Size Comparison
Habitat Comparison
Great Tit
Deciduous and mixed woodland, parks, gardens, and hedgerows. Readily uses nest boxes. Highly adaptable to human environments.
Gavião-real
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Great Tit
A repetitive, teacher-teacher 'tee-cher, tee-cher, tee-cher'. Also gives ringing 'pink-pink' alarm. Highly versatile singer; over 40 song variants recorded from a single male.
Gavião-real
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
Great Tit
Widespread across Europe and Asia from Britain to Japan, and south to North Africa and Southeast Asia.
Gavião-real
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

About These Birds
Great Tit
The great tit is the largest European tit and one of the most studied wild birds in the world. Research at Wytham Woods in Oxford has monitored great tit populations since the 1940s, contributing enormously to ecology and evolution. These innovative birds famously learned to open milk bottle tops in 20th-century Britain.
Gavião-real
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.
