Thick-billed Flowerpecker Pachyglossa agilis

Dull gray-brown flowerpecker with streaked white underparts. Unremarkable; bill isn’t all that noticeably thick, but combination of pale vent, striped throat, and (in some subspecies) strongly streaked underparts serve to identify this wide-ranging and variable species. Like many other flowerpeckers, often associated with mistletoe, but can be found in a variety of forest types and elevations. Often heard giving a hard, slightly wet “tsip!”
