Vanescaves
clade of birds
Vanescaves is a probable clade of strisorean birds that include the clades Steatornithiformes (the oilbird), Nyctibiiformes (the potoos), Podargiformes (frogmouths), and Apodimorphae (owlet-nightjars, swifts, and hummingbirds). Some molecular studies do support the grouping of these birds, others offer conflicting positions of the non-apodimorphaean strisoreans. In 2019 the authors Chen et al. performed a combined analysis using 2289 ultra-conserved elements [UCEs], 117 morphological characters from extant and fossil taxa found support in this clade. The authors then proposed to name this group, which its meaning is Latin for "vanish birds" in reference to the disparate nature of their geographic distribution, as well as to the poem "A Route of Evanescence" by the American poet Emily Dickinson which features a hummingbird as the main subject. In 2020 Chen & Field named the two major subclades of this group, with Sedentaves (oilbirds and potoos) and Letornithes (frogmouths, owlet-nightjars, swifts, and hummingbirds) for their crown-groups.
Below is the overall phylogeny of Vanescaves as well as their sister group Caprimulgidae after Prum et al. (2015), White & Braun (2019), Chen et al. (2019), and Stiller et al. (2024), with phylocode names following Chen & Field (2020).
Begin with the source’s own compact description: “Vanescaves” is clade of birds. The dossier treats that line as a proposition to test through Vanescaves, clade and birds, not as a finished interpretation.
Why this record matters
The phrase “clade of birds” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q104855083. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2019, 2020, 2015 and 2024.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
