These islands have been a source of guano fertilizer since pre-Columbian times. Most of the birds in the first two pictures are Peruvian Boobies. The third picture does not do justice to the wintering Chilean Flamingoes in a bay on the Paracas Peninsula. Driving from Paracas to Lima we saw the above-pictured rocky beach and drove right down to it. This is a llama.
Alpacas look similar.
We did not see a vicuna. The most conspicuous birds in the flocks we had along those RR tracks below Machu Picchu were the beautiful Saffron-Crowned Tanagers. Stauffer pointed out a Dusky-green Oropendola coming out of its pendulous nest. Nevertheless I may have loved this trip most of all. I took the snapshot of the women from the Machu Picchu train window.
