My favourite method to check if a BH is having visitors or not is by inspecting the monkey house walls.
Those that do not have monkey house I will look at the roving room.
The number of bird shit spots splashed on these walls will actually give you a very clear signs on the number of birds that visited the BH before you entered.
All this while I thought those shit markings were territorial markings however during my last meeting with a famous Sibu Vets he says it was something else.
"Dr K, what is your opinion about those bird shit spots on the monkey house or roving rooms walls?" I asked.
Actually it has something to do with the effect when those bird apply their speed breake. Most of them will fly at a high speed and once they entered your Monkey house they need to slow down. This will cause some of the body muscle to squeeze to control the speed. When this happened they will squeeze their bowel thus forces either their urine or shit out.
You see those white colored shit or liquid are actually their urine while black color solid are shit.
Hmm... a very interesting new theory from a Vet.
I learned something new and I think there are some common sense in his explanation.
You might have other explanations but try me.
At Dengkil BH I took a number of photos to keep inside my record folder. Let us see how will it grow and with the growth we can safely says that the BH is doing well receiving lots of visitors.
If the number is great but the nests numbers are low we know that there must be something not right with our BH internal design.
It might be the darkness not right or the high temperature or too dry inside.
If you cannot determine the reason get some one who knows the answer.
Get him over and ask his for a full report what he thinks are wrong with your BH.
Insist for some recommendations on how to correct these errors.
Follow his recommendations and I am sure you will change the fate of your BH.
