Passage Summary: Seychelles warblers usually stay home to help their parents because there is no room to start their own nests. However, when moved to a new, larger island with plenty of space, they continued to stay home and help anyway.

Reasoning: N/A

Analysis: The paradox lies in the fact that the birds' 'cooperative breeding' behavior was attributed to a lack of space, yet the behavior persisted even when space was no longer an issue. To resolve this, we need a piece of information that explains why the birds would still choose to stay with their parents despite the availability of new territory. Perhaps the new island's territory was of poor quality, or perhaps the birds' behavior is governed by factors other than just the sheer amount of land available. Look for an answer that provides a benefit to staying or a drawback to leaving that applies even on the larger island.
