“I am in Johor Bahru, Malaysia. A couple of sunbirds built a nest on my hanging artificial orchid. That was about mid-December 2016 (above).

“I only saw one egg (above) and eventually one chick a week ago. Wife said there were two chicks.

“This morning at 6am, the mother still flew in and out of the nest (above). At about 11am, wife said the chicks were missing (below). I confirmed it at 5pm.

“Very surprised. The chicks definitely weren’t ready to fly. Last week their eyes weren’t even open. No other animal threat was evident. Very surprised and sad. Really not sure what has happened.

“Most likely chick taken by a predator… see HERE.

“I believe that must be the most probable reason. I can’t imagine the adult birds carrying the chicks. However I am not sure which predator to put my finger on. The Yellow-naped Orioles (Oriolus chinensis) are nearby on a large tree. But they never come to my house. No cats either. Crows may be another culprit.”

    We had a second family of Olive Backed Sunbirds’ reuse the nest from the 1st family. We could tell they were different birds from the color of the male and female birds. Once again, 2 days after the egg had hatched, the nest was empty. At about 11am the previous day, we checked on the nest and the mother was snuggled in her nest. The next morning about 6am, She wasn’t there. We let it be until about 11am before we climbed to check and to our dismay, the chick wasn’t there.

    We can’t understand if this is a pattern among these birds. I doubt they can see in the dark. If ever there was a predator, it would have had to climb and then perch or slither into the nest which was hanging about 9 feet in the middle of my car porch.

    Hope to hear from anyone who has had similar experiences. It’s heart wrenching to not see the chicks grow up and leave it’s nest naturally.

    Regards,

    sorry, it should have read, 11pm the previous night. So I didn’t think it was possible for the birds to do any work at night because the next morning at 6am, it was missing.

  3. I suspect it was a snake or a predatory bird. Or, not probable, the parents kicked them both out of the nest. In ecology it is the “Food Chain” process at work. It is Nature’s way of regulating itself: I eat you, you eat me.
