Song & Call Comparison
Great Blue Heron
Deep, harsh, croaking 'frahnk-frahnk' call in flight. Also gives low guttural grunts at the nest. Alarmed birds give repeated croaks. Mostly silent for such a large wader.
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.

Long, dagger-like yellowish bill
Shoebill
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
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
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.
