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.

Red-bellied Woodpecker

红腹啄木鸟（约75克）是一种中型啄木鸟，雄鸟具有鲜红色的头颈，得名于腹部模糊的淡红色。广布于北美东部，常见于城郊花园和树木繁茂地区。以昆虫、坚果和浆果为食，也在树洞中贮藏食物。无危；种群数量稳定且有所增加。
