This morning as I passed there were some Canada Greese in Ma 'Gyptian's spot so I looked about and spotted her napping on the other side of the path beside a calmer stream.
This evening she was up and about in her previous spot, all alone and looking so desolate.
I think I may have identified some detached fluffy chick plumage lying on the grass.
I hope the culprit wasn't a dog.
