Bobby Bobolink in "Bobby's Names"

"How does it happen," Mr. Crow inquired slyly of Mr. Red-winged Blackbird, "that your friend Bobby Bobolink has all these names? It can't be—can it—that he is a rogue and is always changing his name so people won't know who he is?"
"Certainly not!" Mr. Red-winged Blackbird snapped. "Only a stupid person would ask such a question as that."Just then Bobby Bobolink himself flashed across the meadow and joined them. And Mr. Red-winged Blackbird began to talk about the weather.He was afraid that Mr. Crow intended to be disagreeable.
