Size Comparison
Habitat Comparison
Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
Shoebill
Freshwater swamps dominated by papyrus and other dense aquatic vegetation in tropical East Africa.
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.
Shoebill
Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.
Geographic Range & Migration
Common Starling
Native to Europe, western Asia, and North Africa. Introduced to North America, South Africa, Australia, and New Zealand.
Shoebill
Central and East Africa from South Sudan and Ethiopia south to Zambia. Largest populations in South Sudan and Uganda.

Blue-grey plumage overall with a slightly darker back and wings. Powder down gives a washed-out appearance. Small tuft on the back of the head.
Massive shoe-shaped bill, one of the largest of any bird — pale yellowish-grey with darker markings
About These Birds
Common Starling
ホシムクドリ（Sturnus vulgaris）— ユーラシア原産で北米・豪州・南アフリカに移入された。金属光沢のある羽と白い斑点が特徴。巨大な群れ（マーモレーション）を形成する。
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
