Gulls or Gannets?

Headed to Kaikoura this morning for the night, with TeeJay, mum and sis in tow. We dropped mum off at the motel and then headed back out to Ohau point where I took lots of fairly cool shots of seals and waterfalls. Before getting there though we stopped at a cafe on the Kaikoura coast and these gulls made very short work of the leftovers. Was Tippi Hedren's worst nightmare!
