Came across this pair of Kingfishers busy digging their burrow on a lakeside near Thetford. Great to observe them going in and out taking in turns to dig, and chase away unwanted attention from another male in the area. Difficult photography conditions as the site is about 50M from the nearest observation point, so need long lens plus extender. Also, the site is a bit in the shade, but great to see them flying around each other with the odd fight along the way. Only way to tell the sexes apart is the female has a reddish bottom to her beak.
