QUIRKY WORLD ... Offspring suffer when sparrows upset love nest

Britain: When a cheating spouse upsets the sparrow love nest, it is the children who suffer, scientists have discovered.

Male sparrows whose mates are unfaithful bring home less food for their offspring, a study has shown.

Sparrows form monogamous partnerships but, as humans well know, some marriages are more successful than others. Many female sparrows are unfaithful and have offspring with other males. However, their infidelity comes at a cost, according to the research.
