Rare ducks which are native to North America have been spotted attempting to breed in East Yorkshire.

The male and female blue-winged teal were spotted at Yorkshire Water’s Tophill Low nature reserve, near Driffield, on a number of occasions over the past 12 months.

Despite being observed in nesting behaviours, it appears the birds were not successful in breeding at the site, where nature reserve wardens and volunteers kept their presence a secret.

However, it is “likely” they have attempted to breed in the area, which is thought to be a first for the UK, Tophill Low warden Richard Hampshire said.
