Twitch by M. G. Leonard

Can a birdwatcher outwit a convict? Twitch has three pet chickens, four pigeons, swallows nesting in his bedroom and a passion for bird-spotting. On the first day of the summer holidays, he arrives at his secret bird-watching hide to find police everywhere: a convicted robber has broken out of prison and is hiding in Aves Wood. Can Twitch use his talents for bird-spotting to hunt for the dangerous prisoner and find the missing loot?
