(2-CD Set) A double CD including the common calls and songs of 79 familiar bird species of towns, villages and the countryside. Classed in four categories, from simple, repeated notes to varied, unpredictable songs; the CDs are a real learning tool. The simpler calls and songs are on CD1; the more complex on CD2. The species name is announced at the start of each track, making for easy use especially for the poorly-sighted.
