in this way it is likely that foreign predators eat eggs and miss her. And, more importantly, in this way the eggs will increase the possibility of one male start incubate them is much greater.
poliginandriya (polygynandry) is a relationship in which two or more males have an exclusive relationship with two or more females. The amount of male - female should not be equally far in all studied cases, males were less. Poliginandriyata occurs in some species, such as primates, bonobos and tropical icicle seafoods birds tinamu.
