I thought that this article on One for sorrow, two for joy ... why we must protect magpies was very interesting and humane. Chris Packham defends the magpies who have historically been treated with suspicion. He recommends that people fill their bird feeders as a way to encourage little birds rather than resorting to the desperate measures the Songbird Trust are suggesting - a cull of magpies by bird lovers.
