I've filmed over a month and a half this very cute sunbird family nesting on our balcony.
You will see in this video how the nest is built, how it's kept clean, how they feed the chicks, and how fast they growing.
The lighting wasn't the best for filming because we covered the balcony with blinds and nets, leaving just a small gap to protect them from predators

the 2nd chick left the nest this morning: 15 Jan 2013
