Hadada Ibis - a photo on Flickriver

Hadada Ibis

Hadada Ibis (Bostrychia hagedash) is a common species in much of sub-Saharan Africa, including Ethiopia where I photographed this individual. There are three reconised subspecies and this is nilotica found in East Africa, and is the largest and longest billed. The name Hadada is onomatopoeic from the call, which is a familiar background African sound. Here it is on Xeno-canto: www.xeno-canto.org/512301 , though you need to listen for a few seconds until you get the full "Ha-da-daaa". Juveniles are rather dull and matt, but adults have a purple and green iridescence on the wings, plus a white moustache. During the breeding season the bill develops a bright red stripe like this one. They probe for invertebrates (insects, millipedes, earthworms) using the long curved bill but will also take occasional lizards. Now here's a mystery; If you look at the leading edge of the wing you can see two small hooks protruding. But I can find no reference to these, nor can I see them on any of the many other photos of Hadada Ibis on Flickr. If you know what they are do please let me know. Interestingly the scientific name Bostrychia means a small curl, or a lock of hair, and I wonder if the family was named after this inconspicuous feature on the wings. Bostrychia was coined by George Gray in 1847, but the genus contains five African Ibises, none of which have a crest (so presumably not named after a lock of hair).
