There are four species of squirrels in Costa Rica but the largest population nation-wide is this Variegated Squirrel, Sciurus variegatoides (Ardilla Centroamericana en español) with the names linked to my photo gallery with shots from nation-wide. I think they are like squirrels everywhere, very hyperactive! 🙂 And though I have seen a solid black one and a mostly red one, most are variegated like this one in my garden.
¡Pura Vida!
