Size Comparison
Habitat Comparison
Greater Flamingo
Shallow alkaline or saline lakes, coastal lagoons, mudflats, and salt pans. Requires large undisturbed areas for breeding colonies.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Greater Flamingo
Loud, nasal goose-like honking 'ka-ha' calls, often in chorus at breeding colonies. Also gives softer gabbling and grunting sounds while feeding and preening.
Harpy Eagle
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Geographic Range & Migration
Greater Flamingo
Africa, southern Europe, the Middle East, and the Indian subcontinent. Irregular visitor to northern Europe.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

How to Tell Them Apart
Greater Flamingo
Predominantly white-pink plumage with bright crimson-pink wing coverts revealed in flight. Long pink legs and a sinuous neck. Intensity of color depends on diet.
Large, downward-bent bill — pink with a black tip, adapted for filter feeding
Harpy Eagle
Slate-black upperparts and head with a pale grey breast and white underparts with black barring. A distinctive split grey crest rises when the bird is alarmed.
Massive dark hooked bill, one of the largest of any eagle
About These Birds
Greater Flamingo
The greater flamingo is the most widespread flamingo species and one of the most recognizable birds in the world. Their pink color comes entirely from carotenoid pigments in their crustacean and algal diet. Flamingos are social birds that breed in enormous colonies sometimes numbering tens of thousands.
Harpy Eagle
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
