One pair of bird occupied a long fake nest, about a foot long.
The fake nest was installed and sprayed with Super Pheromone aroma.
The moment this couple located the fake nest they became territorial.
What happened was that they wanted to keep the fake nest to only them self.
The two quickly erected applied their saliva and the whole one foot fake nest soon were with their saliva.
Due to that other swiftlet don't dare to come near.
After some time they occupied only one part of the long nest.
In this case at the end of it.
This proof that these birds are very territorial and don't like to share things.
Similar to human being especially those who have successful BH.
They become so greedy and refuse to share their secrets.
Enjoy these pictures and I hope you will experience the same inside your BH soon.
Remember this also proof that the Pheromone is very effective.
