Guillermo Vilas

Along the edge of the Costanera Sur nature reserve are sculptures of Argentinian sportspeople, including Gabriella Sabatini, but I liked the way the men repairing the footpath had appropriated Guillermo for their backpacks.
The reserve was great, but I actually saw more birds from this wall overlooking the open water than inside the actual reserve. The highlight for me was a glittering-bellied emerald (a gorgeous blue and green hummingbird) near the visitor centre inside.
