Most of the birding in Buenos Aires is in a nature reserve set up along the banks of the Rio Plata. There is an interesting mix of species in the reserve. Outside the reserve, the city is quite flush with Monk Parakeets.
Visits
- 2005-02-18: A walk around in the park for a couple of hours before we got back on the plane. The weather was hot and humid. The mosquito situation was fairly annoying.
- 2021-11-19: Walked from the hotel to the reserve, which it turns out, closes early. Anyway, you can still look for ducks from the outside.
- 2021-12-12: We returned to the marsh in the morning, and then we ended up there in the afternoon as well.
