In the not too distant future...

Pollution/climate change has started to kill off many of Europe's birds. Each country responds trying to save some of their bird population and as such, England dispatches a team of top ornithologists to save the iconic rook combining mass incubation, special hatcheries and unnatural selection to find the hardiest possible. However progress is slow. Frustrated, Parliament demands answers. As such, the team receives an email from the Prime Minister asking "Bred any good rooks lately?"
