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.
Acorn Woodpecker
The Acorn Woodpecker is a highly social woodpecker weighing about 79g of western North American oak woodland. It stores thousands of acorns in specially drilled 'granary trees' shared by the group.
