Bird nest in the garden

Its nice to know that birds consider your house a good environment to build their own nest. However, these birds were poor architects in building a nest compared to the birds that came last season. They built one which fell to the ground when it was almost completed. The new nest they built seemed equally condemned to a doomed fate. My father decided to remedy the situation by weaving a sort of string support into the nest using needle and thread. They have currently laid eggs in the nest!
