Birding Buenos Aires City

Here we refer to just the greater metropolitan area of the capital city – there is a separate page for the state of the same name. Having so many distinctive natural regions, Argentina offers very interesting birding opportunities. The wide latitudinal range includes tropical rainforests the north to the vast wind-swept Patagonian steppe in the south. The central pampas and hills, the Andes mountains along the western border with Chile and the eastern seacoast complete the basic picture of the country.

Argentina is still mostly wild and unspoilt, so visitors will be fascinated by the wide expanses, the great views and the chance to bird in solitary and remote places. In contrast, Buenos Aires is a large city. Even so, there are a number of nature reserves, which are good for birding. Of outstanding interest is the Costanera Sur Nature Reserve, due to its immediate proximity to the city centre, making it very convenient. Other nearby sites, described below, are also of interest.

Many farms close to Buenos Aires offer day visits to see the pampas. Some are geared as a show of traditional gaucho activities (dances, rodeos, etc. plus the incomparable asado barbecue,); but others do offer good birding outings, which will typically take you out on the grasslands, through native or implanted forests and past swampy lagoons. To get further afield, tour operators provide excellent day trips and longer excursions to spot Argentina`s more than 1,000 bird species. The main places are outlined below…

Trip Reports
  • 2016 [02 February] - Alan Tate - Buenos Aires to Los Angeles Cruise

    So at the end of February we arrived in Buenos Aires, the day before our huge cruise liner was due to sail. A quick look at Costanera reserve was in order, but sadly "progress" has reared it's ugly head in the ten years since our previous visit. Most of the same species are still there, but the trails have been widened, the marsh area is much more vegetated and difficult to view. Whilst this is obviously better for birds the trails are now in use to a large extent by joggers and cyclists, so many birds are now staying hidden that used to be easily viewed.
  • 2022 [11 November] - Colin Reid

    PDF Report
    ...Creamy-bellied Thrush (4) in the main square and a Harris’s Hawk near the main cemetery which one of the other ‘tourists’ pointed out. The view was a bit shit, but happy with it. Also had great views of Monk Parakeet (20 in the La Boca area) but had seen them, as an established introduced species, in Athens, Greece...
