Blond-crested Woodpecker
Celeus flavescens
Fairly large and strikingly-plumaged woodpecker with a yellow-crested head contrasting with a largely black body which is variably scaled with yellow spots depending on the subspecies, and a yellow rump. Males have a red moustache. Found in both wet and dry forests, usually avoiding the interior, and in wooded savannas.
Identification
The blond-crested woodpecker is about 27 to 30 cm (11 to 12 in) long. The nominate subspecies weighs 110 to 165 g (3.9 to 5.8 oz). Males of both subspecies have a wide bright red malar area and cheek; sometimes it extends around the eye and occasionally includes the lower forehead; females have black streaks instead of red on the malar and cheek and no red elsewhere. In the nominate subspecies, adults of both sexes have a pale creamy buff to yellowish white head including the long, pointed crest, chin, and throat. Often the side of the neck has black streaks. The adults have a black mantle and upper back with a buffish white to pale yellow lower back, rump, and uppertail coverts; the coverts sometimes have black bars. Their flight feathers are black with narrow white bars and some have white tips. Their wing coverts are barred black and white. Their tail feathers are black with whitish edges or bars on the outermost pair. Their lower neck and underparts are black with a hint of pale barring on the flanks and undertail coverts. Their thighs are pale yellow to buffish with black spots or streaks. The adult's bill is horn-colored or sometimes blue-gray to black with a paler mandible, their iris red or red-brown, and their legs blue-gray. Juveniles are similar to adults but are duller and have more black on their face. Subspecies C. f. intercedens is whitish to buff-white on the head and lower back, and sometimes has some rufous in the flight feathers.<p>The main call is a "[r]esonant loud 'tsew' or 'wee' repeated up to seven times". It also makes a "well-spaced series of 'wheep' notes", an "aggressive 'tttrrr'", and a "raucous 'wícket wícket'." Its drum is weak "evenly pitched short rolls".
Taxonomy
The blond-crested woodpecker was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other woodpeckers in the genus Picus and coined the binomial name Picus flavescens. The specific epithet flavescens is Latin meaning "golden-yellowish". Gmelin based his description on the "yellow-crested woodpecker" from Brazil that had been described and illustrated in 1776 by the English naturalist Peter Brown. Thomas Pennant had provided Brown with a drawing of the bird. The blond-crested woodpecker is now one of 13 species placed in the genus Celeus that was introduced in 1831 by Friedrich Boie.<p>The blond-crested woodpecker has two subspecies, the nominate C. f. flavescens (Gmelin, JF, 1788) and C. f. intercedens (Hellmayr 1908). What is now the ochre-backed woodpecker (C. ochraceus) was previously included as a third subspecies.

Range and habitat
The blond-crested woodpecker's subspecies C. f. intercedens is the more northerly of the two. It is found in western Bahia, Goiás, and Minas Gerais in east-central Brazil. The nominate subspecies is found southeast of it, from southern Bahia to Rio Grande do Sul and into eastern Paraguay and Argentina's Misiones Province. The species inhabits the interior and edges of humid forest and also gallery forest, savanna, caatinga, and orchards.

Behavior
The blond-crested woodpecker is a year-round resident throughout its range.<p>The blond-crested woodpecker's diet is arboreal ants, carpenter ants, termites, and lesser but still significant amounts of fruits and berries. It generally forages at the forest's middle level to its canopy but also on the ground, capturing insects by gleaning, probing, pecking, and hammering. It usually feeds in pairs or small groups. It is an important pollinator and disperser of seeds.<p>The blond-crested woodpecker breeds between April and June in eastern Brazil and between October and November in Argentina. It excavates a nest cavity in a tree or an arboreal ant nest. Nothing else is known about its breeding biology.

Antioquia Bristle-Tyrant
Pogonotriccus lanyoni
Rare flycatcher known only from a few sites in the Colombian Andes, mainly in the northern part of the central range. It is fairly small and mostly yellow, with a gray crown and broad, yellow wingbars. Yellow and gray smudges on ears can be very indistinct. Often confused with the much more common Yellow-olive Flycatcher, but bill is narrower, wingbars are brighter yellow, and voice is different. Typical song is a short burst that starts off as a dry rattle and then morphs into airy squeaking. Inhabits humid forest and sometimes joins mixed species flocks.
Ashy-fronted Bulbul
Pycnonotus cinereifrons
A drab medium-sized bird of lowland forest and edge on Palawan and neighboring islands. Dull brown overall with paler brown underparts and a whitish throat and center of the belly. Note the fine streaking on the cheek and the olive edging to the wing and tail feathers. Somewhat similar to Sulphur-bellied Bulbul, but Ashy-fronted lacks the yellow belly and pale eye. Song consists of very short, medium-pitched warbled phrases, repeated at short intervals.
Rufous-winged Illadopsis
Illadopsis rufescens
A mid-sized, chunky, drably colored babbler. Has a white throat and pale gray underparts, often with some darker olive-brown on the breast. Found in the understory of rainforest at low and middle elevations, usually in pairs. Shy and skulking, and rarely seen unless searched for. Similar to other illadopsises, and best located and distinguished by voice. Visually most similar to Puvel’s Illadopsis, but found in different habitat, slightly smaller, and grayer, less buffy, on the underparts. Paler below than Brown or Pale-breasted Illadopsises. Most often detected by distinctive voice: a series of several whistles in an up then down pattern that is weirdly reminiscent of trying to start a car.
