"Seriema Nature Tours organized a perfect 8-day bird-focused trip for the two of us in Buenos Aires, Ibera Marshes, and Iguazu. We never had to worry about logistics, which were carried out flawlessly. Lodgings were all good quality, and food well-prepared, varied, and plentiful. Our guide, Diego, was highly personable, and we very much appreciated his bilingual ability as we are quite limited in Spanish. He knows all the English names of the birds, but more importantly, his skills in identifying birds by sound and quickly spotting them, affording us satisfying views, are outstanding. This was our first trip to Argentina (our 7th Latin American country), and even though we birded in a limited region, we picked up 222 species of which 115were lifers. Highlights include the Yellow Cardinal (endangered and near-endemic), Blond-crested woodpecker, Yellow-fronted Woodpecker, Ochre-collared Piculet, Streamer-tailed Tyrant in display, Jabiru, Swallow-tailed Manakin, Magpie Tanager, Green-headed Tanager, and in the Iguazu hummingbird garden the rare Swallow-tailed Hummingbird, to name just a few. Highlights on our itinerary include the boat rides in Ibera Lake (especially the sunset ride), where we got very close to a pair of Southern Screamers, and early morning birding on Road 101 in Iguazu. And one must not fail to mention the spectacular Iguazu Falls. Besides appreciating this natural wonder, we enjoyed the myriad butterflies which floated around us and often alighted on us. A bonus on our itinerary, because it was a cultural site, was a visit to the Jesuit Guarani Mission Ruins at San Ignacio, which gave us a glimpse into Argentina`s ancient and colonial history, led by an excellent bilingual Jesuit guide. All around, we had an unforgettable tour, and we highly recommend Seriema Nature tours."
