Species of bird

The buffy tuftedcheek or Lawrence's tuftedcheek (Pseudocolaptes lawrencii) is a passerine bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Costa Rica and Panama.

The buffy tuftedcheek and the Pacific tuftedcheek (Pseudocolaptes johnsoni) were previously considered subspecies of the streaked tuftedcheek (P. boissonneautii). The buffy tuftedcheek was then separated with the Pacific as a subspecies of it. Though some authors in the early twentieth century treated the Pacific as a species, major taxonomic systems did not begin treating the buffy and Pacific tuftedcheeks as separate species until the mid 2010s. The American Ornithological Society and the Clements taxonomy were the last; they implemented the split in 2022. The buffy tuftedcheek's alternative English name and it specific epithet commemorate the American amateur ornithologist George Newbold Lawrence. The buffy tuftedcheek is monotypic.

The buffy tuftedcheek is found from the central part of Costa Rica's Central Highlands south into western Panama as far as Veraguas Province. It inhabits humid montane evergreen forest, where it favors somewhat open tracts, the edges of denser tracts, and clearings with scattered trees. In elevation it ranges from to timberline at about .

The buffy tuftedcheek is a year round resident throughout its range.

The buffy tuftedcheek's diet is mostly a wide variety of arthropods but also includes small amphibians. It forages singly or in pairs and frequently joins mixed species feeding flocks. It forages by clambering along branches from the forest's mid level to the canopy. It does most of its foraging in epiphytes, among which it favors bromeliads. It also seeks prey in mosses and among clumps of dead leaves.

The buffy tuftedcheek is believed to be monogamous. It nests between January and May in Costa Rica. It nests in a cavity in a tree, either natural or one made by a small woodpecker, which it lines with plant matter like brown tree fern scales. Only one nest has been extensively studied. At it the single egg and nestling were tended by one adult. The nestling period was at least 29 days.

The buffy tuftedcheek sings mainly in the breeding season, a "few well spaced staccato notes followed by a liquid gurgling trill peek peek prrreeee e e e". It usually sings the phrase one time but occasionally repeats it several times. It calls throughout the year, usually in the morning while foraging, a "loud, metallic, staccato peek! or spik!". The song is assumed to have a territorial function while the call is thought to be for keeping contact with a mate.

The IUCN has assessed the buffy tuftedcheek as being of Least Concern. Though it has a limited range and its population size is not known, the latter is believed to be stable. No immediate threats have been identified. It is considered uncommon to fairly common in Costa Rica and rare in Panama. It occurs in several protected areas.
