Rufous Mourner

Mourners are part of the genus Rhytipterna, with three species. The rufous mourner is my first mourner. There are two subspecies and I saw the nominate ssp. holerythra, found on the Atlantic slope from Southern Mexico (norther Oaxaca) south to Panama and northern Colombia (east to Santander). I saw it in Tikal NP in Guatemala. It was early in the morning and not a bird my guide noted. 

I have submitted it to iNaturalist but no identifiers are confirmed it. The second option on iNaturalist was a scarlet-rumped tanager. What really confirms it for me is the pale-based black bill, based on photos from Birds of the World, which looks quite a bit different than the scarlet-rumped tanager's bill.
