I am very curious about this particular question: What Time Do Swiftlets Go to Sleep?
Many would say that then will sleep at 10pm or worst case 11pm. This is because they are tired since they never stop flying the moment they leave the house as early as 6:30am.
Hmm I am not sure that they do sleep on time. I know for sure my wife goes to sleep sharp at 10pm but the swiftlets I am a bit confused.
You know why?
This everning at 9:30 pm I got this SMS from Mr.A of Kota Baru.
"Harry right now I am the Kota Baru Sultan Mujammad Stadium. You know what? The flood lights are on and there are lots of insects and there are also many swiftlets flying around having their feast."
In Kuala Trengganu, Jeff told me about this perculiar observation where swiftlets do come out of the BH and play around those streets lights. Most of the time they will be catching those insects hovering the light but some seem to be chasing one enother.
If you watch very very carefully, there are birds which actually fly out of one BH and enter the other BH. They must have two wives like those muslim brothers????
Well you never know what actually makes them not going to sleep to get ready for the next day.
We can just observe and do some prediction.
I think not all these birds go to sleep. Some might be a bit hungry so they sneak out and catch some insect from those street lights. Some might be just started their copulation excercise. Since they have eight days to keep making love, making love in the air might be a preferred position. So once the female flew out of the BH the male will follow.
As for the criss crossing from one BH to another it could be that a young birds that must have fallen in love with another birds from a separate BH. Once he feel rejected he might have decided to fly back home to where mummy is. Well you never know exactly but they could be anything......
Maybe Pak Hen can tells us more on what his version of this late nights behaviours.
If you have something that you think you wish to share, just write your comments.....

From my understanding from books, swiftlets do mate and sleep while flying high up in the clouds.
Harry,
My 1 st. new bird house just openned for the past 5 days. I viewed through the recorded CCTV & noticed the birds (ard 20 of them) will never moved after that: 10pm, 12mn, 2am etc.). What a lazy guys, at least do something la.. ( I splashed a lot of hormone in the house). Is there any other ways?
Kenny,
Congratulation for the new BH. I hope those birds will find your BH attractive.
Since U said that U have splash those aromas already, why don't to fix a tweeter at the far corner of the room, away from the entrance hole, running the same external sound.
Do that and I guarantee U they will come in. Make sure the sound level of the said tweeter is not too loud.
