Obviously the only thing that has interested any of you over the weekend was the topic of the shopping trolley coots.
The whole top section of the nest (basically a big pile of stuff that floats) was not anchored to the base and during a high tide just got lifted up and floated away.
The compacted mud that is now the basis of the 'platform' is a development from spring. Last year this area was still weeds and stuff and the birds would be nesting in the trolley rather than on the trolley. The pair of Coots were nearby, apart, and looking slightly forlorn.
