The Easter Cuckoo

"We need to find a way to stop the cuckoo laying her eggs in our nests," the dunnock complained.
"There's no room for my eggs," the wagtail added.
"The baby eats all the food I can find and my babies have nothing," the pipit cried.
"It takes both of us to keep the babies fed," the sparrowhawk said.
"I can't even tell which babies are mine any more," the prinia fidgeted.

The cuckoo is notorious for laying her eggs in the nests of other birds, and letting them raise her babies.
The other birds have had enough. They have come up with a plan to teach the cuckoo a lesson – and the legend of the Easter Cuckoo begins.
