What is in this image? Describe it as if you were explaining it to someone from the 15th century.

This image is a drawing that captures various shapes, put together to form the likenesses of birds. The concept may remind you of a tapestry or stained glass, popular in churches and noble houses during your time. The birds are stylized, composed of geometric shapes and straight lines rather than depicted with natural curves and feather details one would see in real life. They are positioned against a backdrop that suggests they are soaring skyward, with a sun-like circle in the upper left. The whole image is partitioned into sections resembling window panels, each component clearly differentiated to make the birds and their environment distinct yet simplistic.
