Rookie Mistake

Before cutting the grass at the back of the house I always spend some minutes picking up twigs that mysteriously seem to fall off the silver birch whether or not the wind has been blowing; my mistake has been to blame the wind as this morning I spotted the real culprits as several rooks descended on the tree and proceeded to peck away at its extremities before making off with what must be excellent nesting material – but not without dropping a good nest-load of rejects onto the lawn.
