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

The image shows a fine drawing, akin to a woodcut but with more minute details. Featured in the drawing is a bird, perched delicately on a thin branch of a tree. Its plumage is intricately rendered, showing patterns that suggest a soft texture. Sitting near the bird, and woven between the branches, is a nest cradling two eggs. These eggs, still unhatched, lie tranquilly amidst the twigs and leaves designed to protect and warm them. The depiction of the branches and leaves is detailed, showing a variety of shapes and sizes, and enriching the scene with a sense of natural abundance and peace. The entire portrayal is encased in a network of fine lines that create the forms and textures of the woodland home of this bird.
