Tales of the crows

Everyone knows that starlings can fly in huge flocks, performing rolling and mesmerising formations, but it is less known that rooks do the same aerial ballet right before sunset. 
There was a place in Budapest, where as winter arrives, a fascinating dance begins: rooks are showing up in enormous flocks from every direction of the darkening sky. The city is the wintering ground of these rooks who waltz for long minutes above Új Köztemető (New cemetary), just before touching down at the place they usually spend the night.
