Analysis of a modern bird data set. a The species network explored by our method, which contains six pairwise reticulation edges among the three vocal learners. b The posterior of the inheritance probability samples associated with the six reticulation edges using all 14,357 gene trees from exons, introns and ultraconserved elements. c The posterior of the inheritance probability samples associated with the six reticulation edges using 524 gene trees (from introns) that have more than 5 internal branches with at least 70 bootstrap support. d The number of gene trees with high bootstrap support. The number of internal branches in the gene trees with at least 70 bootstrap support is on the x-axis. The number of gene trees that have a given number of branches with at least 70 bootstrap support is on the y-axis. The three panels from left to right correspond to gene trees from exons, introns and ultra-conserved elements, respectively
