How are Doodle and the scarlet ibis both alike and different?

When the family first sees the ibis outside in the bleeding tree, there is a paragraph full of imagery describing what the bird looks like. This description is extremely important, because at the very end of the story, Doodle is connected back to the scarlet ibis through the appearance of his red blood and his long, thin limbs and neck. In order for this connection to really resonate, readers must have a clear image in their minds of what the ibis really looks like.

"On the topmost branch a bird the size of a chicken, with scarlet feathers and long legs, was perched precariously. Its wings hung down loosely, and as we watched, a feather dropped away and floated slowly down through the green leaves."
