So pleased to see this paper out! It represents my very best effort at trying to resolve the phylogeny of the nightbirds (superorder Strisores), using a novel genome-scale marker (ultraconserved elements). I initially uncovered some conflicting signal pertaining to the relationship between the potoos and oilbird, and subsequently designed a series of analyses to try and tease that signal apart. It wasn't easy, but in the end I've uncovered significant support for the topology seen below. Now I can proceed with further analyzing the visual adaptations to nocturnality in this group, in order to unravel their evolutionary history. See my PUBS page for the paper, published in the journal Molecular Phylogenetics and Evolution. Thanks to friend and colleague Daniel J. Field for use of the beautiful photos.
