The first butterfly on the wing, fresh leaves on the trees, lambs gambolling in the pasture, herald the arrival of spring.
But why do these things happen? If mad March hares mate in the spring, why do deer rut in the autumn?
Why is the woodland floor carpeted with flowers while the trees above have yet to leaf? This programme celebrates the delights of spring, and casts light on some of its mysteries. Narrator Hugh David Producer DILYS BREESE BBC Bristol
