You’ve a good chance of Oriental Pied Hornbill plus loads of other stuff like White bellied Sea Eagle, Brahminy Kite, Dollarbird and lots of other goodies. Also a stroll along the sea walk will get you Kingfishers. All very close to the airport. Just get a cab to the Changi Village Hotel.
That could be a really good game plan if you have only a few hours. Besides the species mentioned above, red-breasted parakeets are all over the place in that area and you should have a great chance of spotting Tanimbar corellas and possibly other introduced cockatoos. From the Changi boardwalk you may see passing terns and the Ubin telecoms tower, from which migratory peregrine falcons have often been reported, can be seen. I spent a late December morning there hoping that one would appear and hunt, but alas, the only raptors I saw (great views though) were the two mentioned by Digbert above. Changi village seafood centre also offers grub and cold drinks (not to be underestimated when tramping around Singapore!).
