Terror bird phylogeny cherry picks wrong outgroup taxon again
LaBarge, Gardner and Organ’s 2024 paper on terror bird
phylogeny followed tradition in cherry-picking the long-legged South American seriema, Cariama, for their outgroup taxon, rather than the LRT tested, similar, but different enough, long-legged African secretary bird, Sagittarius (Figs 1, 2).
Figure 5. Cariama compared to Sagittarius. The former is closer to flamingos. The latter is closer to terror birds.

Cariama turns out to be ancestral to the flamingo,
Phoenicopterus, a genus found on both hemispheres.

Following outdated phylogenies will get you published.
Finding phylogenies that are outdated will get you ostracized.
Run a test yourself to find out which taxon is basal to the terror birds.
