Great Potoo

Imagine you go at night in a forest, hear the howl of a wolf, a movement nearby and hooting and suddenly scared you turn on a branch and see someone watching you:


Quiet is not a spirit after death, those eyes belong to a animalete, the Great Potoo (Nyctibius grandis).

This bird is a species of night owl. At night spreads its wings proportionately long, and quietly stalks its prey, is dedicated to hunting flying insects: as beetles, crickets, grasshoppers or moths.
But their wings are not the only thing that has large, as other nocturnal owls, their eyes are huge. They are specialized to capture the low light in the darkest environments.

It is found in tropical forests of America .... good find. They are very difficult to see, perhaps for its plumage and nocturnal habits, and in general, they are considered rare. Personally I think so.

Are currently not in danger of extinction. Adults have no predators only eggs are sometimes eaten by howler monkeys and spider monkeys, for some mustelid and large birds of prey.

Kiwi


Kiwi (Apteryx, gr. "Wingless") is a timid animal, a nocturnal bird with a peculiar appearance. The size of a hen, and a highly developed sense of smell, the kiwi has two peculiarities that make it unique in the world.

1 - The first peculiarity is its appearance, in fact, at first thought it was a mammal. Why? Because instead of feathers, has bristles (albeit soft). It has large nostrils in its beak, and has hollow bones like most birds. So the Kiwi is the heaviest bird (in proportion), their legs are strong and running and defend views closely resemble cassowaries ... but that is the second peculiarity.


2 - Evolutionarily speaking, the animal closest to the Kiwi, is the Moa. The Moa is
considered the largest bird that ever lived, in fact, was called "elephant bird" and lived until about 100 years until the man finished with the species.
Instead, the Kiwi is not larger than a hen. But the egg is not that of a hen. It is said that the egg of the Kiwi is huge, bigger than himself ... but of course that's impossible ... but only just ... and is in proportion to the animal body with a large egg

throughout the animal world. In fact, during pregnancy, much of the body size is to accommodate a huge egg. But look at the x-ray.

Indeed, the left image shows the Kiwi again laid the egg. It will have been rested.

The Kiwi living in New Zealand and is in danger of extinction.
