Peru: Global Warming brings rare bird to Machu Picchu

The caracara, a bird that usually lives between 3,500 – 5,000 meters (11,482 – 16,404 feet) above sea level, was venerated by the Incas.
Such was the respect the Incas had for the bird that its feathers were used in the headdress if Inca kings.
The Mountain Caracara has recently been found living at much lower altitudes and specialists are asking themselves what has brought the high-Andes bird closer to humans.
According to biologists in Peru, the majestic bird is relocating because of weather alterations and abrupt changes in the climate.
Specialists have noted that more of these birds can be seen at the Inca Citadel atop Machu Picchu, which is 2,400 meters (7,875 ft) above sea level.
Julio Ochoa, a biologist at Machu Picchu Archaeological Park has questioned why the Mountain Caracara (Phalcoboenus megalopterus), a bird that lives 3,500 – 5,000 meters above sea level is seen so frequently at Machu Picchu.
“These are visible consequence of climate change,” said Ochoa.
“Many speak of this phenomenon as if it were something distant. This is a concrete case of the changes that are taking place.”
The ancient Incan sanctuary of Machu Picchu is considered one of humanity’s greatest architectural achievements. Built in a remote Andean setting atop a narrow ridge high above a precipitous river canyon, the site is renowned for its perfect integration with the spectacular landscape. But the sanctuary’s location has long puzzled scientists: Why did the Incas build their masterpiece in such an inaccessible place? Research suggests the answer may be related to the geological faults that lie beneath the site: here.
