In "The Scarlet Ibis", how did Doodle and the bird die in the same way?

Both Doodle and the bird died from exhaustion. Doodle's father says the bird probably was carried by a storm and when the family sees the bird, it is bloodied and battered from its fight to stay alive in the storm. It is far away from home and the struggle has been too much for the bird to survive. Doodle dies when he trying not to be left behind by Brother, who is purposely going too fast for Doodle to keep up. The struggle to keep up with Brother is too much for Doodles' fragile heart and he dies. Thus, both Doodle and the bird were away from home, struggling against forces that were too strong for them when their bodies gave out.
