More Pink Ring-billed Gulls at Oshawa

Three Ring-billed Gulls with pink flush were among normal ones at Oshawa Harbour on 18 February 2016. At Ajax Rotary Park on the same date there were none among 180 Ring-billeds. At Frenchman's Bay on 21 February, one was among about 150 Ring-billeds.

All three pink ones also had vivid yellow legs and bill.

Pinkness in Ring-billed Gulls is supposedly linked to diet. What are these birds eating to trigger this pinkness?
