Saltwater and Shore is the final volume of Sidekick’s wildly ambitious Birdbook series – a collaborative alternative ornothopedia where every species gets equal billing. This time we find ourselves flung beyond the limits of the island, before being gathered in again at its outcrops, outposts, briny mouths and sandy fringes, where well-established stars like the puffin jostle with the lesser-known knot, scaup and razorbill, the whimbrel, spoonbill and turnstone. It’s a bustling, polyphonic cliffside colony of a book, a multitude of individual voices and dynamic images poised to spill into the air and take flight in the willing imagination.
