Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Song & Call Comparison

Downy Woodpecker
A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.

About These Birds
オカメインコ
The cockatiel is the smallest member of the cockatoo family and one of the most popular pet birds globally. These gentle, intelligent parrots can learn to whistle tunes and mimic sounds. Wild cockatiels are nomadic, traveling in flocks following food and water availability across the Australian outback.
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.
