The first thing I did on returning home from hospital was to walk around the garden. My arrival was met by screams from the rooftop where two agitated jackdaws were positioned. They were not screams of joy. Their fledglings were sitting along the trunk of the wisteria, in the middle of a flying lesson. As I walked past, the young birds jumped down from the trunk and hopped across the lawn to the magnolia, their parents shrieking as I giggled.
