About These Birds
Bay Woodpecker
The Bay Woodpecker is a large, rufous-brown woodpecker of the montane forests of the eastern Himalayas through to southeastern Asia. It has a barred rufous back, red head markings in males, and a powerful chisel-like bill. It excavates tree bark for insects, larvae, and ants in dense subtropical and montane forest.
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.
