I also was looking for free things to do in Vegas and I guess I expected way too much from Flamingo's wild life habitat. On the brochure it said it would have penguins but I didn't see any. If you are staying at the hotel or are at the hotel anyway I would recommend going there and checking it out but it was definitely not worth walking all the way down the Las Vegas Blvd to see it. They have flamingos, swans, fishes, ducks.. and I think thats it.
