Relationship of birds of prey to other avian species. a Venn diagrams of orthologous gene clusters in the birds of prey. Orthologous gene clusters were constructed using 25 avian genomes. Only raptor gene clusters are displayed. b Gene expansion or contraction in the 23 high-quality avian species The numbers near order and species names indicate the number of gene families that have expanded (+) and contracted (−) in each branch and species. Species in red are birds of prey. c Heatmap of enriched Gene Ontology (GO) categories for raptor common GC3-biased genes. Bird icons from the left to the right indicate Strigiformes, Accipitriformes, Falconiformes, and non-raptor birds. Z-scores for the average of normalized GC3 percentages are shown as a yellow-to-black color scale
