Vanescaves is a probable clade ofstrisorean birds that include the cladesSteatornithiformes (the oilbird),Nyctibiiformes (the potoos),Podargiformes (frogmouths), andApodimorphae (owlet-nightjars, swifts, and hummingbirds). Some molecular studies do support the grouping of these birds,[1][2][3] others offer conflicting positions of the non-apodimorphaean strisoreans.[4][5][6] In 2019 the authors Chenet al. performed a combined analysis using 2289ultra-conserved elements [UCEs], 117 morphological characters from extant and fossil taxa found support in this clade.[7] The authors then proposed to name this group, which its meaning isLatin 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 AmericanpoetEmily Dickinson which features ahummingbird as the main subject.[7] In 2020 Chen & Field named the two major subclades of this group, withSedentaves (oilbirds and potoos) andLetornithes (frogmouths, owlet-nightjars, swifts, and hummingbirds) for their crown-groups.[8]
Below is the overall phylogeny of Vanescaves as well as their sister groupCaprimulgidae after Prumet al. (2015),[2] White & Braun (2019),[3] Chenet al. (2019),[7] and Stilleret al. (2024),[9] withphylocode names following Chen & Field (2020).[8]
