The gene-tree-based phylogeny from concatenation analysis of 89 genes in 45 avian and 39 mammalian genomes using maximum likelihood. a The species with images are flightless. The species Haliaeetus leucocephalus (Bald Eagle) and Pelecanus crispus (Dalmatian Pelican) were excluded from the phylogenetic analyses given the low number of retrieved sequences (n < =5). b The species with images represent the species with powered flight
