✓ Answer: B Nightingale
The source selects nightingale, but common nightingales build nests and lay eggs in them. The question appears erroneous; cuckoo may have been intended, but it is not an option. The source key is retained for traceability. The shift label is cut off or unreadable in the source; only the date is recorded.
