A Surrealist composition by René Magritte featuring hybrid leaf-birds on a red shore. This 1942 work explores the metamorphosis between the animal and botanical worlds.

René Magritte painted Treasure Island (L'Île au trésor) in 1942 during the German occupation of Belgium. This period marked a transition in his artistic practice. He began to move away from the flat, literal style of his 1930s work toward a more textured and painterly application of oil. The composition focuses on his recurring motif of the leaf-bird. These hybrid entities appear to grow directly from the red earth like plants while retaining the clear anatomical shapes of birds. The central group consists of several birds with plumage that mimics the veins and internal structure of leaves. One bird on the left extends a wing, revealing a pattern identical to a large, serrated leaf. They stand on a rocky, rust-coloured mound that overlooks a calm sea. The horizon line is positioned low in the frame, giving prominence to a pale blue sky filled with soft, horizontal cloud formations. Magritte used these metamorphoses to question the nature of representation and the arbitrary boundaries humans place between different categories of life. The title refers to the 1883 adventure novel by Robert Louis Stevenson, though the connection is poetic rather than a direct illustration of the text. Magritte often selected titles after a work was finished, frequently during evening gatherings with his Surrealist colleagues in Brussels. The intention was to find a title that would provide an additional layer of mystery without offering a simple explanation of the visual content. This painting belongs to a series of works from the early 1940s where Magritte explored the fusion of animal and botanical forms, a theme that became a signature element of his mid-career output.
