Size Comparison
Habitat Comparison
Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Song & Call Comparison
Common Starling
A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
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'.
Geographic Range & Migration
Common Starling
Native to Europe, western Asia, and North Africa. Introduced to North America, South Africa, Australia, and New Zealand.
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.

About These Birds
Common Starling
紫翅椋鸟（Sturnus vulgaris）— 原产于欧亚大陆，已引入北美、澳大利亚和南非。具金属光泽的羽毛和白色斑点为特征。能形成壮观的大群（椋鸟旋舞）。
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.
