Sword-billed Hummingbird.

In every ecosystem there are different relationships between living creatures, from bacteria to the top predator that sits on top of the trophic chain. When, for whatever reason, a species is extirpated, endangered the interaction of all individuals in the ecosystem.

But not all species are just as essential, and although all have a role, there are some that are more importances others. The case of Sword-billed Hummingbird is a clear example of a species must.

The main feature of Sword-billed hummingbird (Ensifera ensifera) is that it has the longer beak, in which all the birds in the world, in relation to the body. The peak measured the same as the length of the body that has such a long beak, it is no casuality.

As we know, generally hummingbirds feed on a product superenergy, the nectar of flowers. They have to enter the peak inside the flower for be done with the nectar, while the pollen of flowers were deposited on their heads to when a new flower pollinate.

Well, some flowers have been very demanding of their pollinators, needed a pollinator (a hummingbird in this case), to eat the nectar while pollen is impregnated. The easiest way was to extend the floral pendulum: if the hummingbird enters the head from inside the flower to get the nectar, their pollen impregnate feathers, enter the peak itself, is more difficult to impregnate. As they were stretching peaks hummingbirds also lengthened the pendulums of flowers. This, over the centuries, caused very long peaks as the sword-billed hummingbird and floral tubes also very long.

These specialized flowers, we can find Passiflora Datura or Passiflora mixta. These are elongated flowering plants so that only the Sword-billed Hummingbird can ponilizar the fact, it is believed that if the Sword-billed Hummingbird disappeared, also these plants poof and disappear ... specialization may be the cause of its demise. Although thankfully, we are certain that the Sword-billed Hummingbird is not endangered .... Some plants chose well to its pollinator.
