Abstract

Microsatellite markers were designed to be of utility for genotyping multiple species of birds, including those of conservation concern, hence saving resources and enabling species/genome comparisons. We used the proven approach of Dawson et al. (Mol Ecol Resour 10:475–494, 2010) and assessed markers in multiple species, including nine species of conservation interest. We ensured both primer sequences matched multiple species (13 loci) or designed primer sets from expressed sequence tags (2 loci). Eleven primer sets were 100 % identical to the zebra finch (Taeniopygia guttata) and a second passerine species and/or the chicken (Gallus gallus). All 15 loci were polymorphic when assessed in a non-source species (Gouldian finch, Erythrura gouldiae) suggesting utility in multiple species. Four of the five Z-linked loci were assessed in at least nine additional species each (including ratites). All were variable in multiple species, demonstrating cross-species utility and potential for identifying Z chromosome rearrangements.
