VIP sequence for several passerine species. Sequence alignment for an intron of the vasoactive intestinal peptide (VIP) gene (primers described in ). 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.
