Answer
Birds were frequently featured in the collages of German artist Kurt Schwitters. Renowned for his use of unconventional and discarded materials, Schwitters often incorporated fragments of bird imagery, such as feathers, wings, or cutouts from ornithological books. By integrating these avian elements, he aimed to evoke a sense of movement and life within his multifaceted compositions, inviting viewers to engage with the unexpected and poetic aspects of everyday objects.
