Yes, we also have squirrels in the rainforest.
At first I even didn't know that there were also squirrels in the rainforest of Suriname. The first time that I have seen a squirrel in my life was around 8 years ago. It was during one of my first birding tours and when we stopped to look for a bird, we saw a squirrel right under one of the branches. It was getting dark so I didn't manage to take a photo of it.
But years later, I started to see them moving in more sunny places and they were also so nice to stand still for a couple of seconds. Enough for me to take some photos. So this is the Guianan Squirrel (Sciurus aestuans), locally known as Surinaamse eekhoorn or Redi bonboni (sounds so cute). The first thing you will notice is their long fluffy tail, when agile they move their tail quite funny. Seems like their little antenna moving to all different directions.
Their day animals or diurnal and I have seen them always 'hugging' trees like a woodpecker or woodcreeper. Usually working their way up. Seeds and fruits are part of their daily diet.
A couple of times I have seen them with birds in a tree. Here for instance, one Guianan Squirrel was seen with a couple of Yellow-tufted Woodpeckers. Both minding their own business.
They are one of the cutiest tree huggers I have seen so far in the rainforest.
