It’s lively out there on the shoreline as the Southern Black-backed gulls breed from September through to March but mainly now, in November.  They’re a robust species, dominating the shoreline and top of the pecking order when it comes to muscling in on opportunistic feeding.  I was intrigued to see two adults tussling in a ‘beak pulling’ contest.  I wondered if it was a play for dominance or perhaps a mating ritual.  Anyone have any knowledge on gull behaviour?
