We really enjoyed birdwatching with Agustin in the Puerto Madryn / Chubut / Peninsula Valdes area of Argentina. We were visiting Patagonia from North America and he was able to show us a number of new birds. Some of our favorites were Burrowing Parrots, the Magellanic Horned Owl, and King, Imperial and Magellanic Cormorants (nesting). Augustin is a wonderful guide. He is a nature enthusiast, knowledgeable, and an excellent teacher. We appreciated the time he spent with us. We were even able to spend a time checking out a hairy armadillo during our travels that day. We would love to go out with Augustin again someday and would definitely recommend this birdwatching tour to people of all abilities. He is willing to go the extra mile to give you the best experience possible. Thank you Augustin for an amazing day 🦉!

I did "long one day" birding with Agustin Esmoris on November 2nd 2018. We started the day with Golfo Nuevo area - the coast near Puerto Madryn and subsequently visited the valley area. We birded at diverse habitats - canyons, cliffs, lakes, and so on. Even though the day was less than perfect, it rained most of the time, at times bit heavy, we continued birding and managed to spot the expected species at each location. Agustin has intimate and up-to-date knowledge of the area which is very crucial for visiting birders like me who have limited time (in my case I only had a day at Puerto Madryn). This was my first time birding not just in Argentina but in neotropical region. It was fun and interesting to compare and contrast habits and behavior of "old world" species and that of neotropics. Thank you Agustin for a very rewarding birding day!

Thank you for a wonderful day birding in the Puerto Madryn and Trelew area. Your knowledge of the local habitats and birds to be found in each area was extensive and enabled us to see some really great birds, with very good views of many. I enjoyed seeing some nesting birds and the Burrowing Parrot wall. You worked very hard to find the endemic birds in the area and other specialities. I really appreciate your efforts. I got 23 new birds for my trip list. Best wishes

I visited Puerto Madryn as my final destination in my travel to Antarctica, Chile and Argentina. Before heading back home and booked a full day with Agustin. In 6 weeks I saw a total of 124 species, while on a single day with Agustin I saw 73 species. Agustin is very knowledgable about the area and its birds, and knows with almost pinpoint precision where to find them. It was very interesting to see the nesting sites of the Rufous Hornero, Burrowing Parrot, Turkey Vulture, Chimango caracara and Southern Crested Caracara. I would have never found these on my own and there lies Agustin's added value. He did his best to accomodate my wishes and the day was a very pleasant experience. I would recommend his services to anyone that wants to go birding in the rich and diverse area around Puerto Madryn.

Agus - thank you once again for such a fantastic day out birding in Puerto Madryn! Your skill as a birding guide is absolutely spectacular. Ted and I appreciated your excellent communication and detailed itinerary prior to our trip, your ability to identify every bird we saw, and your flexibility throughout our day together to take more time at some locations and less at others. We highly recommend your services!
