If you are passionate about birdwatching, nature and photography, this private experience is an excellent opportunity to discover the Costanera Sur Ecological Reserve, Buenos Aires’ main urban birdwatching hotspot, located next to the Rio de la Plata and a few minutes from the city center.
Together with a specialized local guide, you will walk along trails, lagoons and wetlands where you can observe more than 300 species of birds, as well as other wild animals in their natural habitat.
The reserve offers excellent opportunities for bird photography, wildlife observation and contact with nature without leaving Buenos Aires.
It is ideal for birdwatchers, photographers, nature lovers and travelers who enjoy these activities during their stay, stopover or cruise in Buenos Aires.

Depending on the time of year and the conditions of the day, it is possible to observe waterfowl, raptors, migratory birds and many species typical of the Pampian wetlands, in one of the most important areas of urban biodiversity in South America. We have a long-range telescope to appreciate birds up close and, if you don’t have your own, also shared binoculars.

Honestly this birding trip could not have been better. Javier is a wealth of knowledge and he makes every effort to make your birding dreams come true. He is incredibly talented and we feel lucky to have birded with him while in Buenos Aires.

On my journey home to the UK from a trip to Antarctica I had a free morning in Buenos Aires; 3 hours birding in the Costanero Sud Eco Park in the centre of the city was an excellent way to spend it. Urban birding at its best. My guide was Javier from Pampas Birding, a charming man and an expert birder. 60 species on the list by the end of the excursion. Price included pick-up from and return to my hotel so all very easy. All birders and non-birders (Javier has a scope so no problem if you don’t have binoculars) would enjoy this outing.

I'd been to Costanera Sur on my own twice during my stay in Buenos Aires but I'm not the best at identifying birds. Fortunately, I found Javier on TripAdvisor for a private tour. He picked me up at my apartment and took me to the preserve and in just 3 hours we were able to see 71 species and over 30 new lifers. It was a lovely, warm (but not hot) morning and Javier was wonderful to be with and talk to. His birding knowledge is immense and he's fluent in English. As a woman traveling alone, I felt safe and highly recommend Javier. It was a highlight of my two months in Buenos Aires.

Javier picked me up at my hotel early on December 24th. I was impressed he had been in contact with the guide I had just spent 5 days with to get a list of birds I still needed. When we found the reserve closed due to combination of slippery muddy trails and it being Christmas Eve day, Javier immediately had another plan. The Tripadvisor tour is 3 hours, but even on a holiday, Javier was happy to add 3 more hours . I always felt safe and cared for, learned a lot, and saw some amazing birds. I highly recommend Javier as a bird guide.

I had an absolutely lovely morning walking through the nature park with Javier! We saw 61 species of birds and I felt completely comfortable being a solo traveler. Highly recommend this tour!
