From extinct to backyard regular: Bringing the woodpecker back to your Irish garden

Father and (presumed) woodpecker son (right in flight). Great spotted woodpeckers (dendrocopos major).
This summer, I was out shoving the mower around when a persistent mechanical bleat broke through the racket I was making.
I’m a life-long wildlife lunatic, so I executed a soft pad/side shuffle to the edge of the woodland. The consistent pleading of an unfamiliar bird was right overhead. I threw myself down on my back amid the woodlice, muck, and mouldering leaves, peering up the trunk of an old and partially rotting oak tree.
