Hummingbird and Sunbird

A kind-hearted boy saw a small sunbird outside his house and brought the bird to school and asked Uncle Jason to hand to Mr. Koh. He thought that this was a Hummingbird. Unfortunately, there's no hummingbird in this region, exception Jurong Bird Park. Apparently, this is a Olive-backed Sunbird. Mr. Koh went to a bird shop to ask for the price of a birdcage and the cheapest cost $18. He decided to setup his own bird cage for the little sunbird. Poor Mr. Koh has to baby-sit the bird for the weekends. Here's a photo of the sunbird and the website that also provides some info about this specie of bird.
