Avocets and mud
It’s odd that most wading birds are brown and heavily camouflaged and yet Avocets are, well, noticeable.
I wonder why? I’m sure someone will crack the enigma in the future, a little like there’s now an explanation of the Zebra’s stripes, in that they confuse insects and stop them landing. Whatever the reason, it’s fascinating and Avocets are always a pleasure to see.
