I made my first return visit to the Louisville Zoo in over 10 years this past Saturday while spending the weekend visiting a friend, and have added a handful of photos to the gallery. I'm afraid that I cannot provide a comprehensive update on the zoo, as I was not on my time, but rather my friend and her boyfriend's, so I spared them and refrained from fully indulging in the experience

That said, I do have some updates!
1) The zoo recently received a pair of one-year-old common warthog brothers, named "Digger" and "Riggs", from the Erie Zoo.
2) The zoo's 23-year-old male Komodo dragon, "Big Man", was recently euthanized after suffering from severe tetraparesis.
3) The last two brown woolly monkeys in North America have been taken off display to make way for the renovation of their exhibit into a new exhibit for colobus, which was supposed to open this year although there appears to have been no construction work do so far at all. That said, you can still catch a glimpse of them in a cage behind the giraffe barn and the wattled stork exhibit.
4) This was my first visit to the zoo since the opening of Glacier Run, and I have to say, I was quite impressed! The rotational bear exhibit is very nice, and the pool is spectacular! The Steller's sea eagle aviary is also very impressive and a huge improvement over their previous home in the giraffe barn; although it does not quite offer nearly as many true flight opportunities as the aviary in Cincinnati. The pinniped exhibit and underwater view was rather average, but the views into the bear exhibit were very nice, indeed. I thoroughly enjoy Louisville's commitment to the rotational exhibits; however, I wish that there would have been another bear yard instead of just the indoor bear exhibit - especially with how many bears they have.
5) I also got to see their brand new little blue penguin exhibit, which just opened this past summer. While none of the penguins were out during my visit, I can say that the exhibit is still very nice - undoubtedly the best little blue penguin exhibit I have ever seen. It is a very large, netted exhibit with sandy beaches, rocky patches, and clusters of beach grasses. The pool seems a little on the shallow side (I've honestly never seen a very deep pool for this species), but it is surely large enough in size. Unfortunately, I was unable to get any photos of the exhibit because this was the last exhibit we toured before leaving for the day, and we had reservations to make.
These are the biggest things that I noted on my quick visit, but if anyone has any more specific question I might be able to answer them as well.
