Robust Woodpecker
Campephilus robustus
Huge woodpecker found in humid forests including Araucaria forests. The head is mostly red with a short crest and strong greenish bill. The wings and tail are black, but in flight, the wings are spotted with cinnamon patches above and below. Note the large buff patch on the back and heavy barring below. Males have white ear spots while females have a prominent white moustache.
Identification
The robust woodpecker is 32 to 37 cm (13 to 15 in) long and weighs 230 to 294 g (8.1 to 10 oz). Both sexes have whitish upperparts with a pale buff or cinnamon tinge. Their scapulars and the wings' coverts and upper surface are black with small rusty-buff spots on the flight feathers' inner webs. The wings' underside is blackish brown with rufous-buff spots on the flight feathers. Their tail is black . Their underparts are buff to whitish buff with black bars that are narrower on the belly. Adult males have an entirely red head and neck with a small black and white spot on the ear coverts. Adult females do not have the covert spot. They do have a wide whitish strip with black edges that extends from the bill to the ear coverts. The adult's bill is a long horn-colored chisel, their iris white to yellow-white, and their legs dark gray. Juveniles resemble adults but are duller and browner; their upperparts are whiter and their underparts have less contrast.
Taxonomy
The robust woodpecker was for a time placed in genus Scapaneus that was later merged into genus Phloeoceastes that was itself merged into the current genus Campephilus. The robust woodpecker is monotypic.

Range and habitat
The robust woodpecker is found in eastern Brazil from Bahia and Goiás south to Rio Grande do Sul, in eastern Paraguay, and in northeastern Argentina's Misiones and Corrientes provinces. It inhabits intact humid and Araucaria moist forests; it shuns disturbed forest unless large trees remain. In elevation it ranges from sea level to 2,200 m (7,200 ft).

Behavior
The robust woodpecker is a year-round resident throughout its range.<p>The robust woodpecker forages at all levels of the forest with some preference for the middle level; it only rarely feeds on the ground. It tends to hunt on tree trunks and the bases of limbs, where it pecks and hammers vigorously and also probes and flakes off bark. It tends to forage singly, in pairs, or in family groups, and only rarely joins mixed species feeding flocks. Its diet is mostly adult and larval beetles but also includes some berries.<p>One robust woodpecker nest was observed during excavation in May; it held young in July. Nothing else is known about the species' breeding biology.<p>One robust woodpecker vocalization is a "psó-ko po-po-po-po-rrat" series. Two calls are "kee" and "kew" that are given both in flight and while perched. Its drum is a double tap "to-plóp" or "thump-ump".

Van Dam's Vanga
Xenopirostris damii
Large, big-billed vanga with white underparts. Males have a black hood, and females only a black cap. Rare Madagascar endemic that is found very locally in dry deciduous forest in the north and northwest. Can be found solo or in pairs, sometimes in flocks with other vangas. Most common vocalizations are long, penetrating whistles and a short scold. Separated from Lafresnaye’s and Pollen’s Vangas by range. Separated from Madagascar Cuckooshrike by much larger bill and white rather than gray underparts.
Gray Catbird
Dumetella carolinensis
Medium-sized songbird with a smooth gray body, black cap, and rusty-red undertail coverts. Sexes alike. Occurs in shrubby habitats, especially thickets or second-growth at the edge of forest, often near water. Usually quite skulking, but sometimes pops up conspicuously, especially when singing. Occasionally visits feeders, especially for suet. Listen for complex, jumbled song, which often includes mimicry of other species.
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.
