Artists can sometimes form a lasting relationship with their subject. In this case, Yorkshire-based wildlife painter Jonathan Pomroy has conducted a lifelong affair with one of the fastest and highest-flying birds – the swift. On Crescent Wings is drawn from his numerous sketchbooks and his portfolio of paintings that capture this glorious and mysterious bird on the wing and, just occasionally, in the nest. The entire brief cycle of arrival, nest-building, mating, rearing the young, feeding and departure is observed and illustrated. On Crescent Wings provides remarkable insights into swift behaviour and encourages all of us to welcome and help conserve these enigmatic summer visitors.
