birds' nest

I'm pleased to see that the birds are keeping up with the times and incorporating new fibres into their nests.

David found this tiny empty nest in the camellia courtyard yesterday and we are intrigued by how the birds have woven in an unknown green-ish fuzzy fibre—quite coarse so it didn't come from the clothes drier which has an outlet there.
The pieces of dry grass are fragile and need the green fuzz for stability.
