There are three main spots for observing birds in Buenos Aires: Costanera Sur, Ribera Norte, and Vicente López Ecologic Reserves. You can see birds all year round because in different seasons there are various species of birds around.
The Reserva Ecologica Costanera Sur is a magnificent park with beautiful architecture and sculptures, casual eateries, and picnic areas that invite everyone to relax in nature. Also, it's a great destination where you can observe many species of birds. The reserve area is of approximately 350 hectares. There have been more than 300 species of birds sighted, including many species of waterfowl—ducks, mallard, swans, coots, and gallinules. In addition, from spring to autumn migratory birds fly here including plovers, sandpipers, and yellowlegs. Bar-winged cinclodes, dark-faced ground-tyrants, and rufous-backed negritos come from Patagonia to winter in these lagoons.
The next spot is the Ribera Norte Ecologic Reserve situated in the north of Buenos Aires. It is smaller than the previous one, but with a rich diversity of birds. Here you can find Brazilian ducks, plumbeous rails, rufous-sided crakes, yellow-billed cardinals, and red-rumped warbling-finches. During the summer migration season, bran-coloured flycatcher and the red-eye vireo come as well. In winter one can see white-throated hummingbirds.
The Vicente López Ecologic Reserve is the smallest of these reserves and is a good spot for aquatic birdwatching.
