The Black and the Whitish Part !!!

You will be surprised when you read about this new and interesting information about swiftlet spools (poof or shit).

A new BH owner will be very happy if he sees lots of bird shits on his new BH floors.

This indicate there were birds that entered and stayed in his new house.

The new discovery that I wanted to share to my blog reader is why the spool are black and white in colour.

Usually the bottom part will be black and about 1/2 inch while the white looks more like being splattered on the floor.

The black part drop first and soon after the white part drop in liquid form.

I met this old friend of mine who happened to be an animal doctor.  He operate his own vet clinic in Sibu Sarawak.

"Harry the black part is the spool while the which coloured material is actually bird's urine."

Those birds when they do their business they will do both shit and urinate, according to this experienced Vet.

This information is interesting and new to me.

My nest question to him was like this:

"Doc when our BH is new or if we play a new sound the floor seems to have more white (urine) as compared to black (spool) coloured portion?"

His answer was simple:

Those are the kind of spool from young birds.  Their spool are with more white as compared to black coloured.

Reason being they are still not strong enough to catch those insects.  Less insect consumed means more water out of their body.

It make sense but I do not have any thing to proof otherwise.

So as at today you can easily guess what type of swiftlet are staying inside your BH.

Those will lots of white coloured materials in their spool are young birds while the standard matured birds will have less of the white coloured.

I hope this small information is useful to those who happened to see many kind of colours in a group of bird shits on the floor.
