I notice that on one of the Children's channels on BBC there is often a
loop playing of birds and sounds like in a quiet street, I cannot see the
picture, but I'm assuming there is not one. Obviously these channels tend to
not be active when another channel is to even up the bandwidth use, but why,
then do they waste it with audio, and if its insignificant, why not use it
for something useful instead?

Perhaps this is a "test card" type function for checking "tuning", etc?

I remember that Classic FM used to play out a recording of the sounds of
a summer garden (complete with bees buzzing past the microphones) for a
few weeks before they started official broadcasts.

There is (or at least used to be) a picture, showing an animation loop,
saying something like "CBeebies is having a little nap"

It's there because BBC Three used to share that slot.
