Extent and pattern of MB skeletal distribution in all 40 specimens sampled. The extent of MB skeletal distribution is expressed in % of skeletal regions containing MB. The specimens are classified following the phylogeny of Prum et al. [52]. The skeletal scheme used here is representative of the general bird skeleton depicting all considered elements, regardless of the species
