Changdeokgung Palace - painted patterns

From once being a Primary School Teacher in the United Kingdom i am swiftly aware of the patterns that we see around us.  Here is a little different because they are painted so beautifully and (as indicated previously) so beautifully maintained.

Changgyeong Palace - no birds?

The palace is a beautiful piece of architecture and the gardens match - beautiful.

But there are no birds - is this their only protection?
