Wildlife cameraman Ian Llewellyn captures the rare sight of kingfishers mating in daylight on the River Wensum.
The birds breed in their first year and usually choose their partners in February, with two to three broods being raised in quick succession.
Kingfishers have been in the news in recent years for thriving along urban waterways, and they are also well established in rural Norfolk.
"There's rats in urban rivers and they often predate kingfishers," said Ian.
The 33-year-old is based in Bristol and has been filming for TV shows including Springwatch since 2006.
He has studied kingfishers since 2004 along Bristol's rivers.
