February 23rd – Also at Chasewater, there’s some pollution happening.
This is good pollution, however. A casual observer might stand on the waterline of the now-full lake and wonder what the froth and scum is, gently lapping the shore. It’s the side effects of Chasewater once again being host to massive numbers of Gulls, who come here to roost on the water at twilight.
Yes, tens of thousands of birds frequent this reservoir in the evening, where they rest, loaf and bob gently in the wind. Whilst they do this, they preen. The scum is actually bird feathers, plucked during preening.
Biodegradable, they will rot away, or be gathered by other birds for nesting material. Recycled, naturally.
