Happy feet

The blue-footed booby (pictured) is an extraordinary-looking bird. It has fairly dull plumage but strikingly coloured blue legs and feet. What could be the evolutionary benefit of such a conspicuous feature? Both sexes have blue feet so they don't seem to be for impressing potential mates.

What kind of bird made these marks? Is it usual for them to peck in symmetrical patterns?

I found the pattern shown in the attached photograph in the snow on my lawn on Christmas Eve.  I assume the two 'arcs' of straight lines were made by a beak, as the lines across the pattern appear to be bird tracks.  The arcs are about 20 cm apart.
