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

In this depiction, you will find three whimsical birds, each adorned with a form of headwear commonly worn during times of cold. The first bird on the left wears a knitted cap, snugly fit and topped with a small tuft; its eyes are round with a hint of mirth. The bird in the middle is slightly different, having large, expressive eyes, and dons a cap too, though resembling more the shape of an acorn''s shell. The final bird on the right, appearing slightly larger, has its head covered by a soft hat that droops backward, ending in a puff, much like the tail on a jester''s cap.These creatures are perched all in a row upon what appears to be a branch, with expressions ranging from joyous to slightly cautious. In essence, this is a light-hearted representation, possibly crafted for the joy of young ones, each bird characterised with human-like expressions to give a sense of personality and life.
