Wynter's work evolved significantly throughout his career, encompassing various styles and approaches. In the 1940s and 1950s, Wynter explored abstraction, experimenting with bold colours, gestural brushwork, and organic forms. He was particularly interested in the relationship between art and nature, often drawing inspiration from the Cornish landscape where he lived and worked. His early abstract works often featured dynamic compositions and rhythmic patterns, reflecting his fascination with the natural world.

In the 1960s, Wynter's work shifted towards abstraction, influenced by his interest in science and nature. He began to create bold, geometric compositions inspired by natural phenomena such as landscapes, seascapes, and celestial bodies. His use of vibrant colours and dynamic shapes reflected his fascination with the interplay of light, colour, and energy. Wynter's later works explored the possibilities of new materials and techniques, including acrylic paint and collage. He continued to push the boundaries of abstraction, creating experimental compositions that blurred the line between painting and sculpture.

In this artwork, Wynter presents a vibrant and dynamic composition featuring a bird nestled among a cluster of rocks. The bird's presence is central to the composition, serving as a focal point that draws the viewer's eye and anchors the scene. Despite its small size, the bird exudes a sense of vitality and presence, its form rendered with fluid, gestural brushstrokes that convey a sense of movement and life.

Surrounding the bird are clusters of rocks rendered in bold, abstract shapes and vibrant colors. Wynter's use of colour is particularly striking, with hues of blue, green, and yellow intermingling to create a sense of depth and dimension within the composition. The rocks themselves seem to pulse with energy, their forms shifting and morphing in response to unseen forces. Despite its abstracted nature, "Bird Among Rocks" evokes a sense of the natural world and the interconnectedness of all living things. The bird, with its delicate form and graceful presence, serves as a reminder of the beauty and fragility of life, while the rocks symbolize the enduring strength and resilience of nature itself.
