My Bla Bla Bla on Swiftlets,

BHs with no nests, please don't worry if your BHs are in prime location. If you really have no confidence in yourself or in what you are doing, sell off your BHs and sit by the side line and let others do the kicking.

Before anything can happen, the area must be suitable for the birds, then you will have what I called a core for the birds' sanctuary. First, a few birds will stay in a few surround Birdhouses and that circumference will gradually but surely increase in area and will cover bigger diameter as time go by taking consideration of whether the core operators are really bird's breeders or not. If your area is in the core of the sanctuary, you shouldn't have a problem to attract birds and if you fail, you are to be blame and you may sell your BH to me anytime and sell 50% to me anything.

If your area is out of the core of the sanctuary, you must wait with patience like father waiting for the baby to be delivered. No rush because  it is not in your hand but the hand of the core's BHs owners and also God's hand. Which direction does the expansion is also a matter to discuss NSEW and that's will normally depend on the flow path  of the birds.

If your area is far away like in the case of Desa or EcoPark, you need to be more patient if your area is in the feeding or flow path of the birds from the town where your BHs will lure the young ones to visit your new hotels for evaluation for new home.

Provided if the birds still with the town and your area is in the path, you may be fortunate to start a new colony of birds. Pulling in new birds from the town where the places are all full. Once the town's core area is destroyed, all Desa and EcoPArk will fail cos they are not the core of the santuary. Core are where the birds choose to be there and what make the birds stayed in the town more than 50 years ago.

My friend's house already has nest more than 50 years ago then, they don't even know that that are EBN sticking on to their wooden beam until the Indo buyers came to buy from them. They feed the nests  to the dogs and dogs don't even like the nests.   

So, the story is that the birds choose to stay in town first  and later, we only provide them with more areas to stay. Why don't they stay in desa 50 years ago and I can only think that the swiftlets feel safe in town.

Only so much that my little own experience to share and all thru my eyes.....if the authorities really interested and honestly in wanting to make the country a top producer, talk to us.. and please listen.
