This enclosure is found within the zoo's nocturnal house, named Twilight. It seemed empty and I forgot to note what species of armadillo it was but six-banded armadillos were kept elsewhere in the zoo, so I'm guessing this was their old enclosure.
A Prevost's squirrel, otherwise known as an Asian tricoloured squirrel, at Northumberland Country Zoo. The photo was taken with my phone camera so not the best quality.
