I suspect it was hunting grasshoppers or maybe even mice.
The Ria Formosa is a lovely place to pause for a minute
Exploring how the changing light (and tide) affects the same view
It is a tip I strongly recommend!
It’s a rather wonderful place to rest a while
Amazing what you can find if you stray off the beaten track
A reminder for me and for you of why we keep returning to the Algarve.
