Elizabeth, Lady Gwillim (née Symonds) (21 April 1763 – 21 December 1807) was an English artist and naturalist. While living in Madras (now Chennai), India, from 1801 to 1807, Lady Gwillim painted a series of about 200 watercolours of Indian birds. Produced about 20 years before John James Audubon published his famous The Birds of America (1827–1839), Gwillim's work has been acclaimed for its accuracy and natural postures––she made her watercolours by observing living birds, sometimes in their natural environments.
