But I only found a grackle.
Then I started looking
for a long-legged crow/grackle for the large reptile tree (LRT, 1151 taxa), because basal Euornithes are all long-legged, terrestrial birds. Grackles/crows were short-legged exceptions that needed a long-legged ancestor.
I finally found one.
It’s the Eurasian stone curlew (Burhinus oedicnemius) aka? thick-knee (maybe previously known as: Oedicnemius longirostris, Fig. 1).
Oedicnemus longirostris (aka?: Burhinus oedicnemus Linneaus 1758) is the extant Eurasian stone curlew or thick-knee. Length: up to 46cm. Large yellow bulging eyes are adaptations to nocturnal hunting of small tetrapods and invertebrates. Long legs and a terrestrial lifestyle are primitive for all neognath, euornithine birds. This taxon is derived from a sister to Ciconia and basal to grackles, like Quiscalus (below) as well as the Aramus and Threskiornis clades. Note the tiny pedal digit 1.
I was also looking for a megapode.
Any megapode. Could not find skeletal material on the Internet. The good folks at the Smithsonian sent me some bits and pieces. That solves yet another phylogenetic problem.
