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

The image depicts a long-necked bird, which bears a resemblance to swans or geese known to you, but with a more pronounced curve in its neck and a prominent, expressive eye. This bird stands amidst what appears to be bands of water and reeds, indicated by simplified, flowing lines that suggest an aquatic habitat. The background features wavy lines that might remind you of clouds or the swirling patterns seen on water surfaces when disturbed by wind. The entire portrayal is rendered in simple, bold outlines, devoid of color, capturing the essence of the creature and its environment in a stark, almost emblematic manner.
