I visited Argentina for an hour or two in 2009, when I popped over the border from Brazil at the Iguazu Falls, and saw many Brazilian Cavies and Coatis plus some Brown Capuchins. I visited again, for a week of work and mammals, in June 2017 and spent a weekend in Entre Ríos province. And I was back in September 2018 to spend 3 days on the Valdes Peninsula.
I spent a night here in 2018, and saw a Large Hairy Armadillo, Coypu, European Hares, Patagonian Hog-nosed Skunks and a Grey Leaf-eared Mouse.
The Valdes Peninsula
I spent two nights on the beautiful peninsula in 2018 and saw Larger Hairy Armadillos, European Hares, Southern Mountain Cavys, Patagonian Maras, South American Sea-Lions, Southern Elephant Seals, Humboldt’s Hog-nosed Skunks, Southern Right Whales and many many Guanacos.
El Palmar National Park
I spent a couple of nights in the lovely El Palmar National Park and saw Lesser Grisons, Geoffroy’s Cats, a Six-Banded Armadillo, Plains Viscacha, Crab-eating and Pampas Foxes, Capybara and Grey Brocket Deer plus introduced Chital. All these species seem quite common in the park, even the grisons!
Some small mammal traps around the Aurora del Palmar hotel caught four species: Crafty Vesper Mouse, Red Hocicudo, Azara’s Grass Mouse and Black-footed Pygmy Rice Rat.
In the gorgeous wetlands near Ceibas I saw some Coypu, and caught a Red Hocicudo and Kemp’s Grass Mouse (Deltamys kempi).
