VIP sequence for several passerine species. Sequence alignment for an intron of the vasoactive intestinal peptide (VIP) gene (primers described in [50]). Bases highlighted in gray show differences between the white-throated sparrow (Zonotrichia albicollis; WTSP of both morphs), Harris's sparrow (Z. querula; HASP), the white-crowned sparrow (Z. leucophrys, WCSP), the rufous-collared sparrow (Z. capensis, RUFS), the dark-eyed junco (Junco hyemalis; DEJU), the song sparrow (Melospiza melodia; SOSP), and the swamp sparrow (M. georgiana; SWSP). Yellow highlighting indicates the DraI restriction site, which is found in dark-eyed juncos and song sparrows, as well as white morphs (W) white-throated sparrows; green highlighting shows the lack of a DraI restriction site found in tan (T) morph white-throated sparrows.
