Final answer:
The bird in the bleeding tree had blue-and-pink stripes and may symbolize a deeper message of caution or humility in its medieval context.
Step-by-step explanation:
The bird referenced, which appears in the bleeding tree, is a bird with blue-and-pink stripes, as per the initial text you provided. This bird stands out in contrast to others, as stripes during medieval times were associated negatively and symbolized chaos and disorder. This could suggest that the artist, Eadfrith, possibly was using the depiction of the bird to convey a deeper meaning, perhaps a warning about evil, or as an expression of humility, considering the period's cultural significance of stripes.
