Crow watching

Donald loves to drop by for his tea after a long day at work.
The attraction of his visits though is purely to indulge his love of the rookery in the back of my garden, where the rooks also are returning from a days work. They hold a very squawky meeting to share the tales of each others adventures of the day and flit around surveying all the territory they oversee.
A group or a gathering of rooks is called 'gregarious'.
