About These Birds
Black-necked Woodpecker
The Black-necked Woodpecker is a medium-sized woodpecker with barred black-and-white back, a yellow crown and nape, and a distinctive black collar across the lower throat. It is endemic to Peru, inhabiting deciduous and semi-deciduous forest along the western Andean slopes and adjacent inter-Andean valleys. It forages on tree trunks and branches, excavating insects from bark and searching for ants.
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
