It is not unusual for the 'wild' spaces that we treasure to be multi functional, especially here in the big smoke. A place like the Brent Reservoir is not only used by birds and birders, but is home to lots of blue green algae and a sailing club. There is an unwritten rule (or perhaps it is written - I'm happy to be corrected) that says that the birds stay by the hides and the boats stay at the other end. Birds and boats don't mix kids!
Once in a while an invader from one side of the divide intrudes into the other side.
And sometimes they invade a little further than they intended. Or perhaps they really did intend to scare every bloody bird on the marsh - for a laugh. Or maybe they were rubbish at steering a boat.
This invasion did indeed freak out a lot of birds, and yes, the sight of a few hundred coots running across the water in an orc like charge was quite amusing.
But it did flush out the Little Egret. Which was nice. But I couldn't find the Black Necked Grebe afterwards. Which was not.
A Little Egret doing a bit spooked.
