On the way to Papua New Guinea and on the way back I had layovers in Singapore. I purposely took an extra day on the way there so I could visit my favorite bird park: Jarong Bird Park. I've been there before and this day spent my entire day there.
I stayed at a hotel actually in the shopping mall adjacent to the airport that is a convenient walk. It is called Yotelair, and provides very small rooms where you hardly need to get out of bed to go to the bathroom. But it is clean, the bed is motorized so you can sit up, and the shower is deluxe. The mall is called Jewel and is five floors built around a giant fountain that spews water from the top, and is lit in different colors in the evening.

The bird park itself is going to be combined with the Singapore Zoo in the next few months. It has two great shows with birds that fly around the audience. One is primarily parrots and macaws, and the other is raptors.
