A Very Strange Thing That Happen In A 350K BH !!!
This weired story have to do with territorial behaviour of Swiftlet King or a Leader.
Remember my article about swiftlet colony members who tend to be aggressive when their colony numbers grow big enough.
They tend to chase the other smaller colony size members away and overtake their territories (if you do not build a colony divider).
Those smaller colonies will eventually move away to another suitable location or maybe find another safer BH nearby.
The lesson here is that there is a kind of territorial protection behaviour pattern that are being practise by these wild birds.
Beside becoming aggressive, these birds also mark their territories by using their shit. Good example are those markings on the walls of the roving areas. If you look at the pattern of those shits on the wall, they were all intentionally made and not by chance.
The birds need to bomb the wall while flying. They need to fly as such they shit must hit the walls. Can you visualise how difficult it was but they do that for a purpose. Territorial marking !!!
Another interesting method is by the use of sound. The dominant leader of the colonies will give a loud shriek or call to announce his dominance.
This special sound made do make the rest very scared, run away, keep quite or not willing to be close by or even stay in the same BH.
This was what possibly happened in a 350K BH with only one nest.
This BH owner has his BH put into operation for almost 1 year plus. After so much money invested he was hoping to get his BH filled with swiftlet nests.
Months after months the birds was staying away from his BH except one couple.
It seem that this couple has a very dominant character so much so no other birds dares to build their nest inside the 350K BH. Even their own babies will stay away once they have taken their flight. (I assumed so since after more then a year there were no sign of any nest in the BH)
The owner was very disappointed with the only one nest so he decided to do the extreme.
He closed the entrance hole and one night he use those net to catch the couple.
He literally kill both of them.( I am not too sure how they did them).
Once that was done, after a few short weeks, the house begin to be populated by those new young birds.
It was very strange but it can be due to the dominance of the previous tenant.
Too bad they were no longer alive to explain to us what they actually did to scare the rest from entering the 350K BH.
This real event was told by one of my blog reader during my occasional meeting with some.
