In this extended version of Tweet of the Day we feature the two species of birds whose song might on first hearing be confusing. One, the garden warbler is a summer visitor, the other, the blackcap is also a summer migrant but in recent years some birds have become resident in the United Kingdom adding a call of joy to winter days. In this edition we will hear of both birds with some discussion of their differences with Sir David Attenborough and ecologist Penny Anderson.
