Size Comparison
Habitat Comparison
Great Blue Heron
Wetlands of all types including marshes, swamps, riverbanks, lake edges, and coastal shores. Also hunts in fields and meadows.
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
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.
Hawfinch
A sharp, metallic 'tsick' call — the primary vocalization and often all that's heard. Song is a thin, reedy warble. Generally inconspicuous vocally despite its striking appearance.
Geographic Range & Migration
Great Blue Heron
North and Central America from Alaska and southern Canada to the Caribbean and Galapagos Islands.
Hawfinch
Europe, North Africa, and western and central Asia. Partially migratory, with northern populations moving south in winter.

Long, dagger-like yellowish bill
Hawfinch
Orange-brown head with a black bib and eye stripe. Warm brown back, grey nape, and broad white wing bar. Massive head and bill give a top-heavy appearance.
Enormously powerful, conical, pale bill capable of cracking cherry and olive stones
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.
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
