Skylarks are essentially ground birds that make their living
from open spaces of grass, heath and arable fields, often
remaining inconspicuous. It’s only when the spell of spring is upon them that they take to the air for a sustained period. Song thrushes are mad about repetition. They take a phrase, run through it two or three times, then come up with another and repeat that. They like to do so from a high, often exposed
perch: the top of a mature tree is best, but even a lamp post will do.
