Davis 1957 Plyp de Santiago, 1 km NW Mangawillo, China Nov. 3, 1957. In a.m. hunted in deep palm forest, and along open field borders, 4 mi. NW Mangawillo. The palm forest seems to have few tree birds, and many of them are found high in the tall deciduous trees that tower above the palms. Below the palms, there is considerable low un- derstory in some areas, and in others, the terrain is relatively open. In either situation are birds at all common. The Ant Tanager was taken from low under- brush beneath dense palms, at the edge of a trail. I have yet to see groups of Ant Tanagers, as at San Blas, for example. Both Tanagers taken thus far were solitary. Ten-tailed Warblers seen commonly in the palm forest! At San Blas, have not yet been noted here. Woodcre- ers (Xiphorhynchus) were seen frequently, both in the palm forest + adjacent deciduous forest. Sejidos, colaptes not noted yet. The hummer taken today was molting & badly shot up; the skin is very poor, it had short (1+ mm. long) white postocular streaks, these not visible in skin. Upper mandible black, lower pale red or flesh color, on proximal two thirds, black on distal third. Rose-Throated Becards were seen several times, 20-30 ft up in deciduous forest. They are common here. The 6 collected was in full plumage save for several rose feathers in its throat. Skull was fully ossified. Unless skull ossification is quite rapid in this species, it seems likely that it takes
