Kingfisher nests 2016

I've got lucky again this year in finding two Kingfisher nests.
At the two sites I've seen the Kingfisher going in and out of the nest.
Both nests are on the River Cole, Birmingham though they are quite some distance between each other, on opposite sides of Birmingham.
One nest site bank is as you'd expect it. A very high bank, a few metres up from the water.
The other nest site can only be a metre high and hid by growth at the river bank.
The calls the Kingfisher make to each other is great. The male letting the female know he is close by. It's the female I presume sitting on the eggs in the nest.
The male stops by to sit on a perch by the nest. Then the female comes out for a break.
At one site the male Kingfisher cuts through the trees nearby to do a U turn and go back down the river. Twice it flew past me only a few feet away. Great stuff!!
