Do my eyes deceive me or is a magpie building a nest on the lamp standard outside my front garden? What will be the fate of the chicks in the event of a shower of rain or snow? Is there any danger of a power failure from these magpies?

These are the sheet webs of the tiny money spiders whose webs are vast in comparison to their own very small size. The webs are originally dome-shaped but when the dew settles on them they become concave and appear quite thick.

We have placed a bag of nuts on a tree outside the back window and recently, to our great surprise, we saw a house mouse scampering up the tree and eating them on several occasions, while the birds kept their distance.
