Ibises & Spoonbills
: PLATALEIFORMES (although some authorities will list under PELECANIFORMES)
: Threskiornithidae, which is currently divided into 2 subfamilies, with 28 extant species of Ibis under 12 genera, and 6 species of Spoonbill under a single genus.
The above reflects the traditional treatment of keeping Ibises and Spoonbills neatly separated as sister subfamilies.
However, recent analysis has shown that this is incorrect and that Spoonbills should actually come under Threskiornithinae, thereby making the subfamily Plataleinae obsolete. In addition, a new subfamily Eudociminae has been introduced to the “Taxonomy in Flux” system. This subfamily includes 8 of the species of Ibis (genera Eudocimus
Whilst I take note of the above, the main purpose of my list is to show the different species and their respective scientific names in a logical order, consequently I’ve retained the traditional subfamily split.
The following is a complete systematic listing at genus level.
This list is for personal reference, which is why certain species (12no) are highlighted – these being the species that I have both seen and photographed.
Ibises are long-legged wading birds with long down-curved bills that they use for probing in the mud for crustaceans or other small food items. Most species nest in trees often with Herons, and/or Spoonbills to which they are closely related.
