The area has a long history of visits by explorers and english pirates. Chrales Darwin arrived in December 23, 1833 and navigated up the river where he set up camp. He described the topography, geology, flora and fauna; in particular. He extensively elaborated about the behavior of the guanaco which was very abundant in those days. About 20 miles up the river, there is a promontory known as "Miradores de Darwin" that offers stunning views as seen above. Neaby by there are caves with ancient indian paintings of hands all over the walls.
The island of the Pinguinos, currently a protected national park with an abandoned lighthouse, is the home of Magellan penguins (above), rockhopper penguins, skuas, cormorants, sea lions, and elephant seals and many more.
The island is home to the only colony of rockhopper penguins in coastal Patagonia. They are smaller than the other species of penguins I have seen. The adults have yellow feathers resembly eyebrows that make them very attractive.
When I visited in early February, most of the chicks were fully grown and showing almost full adult plumage. They were still been fed by the adults and are not afraid of humans and easily approached.
For the first time I had a close encounter with skuas. They are very aggresive and will dive bomb those approaching their nest of chicks. I was subjected to their repeated attacks and my hat what hit on occasions. Nevertheless, I managed to get a photo of one of the chicks; imagine such a bellicose attitute to keep me away from such an ugly thing.
In the way back to Puerto Deseado, I was rewarded by a visit from a family of dolphins that for some unknown reason, are attracted to boats and performs aerobatict shows...and it is free!!!
I also visited the national park that follows the Deseado River upstream. Soon after driving into the park late in the afternoon, I encountered a small farm house selling "range eggs." Following the road to the right I ended in a canyon; it is very narrow with high rocky walls full of small cavities and caves. It was obvious that this formation was under water eons ago. I soon was rewarded by an owl family who granted me the opportunity to observe their hunting behavior.
Farther up the park, there is a gray cormorants colony nesting in the cliffs that offered me an opportunity to photograph their nesting behavior under challenging photo conditions due to their flying speed and poor lighting. They are the most beautiful cormorants I have seen so far.
