Explanations
Discover subjects by question, topic or field. Each Explanation is a research-stage Counterpedia Entry: an attributed account of what changed, what a rule requires, or which classification applies, together with the editions and qualifications that bound the answer.
These are reading paths into the canonical Entry reader, not a second account. The Entry remains the single source of the full account, its provenance and its source candidates.
Flagship explanation · Life sciences
Did the bird change, or did the classification?

Authorities and editions preserved

What this Entry preserves
- Each named authority and checklist edition beside the treatment it gives.
- The recorded research cutoff, including AviList's issue-under-consideration state.
- Two synthetic observation examples, labelled as synthetic.
- The complete why-not specimens, including the qualified case about an earlier sighting.

Descriptions of current or pending states refer to the recorded research date. A later checklist, standard or procedure may have changed; this collection does not silently update the account.
