Nyctidromus merrilli




Previously N. a. merrilli   , and includes individuals assigned to N. a. insularis, N. a. intercedens, and N. a. yucatanensis. It is elevated to full species status and is the sister species of a clade containing N. albicollis   and N. derbyanus   .


Nyctidromus merrilli   is intermediate in size, and the plumage is both lighter and greyer than N. albicollis   and N. derbyanus   , with a slate-grey coloration on the crown and back being particularly noticeable. There are also conspicuous black patterns on the coverts of N. merrilli   , which in both N. albicollis   and N. derbyanus   tend to be browner. Some individuals in arid areas of Mexico are slightly more reddish in colour, but overall the three named forms within N. merrilli   (insularis, merrilli   , and yucatanensis) are similar to one another.
