Guinevere and Evelyn were both acquired by the zoo in 2016 from a rehabilitator. Both owls were determined to be not releasable back into the wild due to the inability to successfully hunt. Guinevere can often be found on the lower perch of the enclosure. Due to neurological damage, it is easier for her to perch at this lower level.
