GULLS SPENDING SUMMER HOLIDAYS IN BRIGG

A flock of about a dozen black-headed gulls seem to have made the Cary Lane area of Brigg their summer holiday base. Presumably they've come in from the coast. The gulls are finding plenty to eat in this part of town, notably discarded take-away meals around the bus shelters.
We seem to recall that black-headed gulls once had a strong base in Scawby Park decades ago, a stretch of water there being dubbed the Gull Ponds. Anyone able to throw any light on that for us?
