The Wikipedia Talk page for the Hadada Ibis (https://en.wikipedia.org/wiki/Talk:Hadada_ibis) contains a nice little diatribe as to whether this is a Hadada, Hadeda, or Hadida. However, the page is considered “Low-importance” on the Wikipedia Bird Project scale.
The talk page for the Wikipedia Bird Project does not discuss whether “Low-importance” should be hyphenated. It does, however, state the position that ALL birds are of low importance by default and must have done something of note to be elevated to a higher status. No one can seem to agree about the chicken and the goose.
This ibis, however, doesn’t care.
