They are very high-energy indeed @ratel :) Most of the time they take a rest in the opening of the drainage pipes that flow underneath the sea wall; it's a very safe place for them to take a break. Of course when you want to catch them where they normally are, they're not there ;)

Otherwise they'll perch up in the trees that line the sea wall, but it's a bit too high for a good shot :)

Thanks for the comment and the support :)
