A group of rangers went into the wetland Conaf in Salar de Surire, located at 4,200 meters above sea level and 180 km from Arica, to mark 365 chicks and an adult female flamenco. I carefully installed in a white ring right leg.
This is a signal that associated with this salt, a natural monument since 1983 and Ramsar site (wetland of international importance) since 1996, although they were found in any of the 257 lakes frequented by these birds.
The purpose of banding is to decipher the new migration routes of three species of Andean flamingos being developed to address climate change, a task that the National Forestry Corporation (CONAF) resumed in the Salar del Surire after 14 year break .
wetlands like Surire are spread over the vast area that Andean extends through southern Peru, northern Chile and northwestern Argentina.
The idea is that the work being done in Chile, combined with the specialists engaged in the other three countries with their own markers, revealing the new migration patterns of three species endemic to the area.
These species are the Andean flamingo (Phoenicoparrus andinus), James (P. jamesi) and Chilean (Phoenicopterus chilensis) and are half the species of flamingos in the world.
"Probably, climate change is operating in a different form for each species, as they have no exactly the same requirements, "said the head of Protected Areas of Antofagasta, Nelson Amado.
Newcomers
estimated throughout the Andean region of South America is a Flemish population of 427 000 of the three species. counting them requires a joint effort in the four countries, as these birds migrate through the salt lakes of the area and only sit in certain nesting and resting sites.
The Surire is one of 16 sites priority where they breed. His presence there varies greatly with the seasons: 2,500 copies of the three species in July 28,000 in December.
Surire Amado explains that he became a most important breeding site for the Chilean flamingo, but now have been incorporated significant contingent James flamingo or Puna, which reveals that there are movements in both directions from Chilean Andean lakes to those of Bolivia and Peru.
For its part, the Salar de Atacama, Antofagasta was the largest nesting site for the Andean, but this is starting to choose other areas.
"Maybe some species climate change helps their reproductive success. So we have seen in the chicks born James and Chilean flamingos. Not so well with the Andes, at least in Chile, because you might be finding better conditions in the salt mines of Bolivia and Argentina, "says Amado.
simultaneous censuses since 1997 are underway the four countries show a slight increase in population for the three species whose conservation status is vulnerable. This is good news especially for the Andean flamingo, which discussed the 90 endangered declare.
The downward trend being experienced by Altiplano rainfall and melting glaciers in the high mountains, next to the man exerts pressure on water resources, involve a reduction in water bodies that harbor these species. But Beloved Nelson explained to unravel how this will affect the long term is a pending task. So far, two species have been shown to have a successful reproductive cycle counting with enough mud to build their nests, even in drought cycles.
