Lake outlet, Newmillerdam, 10.15 a.m.: The sitting coot gets increasingly alarmed as the drake mallard gets nearer, dabbling around the nest. The coot’s repeated, scalding notes get more frantic until its mate swims over briefly to check things out, but the mallard soon moves on.
Back to the business of incubating, the coot keeps changing position and I get a glimpse of 8-10 greenish brownish eggs.
Its mate returns and presents the sitting bird with a spindly pencil-length twig sprouting fresh green leaves. This is accepted by the bird on the nest (I’m not saying ‘the female’ because I can’t tell the difference between the two birds) and incorporated into the car tyre-sized platform.
