Greek chimney cowls that look like birds

Last year when I was on Crete, Greece, I was surprised to see chimney cowls that looked like birds. At first I thought it was just my imagination until I started seeing lots of them. This year I was on the Greek island of Zakynthos and again I saw these chimney cowls.

I googled them and found there is a manufacturer in Greece. There was no explanation, I assume it is just for decoration. These are what he produces -

And these are some of the chimney I saw. The first 2 I saw on Crete -

and these were on Zakynthos -
