What is Doodle's reaction to the scarlet ibis that goes astray in the storm?

Doodle was saddened by the birds death. On his own, he pulled it away and gave it a funeral. He also lost his appetite.

Doodle remained kneeling. "I'm going to bury him."
"Don't you dare touch him," Mama warned. "There's no telling what disease he might have had."
"All right," said Doodle. "I won't."
Daddy, Mama, and I went back to the dining-room table, but we watched Doodle through the open door. He took out a piece of string from his pocket and, without touching the ibis, looped one end around its neck. Slowly, while singing softly "Shall We Gather at the River," he carried the bird around to the front yard and dug a hole in the flower garden, next to the petunia bed. Now we were watching him through the front window, but he didn't know it. His awkwardness at digging the hole with a shovel whose handle was twice as long as he was made us laugh, and we covered our mouths with our hands so he wouldn't hear.
When Doodle came into the dining room, he found us seriously eating our cobbler. He was pale, and lingered just inside the screen door.

"Did you get the scarlet ibis buried?" asked Daddy.
Doodle didn't speak but nodded his head.
"Go wash your hands, and then you can have some peach cobbler," said Mama.
"I'm not hungry," he said.
