The early bird....

I was out in the forest near Hockham at 0300 this morning, and it was so beautiful, no wind, clear skies, about 13 degrees Celsius, comfortable between the heat of yesterday and today.
A hint of the forthcoming sunrise to the east but with the dark of night to the west, the only annoying part of this early visit was the sound of occasional noisy traffic, which was surprising given the distance from the road.
And the first bird to be heard was a calling male Cuckoo, his song seeming so loud in the relative quiet of the early hours.  It soon became clear that 3 male Cuckoos were calling in the area, but also, the lovely liquid bubbling call of a female Cuckoo was also heard well.
With improving light I eventually located one of the Cuckoos silhouetted in a treetop with an occasional side to side movement and waving of the tail.
Juvenile Cuckoo on passage near Hockham (August). I watched this individual as it headed south.  Alone on its journey back to Africa. 
I always amazed, as most people are, by the parasitic breeding behaviour of the Cuckoo.  Adult Cuckoos arrive with us in mid-April, call to establish territories and attract females, the eggs are laid in the foster species nest and by July, adult Cuckoos leave our shores to return to Africa.  By the time Cuckoos hatch in the foster nest the adults will be back in Africa.  Young Cuckoos fledge in August and are alone in the world, meaning they have to make their own way back to Africa without guidance from the parent birds.  Amazing behaviour.
Young Cuckoos are brownish in appearance and quiet, often they will go unnoticed as they pass through our country to begin their late summer/autumn passage.
