After being rescued from a cat, it was put into an openwork basket, covered, but leaving a cat-proof aperture. The fond parents found it at once and are feeding it. It is, of course, very late in the year for young blackbirds to be hatched ; but three broods are, I think, tolerably common, commoner, perhaps, than with any other bird. The birds are not only more than usually philoprogenitive, they are more than usually courageous. One cock-bird actually landed on the back of a cat that approached the nest, and clung there, pecking the cat for some considerable distance, including the passage of a privet hedge. Partridges are perhaps yet more courageous, and will persistently attack a carrion crow which approaches their brood.
