Birding Site Guide

Las Grutas is easily accesible from San Antonia Oeste where there are several places to stay and eat. We stayed at the Hotel Iberia on Sarmiento (40 pesos for a double). Buses leave for Las Grutas from the Las Grutas bus terminal (as locally). It takes less than 30 minutes and costs 2 pesos. Get off the bus at the end of the promenade where the bus turns and goes back the other way. After here is a small dry canyon. Along there is good birding especially where a thin, black, leaky pipe crosses. Lesser Canastero was seen in this area. Walking further along the road towards el Salto, Golden-billed Saltator and Chalk-browed Mockingbird were seen in roadside scrub. A couple of km further along, the 3rd canyon along (almost wide enough to drive a car down) seemed to have good habitat and some interesting birds had been seen there before. All I saw of interest though was Patagonian Canastero. I saw 32 species including 4 lifers.
