Birding across South America

September 27, 2015 by Michael

On August 28^th 2015 Paula and I returned to South America from the UK. The Andean Wildlife Project resumes and our objective from now on will be more ornithological and in particular to understand why there are so many bird species on this incredible continent.

Where best to start this quest than to head for one of the most avian rich countries in the world, Peru. To get there we needed to drive right across Argentina, traverse the Andes mountains and then up through the Atacama desert in Chile and finally to cross the border of Peru at Arica. Birding across South America.

We left Buenos Aires and headed north following the flat marshlands of the Parana river. This massive series of wetlands is now much reduced, replaced instead by cattle ranching country. Nevertheless a variety of Egrets, Ibis, Wood Rails and Snail Kites abounded.

Moving east we entered the Chaco ecoregion. We found that much of the land was degraded and much used as cattle pasture. Eventually we found a series of sand tracks that penetrated the almost impenetrable thorny scrub, interspersed with candelabra cacti and small low growing acacia type trees. In this area we found Black-crested Finch, Golden-billed Saltators , Duica Finches and Monk Parakeets.

The journey northwards from Cordoba to Tucuman took us into an altogether richer agricultural area, where great machines were harvesting the sugar cane. Picui ground doves swarmed over the plantations and Guira Cuckoos, usually in small groups, were common. To our west we saw tantalising glimpses of the Andean foothills and longed to reach those verdant valleys where we had spent so many happy hours earlier in the year. The nearer we got to Tucuman so the Lemon groves increased, trucks piled high with the fruit vied with the even larger trucks carrying sugar cane.

We spent a day with our good friends in Tucuman and also had some necessary minor repairs done to the vehicle, putting new rivets in the steps, which had vibrated out on the poor roads.

Still further north of Salta, passing alongside the transitional forests on the foothills, White-tailed and Roadside hawks were regularly perched on the larger trees and high above circled Turkey Vultures and the occasional Aguila mora. We passed the turnoff to El Rey National Park; a place we had not visited and wanted to in the future, but our destination in deepest, darkest Peru remained a long way off, we needed to press on.

On Tuesday September 1^st we started our climb into the high Andes, into the beautiful Puna ecoregion where stipa grasses dominated and the few small wetlands held resident Crested Ducks.

We reached the Jama Pass in the late afternoon only to find the border closed. We spent a fitful night’s sleep in the freezing cold and at an uncomfortable altitude of 4500m.

Crossing the border the next day we climbed even higher onto the Chilean altiplano, an arrestingly stark and barren environment.

We dropped down the western slope of the Andes into San Pedro de Atacama and continued onwards across the Atacama desert and eventually to the Chilean coast at Paposo. We had visited this area eight months prior and were interested to find if the heavy rains that had occurred after we left had led to a rare flowering of the coastal desert. There were many small shrubs that were in flower and certainly everything was much greener, but the spectacular flowering of the bulbous plants had not yet started.

We camped on the shore and were surprised by the number of Snowy Plovers and Seaside Cinclodes.

Spending more time on the beautiful Chilean coast would have to wait for another time, we had to move on .

It took two more days driving north through the endless Atacama desert to reach Arica in the very far north of Chile, the gateway to Peru and the goal of this journey, the famed lush sub-tropical forests of the eastern slope of the Andes.

Wildlife in the Atacama

April 12, 2015 by Michael

Paula and I have just spent several weeks in the Atacama desert searching for wildlife. It’s the driest place on earth but there are areas where nature provides enough moisture for a wide variety of life to survive.

The Atacama is a huge area and we found that two factors were key as to where animals and plants thrived, firstly the proximity to the coast and secondly the altitude.

In the west the Atacama starts right on the Pacific seashore, extending across a narrow coastal plain and then up and over a narrow range of mountains about 50 miles wide. This is the coastal desert and stretches about 600 miles from north to south.

The prevailing wind blowing from the ocean moves clouds of fog over the coastal plain and then up and over the mountains, enveloping the plants in moisture. This bountiful fog is locally called the ‘Camanchaca‘.

Cacti are the predominant family of plants that have adapted to this.

There are a few special areas in this Coastal Desert where cacti thrive exceptionally well , such places are called ‘fog meadows’ and we found such an area near the Llanos de Challe National Park, where there were hillsides covered in cacti particularly of the Copiapoa family.

Paula and I spent some glorious days in these ‘fog meadows’ photographing these amazing plants but always being very carful when we bent down !

A common reptile of the ‘fog meadows’ was the Lava lizard.

To the east of the coastal range of mountains the temperatures soar. This part of the Atacama is called the ‘absolute desert’, probably because there is absolutely nothing there and not surprisingly our search for wildlife was almost fruitless.

Several hours in the relentless heat was enough for us. We could find no living things at all, except in the hazy sky above, where a Mountain Caracara flew.

The plains of the absolute desert range between 3,500 ft – 6, 500ft but across these plains there run deep gorges called Quebradas. Through these gorges team the sporadic floods that tear down from the high Andes in the summer.

We tried in vain to access some of these precarious gorges, native Algarrobo trees often found a niche at the foot of the cliffs in which to grow and small groups of Grey-headed Sierra Finches were usually present.

Continuing in an easterly direction towards the Andes the altitude increases and so does the wildlife. One special habitat in the Atacama are the saline lakes, salars. These are fed with underground water from the Andean snowfields. These saline lakes are a magnet for waterbirds such as Andean Avocets and Flamingos.

When the altitude reached between 6,000ft – 11,000 ft we encountered an area of the Atacama known locally as the ‘andean desert’.

Parts of this area are extremely arid but luckily receive run-off from the high volcanic peaks and cacti predominate, particularly tall stately Cardons.

It was in the Andean desert that we found the greatest biodiversity.

The most obvious animals were lizards, sunning themselves on rocks or scuttling across the stony ground away from our tramping feet.

It’s quite easy to catch a lizard, one just has to be very patient, careful, slow to start with and very quick at the finish!

Once you have caught your lizard it’s possible to admire its beauty in detail, taking care not to hold it by its tail or it will shed and you will be left holding a wriggling bit of discarded flesh.

Often in the chase the lizard will try to escape, they will hide in a spiky bush, under a rock or disappear down a hole.

Finding them in these situations can be interesting and rewarding, if not scary, for in such places we found scorpions, spiders and numerous beetles.

Some of these animals are not everyone’s favourite but we like them! In the driest place in the world it was fascinating for us to discover at last so many animals.

As a complete contrast to these small creatures the next blog will concentrate on one of the largest, most beautiful and graceful birds of the desert; the Flamingo.

Out of this world in the Atacama

March 31, 2015 by Michael

The Atacama desert stretches for 600 miles from the north Chilean coast into southern Peru and eastwards from the Pacific up into the Andes mountains.

This is where Paula and I have recently been travelling in search of wildlife, though it’s hard to find!

A few main roads cross the desert as mining is a major industry in the region.

When we left the main roads we were stunned by the emptiness and the vast, parched, barren landscapes.

The Atacama desert is the driest place on earth. Most parts of the desert only receive between 1 and 3 mm of rain a year and scientists have concluded that some areas have experienced extreme aridity for 3 million years with some river beds being dry for 120,000 years !

For a landscape photographer, being in the Atacama is like a visit to a modern art gallery.

Colours are bold and saturated, lines are clear, everything looks clean, nothing is cluttered and yet unnatural in a peculiar way.

The senses are not bombarded by noise, the silence accentuating the sharpness and intensity of the desert and this is what makes the Atacama so beautiful and other worldly.

This is not only a land of stone, rock, sand, salt lakes and lava. It is an explosive and turbulent land as the underlying volcanic activity sends steaming water to the surface, bubbling through boiling mud.

Primitive bacterial organisms have been found in these cauldrons of steam and slime.

It is not surprising that NASA scientists use this desert as a testing ground for their explorations on Mars. Nowhere on earth looks more like Mars than the Atacama, nowhere on earth is there less life than in parts of the Atacama.

It might seem crazy that we would visit such a desolate and unforgiving environment in search of wildlife. But, as always, nature finds ways to overcome the seemingly impossible and has conquered even this hostile place.

Such were the secrets we uncovered and the animals we found that the next two blogs will be devoted to the extraordinary wildlife of the Atacama; the driest place on earth !
