About These Birds
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.
Andaman Woodpecker
The Andaman Woodpecker is a vulnerable large woodpecker with a 36.8 cm wingspan, weighing 190.5 grams, endemic to the Andaman Islands. It excavates nest cavities in large trees within primary forest. Deforestation of the islands poses a significant threat to its survival.
