Sunbird removing faecal sacs

posted in: bird | 0

Sunbirds have been building their nests on my bedroom balcony ceiling for 12 years . I think it’s because we have ginger flowers in the planter around the balcony. The first nest appeared soon after we planted the ginger flowers ( Heliconia sp.) .

We realized they build their nests from hanging plants and there is a corner of the balcony they favor so we put a money plant (Epipremnum sp.)there to entice them.

On 10 April 2022, the female started her building and the nest was completed around 20 April when I spotted her sitting inside the nest.

Not sure when the egg/s hatched as I can’t see inside the nest and don’t want to cause any disturbance.  All the photographs and videos were taken behind glass with an iphone in Tanglin.

Olive-backed sunbirds are known to complete the nest building one week before they lay their eggs. The 2 week incubation period is followed by nestling care for 2-3 weeks before they fledge. Egg incubation in this bird couple could have begun on 28 April 2022.
